RET Automation Controls is proud to<br />
present the Q4X laser distance sensor<br />
from Banner Engineering. Featuring<br />
superior, versatile sensing performance,<br />
the Q4X sensors are available with bipolar<br />
discrete (NPN and PNP) and analog (0-10<br />
V or 4-20 mA) output options. With highresolution<br />
capabilities, discrete models<br />
can detect objects as thin as 0.5 mm,<br />
while analog models precisely inspect<br />
part dimensions and positioning with<br />
resolution down to 0.15 mm. The Q4X<br />
is available in two sensing ranges, 25 to<br />
100mm or 25 to 300mm.<br />
Banner’s Q4X is ideal for difficult<br />
distance-based sensing applications as it<br />
easily detects objects regardless of target<br />
surface reflectivity, including black foam on<br />
black plastic, black rubber in front of metal,<br />
multicolour packaging and targets of all<br />
colours. Also available with a dual teach<br />
mode, discrete Q4X sensors can detect<br />
clear objects or changes in signal intensity<br />
due to changing colour or reflectivity.<br />
The dual teach mode in the Q4X<br />
sensor combines window thresholds on<br />
both target distance and target reflected<br />
intensity, allowing the Q4X to reliably<br />
solve difficult applications with ease. The<br />
Q4X can now detect clear objects without<br />
requiring a retro-reflector. Dual mode can<br />
be used to error-proof applications by<br />
ensuring the correct colour part is located<br />
at the correct position. With the dual teach<br />
mode, the sensor can detect small changes<br />
in reflected intensity for targets inside<br />
the distance threshold. This powerful<br />
combination allows the Q4X to solve many<br />
new applications.<br />
“Incorporating the innovative dual<br />
teach mode into the next-generation Q4X<br />
sensor provides our customers with a more<br />
powerful sensing solution for their most<br />
difficult applications,” said Dennis Smith,<br />
Senior Technical Marketing Manager,<br />
Banner Engineering. “With combined<br />
intensity and distance thresholds, the<br />
Q4X extends its world class sensing<br />
performance to clear object detection and<br />
common error-proofing applications.”<br />
Offering a simplified user experience,<br />
the Q4X provides a clear distance readout<br />
from the highly visible, angled four-digit<br />
display that is easily viewed from multiple<br />
vantage points. The Q4X also offers intuitive<br />
user setup utilizing three tactile buttons<br />
conveniently located below the display.<br />
For use in wet and high-pressure<br />
washdown environments, the Q4X is<br />
constructed with robust housing rated to<br />
IP69K. Durable FDA-grade stainless steel<br />
resists mechanical impact, over tightening<br />
and extreme vibration.<br />
To accommodate diverse industries<br />
and applications, the Q4X provides reliable<br />
detection of:<br />
• Black foam in front of black plastic in automotive<br />
interior and exterior assembly<br />
• Parts of varying colours in consumer<br />
packaged goods and automotive industries<br />
• Black rubber in front of metal in robotic<br />
assembly, especially automotive<br />
• Multicoloured packaging and secondary<br />
packaging in food, beverage and<br />
cosmetics<br />
• Part-in-place for error proofing of assembly<br />
steps<br />
• Small parts for automated assembly<br />
processes, such as caps, seals, o-rings,<br />

Thermal imaging reduces downtime and improves safety<br />
A thermal imaging service designed to reduce plant breakdowns, minimise costly<br />
repairs, optimise the production process and improve safety in the workplace.<br />
Magnet’s newly established<br />
division – Magnet Electrical<br />
Projects – offers a critical service<br />
to all industries in the electrical<br />
and instrumentation sectors,<br />
including solutions for hazardous<br />
environments.<br />
“Although the Magnet Group<br />
has provided a service to support<br />
electrical equipment, industrial<br />
instrumentation and automation<br />
throughout the country for over<br />
20 years, increased demand for<br />
expert solutions has led to the<br />
establishment of Magnet’s new<br />
formalised division,” says Johan<br />
Roets, training and site inspection<br />
manager, Magnet Electrical<br />
Projects. “Four specialist solutions<br />
sectors of this division include<br />
panels, automation, metering and<br />
onsite services.<br />
“Magnet’s onsite services<br />
encompass power quality analysis,<br />
electrical compliance auditing and<br />
power factor correction, as well as<br />
onsite electrical installations and<br />
the retrofit of air circuit breakers.<br />
“Magnet’s thermal imaging<br />
service has been designed<br />
to reduce plant breakdowns,<br />
minimise costly repairs, optimise<br />
the production process and<br />
improve safety in the workplace.<br />
By detecting irregularities that are<br />
usually invisible to the naked eye,<br />
thermal imaging – which is one<br />
of the most valuable diagnostic<br />
tools for industrial applications -<br />
allows corrective action to be taken<br />
before costly system failures or fires<br />
occur.”<br />
Magnet’s thermal imaging<br />
service forms part of a condition<br />
monitoring programme to<br />
determine when and where<br />
maintenance is needed in electrical<br />
and mechanical installations and<br />
PQ-Box 200 is a network power analyser, power meter and transient recorder in one<br />
instrument, has been developed by a-eberle especially for mobile operation and is<br />
suitable for measurements in public networks, installation category CAT IV.<br />
components. By using reliable,<br />
non invasive thermal imaging<br />
instruments, which are able to<br />
scan and visualise the temperature<br />
distribution of entire surfaces<br />
of machinery and electrical<br />
equipment quickly and accurately,<br />
preventative action is taken in the<br />
event of a fault. What’s important<br />
for production plants, is Magnet is<br />
able to perform inspections, even<br />
when systems are under load.<br />
This specialist service<br />
encompasses the provision of<br />
a full image of each situation<br />
and accurate temperature data<br />
during the monitoring of high<br />
voltage equipment, low voltage<br />
cabinets, motors, pumps and high<br />
temperature equipment, as well<br />
the detection of insulation losses.<br />
A small electrical problem can<br />
have far reaching consequences.<br />
As the efficiency of the electrical<br />
grid becomes low, more energy<br />
is used generating heat. If left<br />
unchecked, this heat can rise to<br />
the point where connections<br />
start to melt and this can result in a<br />
devastating fire.<br />
Magnet Electrical Projects is<br />
able to identify and locate a fault<br />
before costly problems occur and<br />
also advise exactly what needs<br />
to be fixed. This thermal imaging<br />
service - which extends from the<br />
examination of a fuse box, to the<br />
inspection of a large industrial<br />
installation - ensures cost savings,<br />
reduced downtime and improved<br />
safety standards.<br />

Compact chilled mirror hygrometer gives high accuracy for<br />
reliable control of sintering processes<br />
The new S8000RS chilledmirror<br />
hygrometer offers an<br />
accuracy of ±0.1°C, with a wide<br />
measurement range of -90 to<br />
+20°C dew point, making it the<br />
ideal choice for moisture control<br />
in a range of metallurgical<br />
processes, including sintering.<br />
Sintering is a process where<br />
powdered metals are bonded<br />
together to form light and strong<br />
products, from filters to machine<br />
parts. Because the powdered<br />
metal is not fully melted, the<br />
temperatures involved are<br />
relatively low – around 600°C –<br />
but careful control of moisture is<br />
essential to ensure the finished<br />
quality.<br />
Because the raw material<br />
is powdered metal, moisture<br />
present in the furnace could cause<br />
clumping or, as the moisture<br />
evaporates in the heat, large holes<br />
being created in the finished<br />
product. To avoid this, accurate<br />
control and measurement of<br />
moisture is vital.<br />
For sintering carried out 600°C,<br />
maintaining a constant dew point<br />
of -60°C in the furnace is necessary<br />
and the gas is sampled at several<br />
points in the process.<br />
A fast-responding moisture<br />
analyzer is essential so that action<br />
may be taken quickly if moisture<br />
levels rise above acceptable limits.<br />
Michell’s S8000RS uses the<br />
fundamental chilled mirror<br />
technique to measure moisture,<br />
which ensures long-term accuracy<br />
to ±0.1°C dew point as well as<br />
reliability and a fast response.<br />
The measurement range of -80<br />
to+20°C dp is ideal to ensure<br />
consistent monitoring at -60°C<br />
with confidence in the accuracy.<br />
The S8000RS is the smallest<br />
hygrometer on the market<br />
which is able to reliably reach<br />
dew points of -80°C. This small<br />
size is possible because it does<br />
not require any external cooling,<br />
which makes it well-suited to<br />
metallurgical applications where<br />
its small footprint makes it easy<br />
to install in an air conditioned<br />
instrumentation cabinet.<br />

Temperature measurement evolves<br />
Through the ages, various<br />
techniques and devices have<br />
been used in an effort to measure<br />
and compare temperature<br />
conditions: for example, the<br />
reference points of boiling water<br />
and melting ice.<br />
In the early days of ceramics<br />
manufacture, the craftsman<br />
used materials which indicated<br />
through deformation that certain<br />
(higher) temperatures had been<br />
reached.<br />
Bakers on the other hand used<br />
a piece of paper, the quicker it<br />
became brown the hotter the oven.<br />
It was known that specific<br />
materials changed state at set<br />
temperatures and this formed<br />
the basis of temperature<br />
measurement.<br />
The disadvantage of these<br />
techniques was that they were not<br />
reversible. In addition, the accuracy<br />
of the results was very dependent<br />
on the user and their experience.<br />
Thermocouples make things<br />
easier<br />
It was not until the discovery<br />
of thermometers, a little over 400<br />
years ago, that actual temperature<br />
conditions could accurately be<br />
measured.<br />
It was determined that a probe<br />
made of two different conductors<br />
forming a junction at one end had<br />
certain temperature dependent<br />
voltage producing properties – the<br />
thermoelectric effect.<br />
This voltage is proportional<br />
to the temperature difference<br />
between the hot and cold<br />
junctions.<br />
Commercial<br />
thermocouples are inexpensive<br />
and can be used in a wide range of<br />
temperature applications.<br />
Their main limitation is<br />
accuracy, they have to be in contact<br />
with the high temperature and<br />
system errors of less than 1°C are<br />
difficult to obtain.<br />
The emergence of infrared<br />
The discovery of infrared<br />
radiation by the physicist Wilhelm<br />
Herschel at the beginning of<br />
the 19th century opened up<br />
new possibilities for measuring<br />
temperature – without contact<br />
and thus without affecting the<br />
object being measured and the<br />
measurement device itself.<br />
Compared to early infrared<br />
temperature measurement<br />
devices, which were heavy,<br />
awkward and complicated to<br />
operate, the image of such devices<br />
today has completely changed.<br />
Modern infrared thermometers<br />
are small, ergonomic, easy to<br />
operate and can even be installed<br />
into machinery.<br />
From versatile handheld<br />
devices to special sensors for<br />
integration into existing process<br />
systems, the spectrum of product<br />
offerings is vast, with a variety<br />
of accessories and software for<br />
the collection and analysis of<br />
measurement data provided by<br />
the majority of suppliers.<br />
An IR thermometer can be<br />
compared to the human eye. The<br />
lens of the eye represents the<br />
optics through which the radiation<br />
(flow of photons) from the object<br />
reaches the photo-sensitive layer<br />
(retina) via the atmosphere.<br />
This is converted into a signal<br />
that is sent to the brain. Simple<br />
single point IR temperature<br />
measurement has evolved into<br />
units that now display thermal<br />
images used in applications that<br />
monitor on-line real-time molten<br />
steel temperature, to hot-spot<br />
technology that helps umpires<br />
decide if a batsman is out or not<br />
after a catch has been taken.<br />
The advantages of IR<br />
thermometers include:<br />
• Fast measurements<br />
(milliseconds).<br />
• Measurement on moving and<br />
difficult to reach objects.<br />
• Hot objects (> 2000°C).<br />
• Feedback-free measurement.<br />

All-in-one measurement station<br />
The Leuze LSC 200 is a complete<br />
system or all-in-one measurement<br />
station.<br />
Depending on the application,<br />
sensors can be used for<br />
object measurement as well as for<br />
objection detection. The Leuze<br />
LSC 200 is a complete system, or<br />
all-in-one measurement station,<br />
and is suited to applications in<br />
intralogistics and packaging<br />
operations where sensors and<br />
evaluation units are optimally<br />
The Leuze LSC 200 can also be expanded<br />
with sensors that perform<br />
identification tasks.<br />
matched to one another.<br />
Pre-installed software on<br />
the evaluation unit performs<br />
data acquisition as well as preprocessing<br />
and, depending on the<br />
task, the extraction of user data.<br />
The user data is made available<br />
via defined interfaces, such as<br />
Profibus, TCP/IP.<br />
This type of measurement<br />
station is much more than simply a<br />
complete system. Due to its flexible<br />
adaptability, it can serve as a<br />
solution platform for certain tasks,<br />
whereby, again task dependent,<br />
sensors with a wide range of<br />
performance capabilities are<br />
connected and evaluated.<br />
Essentially this means that<br />
the Leuze LSC 200 can also be<br />
expanded with sensors that<br />
perform identification tasks, such<br />
as bar code readers. Dimensions<br />
can be measured with, for<br />
example, three light curtains<br />
(length, width, height) using the<br />
optical throughbeam method.<br />
And if necessary, the width and<br />
height measurement can also be<br />
measured using scanning light<br />
section sensors or laser scanners.<br />
The length measurement can be<br />
optionally performed using an<br />
incremental transmitter.<br />
Depending on the sensors<br />
used and the properties of the<br />
objects that are to be measured,<br />
various filters can also be set in the<br />
evaluation software for optimising<br />
the measurement values.<br />
The adaptation of parameters,<br />
such as the offset adjustment<br />
when using light curtains, can be<br />
performed by means of a GUI.<br />
Leuze LSC 200 stations with<br />
Leuze CML 700i Series light<br />
curtains contain an integrated<br />
web visualisation system, adding<br />
even greater capability to this<br />
sensing solution. With this, the<br />
measurement values can be<br />
displayed and adjustment values<br />
set remotely via a standard Internet<br />
browser.<br />

Compact portable hygrometer for convenient spot checks<br />
The new MDM50 portable<br />
hygrometer quickly and<br />
simply takes spot checks of dew<br />
point or moisture content down<br />
to -50°C dew point.<br />
Because it has its own selfcontained<br />
sampling system,<br />
setting up the MDM50 involves<br />
simply connecting the hose to the<br />
sample point: there are no extra<br />
sample conditioning add-ons to<br />
purchase or to carry around.<br />
The integral sampling system<br />
allows for measurements of dew<br />
point to be made at pressure,<br />
up to 20 barg, with an option<br />
available to measure up to 300<br />
barg. The integrated filter removes<br />
particulates down to 0.3μm which<br />
provides 99.5% protection to the<br />
sensor.<br />
The<br />
fast-responding<br />
polymer moisture sensor of the<br />
MDM50 gives rapid dew-point<br />
measurements in compressed air –<br />
T95 to -35°C from ambient typically<br />
in less than 5 minutes.<br />
The sensing element is highly<br />
stable, resistant to contamination<br />
and, along with the robust and<br />
sturdy case, this means the<br />
hygrometer is well-suited to<br />
the often tough conditions in<br />
industrial applications.<br />
A long battery life is essential<br />
for making measurements in the<br />
field, especially in locations where<br />
there is limited access to charging<br />
points, so the MDM50 portable<br />
hygrometer has an operation<br />
time of 16 hours on one full<br />
charge. This means users have the<br />
confidence that they can work all<br />
day without having to stop taking<br />
measurements for charging.<br />
A universal charger is included<br />
with the unit and stored in its case,<br />
for when not in use.<br />
As well as dew point in<br />
compressed/instrument-air<br />
dryers, typical applications for<br />
the MDM50 include moisture<br />
measurements in medical gases,<br />
polymer chip and the output from<br />
refrigerated dryers.<br />

Protect analogue camera<br />
systems with 3-in-1 surge<br />
arrester<br />
Factors including low cost,<br />
compatibility with other<br />
components, a wide range of<br />
video signals and the protection<br />
of existing systems have made<br />
certain that analogue CCTV<br />
cameras are still widely used.<br />
A compact arrester ensuring<br />
the protection and availability of<br />
video transmission systems, the<br />
DEHNvario 3in1 surge arrester<br />
guarantees unrestricted operation<br />
of analogue camera and video<br />
transmission systems, even<br />
during thunderstorms.<br />
Representing a new<br />
generation of arresters that<br />
protects different signals of<br />
power supply and information<br />
technology systems, the<br />
DEHNvario stands out due<br />
to its extremely flexible<br />
connection technology. This<br />
complete solution protects<br />
three interfaces in a single<br />
device: the supply voltage; data<br />
interface; and video signal. This<br />
largely eliminates an incorrect<br />
selection of devices.<br />
The DEHNvario 3in1<br />
solution is ideally suited for<br />
analogue cameras that require:<br />
• Power feed<br />
• RS485 feed (pan, tilt, zoom<br />
functions);<br />
• and analogue video signals<br />
feed (BNC).<br />
With its high discharge<br />
capacity of up to 5 kA (8/20 µs)<br />
per core, it can be used according<br />
to the lightning protection zone<br />
concept at the boundaries from<br />
0B to 2 and higher.<br />

Compact, space saving safety light curtains<br />
deTec4 Prime: WE TAKE SAFETY TO THE NEXT LEVEL.<br />
The introduction of the deTec4<br />
As the inventors of the original safety light curtain, we have accumulated over half a century‘s worth of experience<br />
and expertise in all things safety. And what do we do with that experience? We continue to innovate – so<br />
our customers can take it to the next level. We used our expertise to create the deTec4 Prime: Versatile thanks<br />
Core to its fl exible and connection concept. deTec2 Freely positionable with optimal Core resistance to interference. safety<br />
Extremely easy<br />
to use with a visualized display. And a minimum of connection work when cascaded systems are needed.<br />
It’s a masterpiece based on the original. We think that’s intelligent. www.sick.com/deTec4<br />
light curtains made protecting<br />
hazardous points and access<br />
points easier than ever. Now, the<br />
newest member of the family,<br />
the deTec4 Prime, is taking this<br />
technology one step further.<br />
The new deTec4 Prime safety<br />
light curtain builds upon the<br />
successful concept of the deTec4<br />
Core. At the same time, it combines<br />
the features of existing light<br />
curtain variants in one device and<br />
adds even newer functionalities.<br />
All of this in the compact, spacesaving<br />
design of the Core version.<br />
Thanks to a brilliantly simple<br />
cloning plug design, the basic<br />
variants can be configured to suit<br />
the application requirements in<br />
no time at all using four variably<br />
interchangeable plugs. Inserting<br />
the plug is all it takes: The deTec4<br />
Prime then switches to detection<br />
mode and the operator confirms<br />
the change, establishing the<br />
configuration.<br />
The deTec4 safety light curtains<br />
are electro-sensitive protective<br />
devices that comply with<br />
performance level “e” in accordance<br />
with EN ISO 13849, and SIL3 in<br />
accordance with IEC 61508.<br />
With 150-millimeter divisions,<br />
the deTec safety light curtains offer<br />
13 different protective field heights<br />
from 300 to 2100 mm.<br />
All the variants in the deTec<br />
product family are available with<br />
14 mm and 30 mm resolution;<br />
safety light curtains with 14 mm<br />
resolution are used in every<br />
application that requires a reliable<br />
means of keeping fingers away<br />
from the system.<br />
Metal and plastic components<br />
are combined in the impact<br />
resistant housing so that deTec<br />
safety light curtains stand up to<br />
the hardest requirements with no<br />
problem.<br />
Thanks to their advanced shock<br />
resistance and their extremely<br />
rugged front windows, reliable<br />
functions are assured even under<br />
extreme conditions.<br />
Heat, cold, and humidity are<br />
no match for deTec safety light<br />
curtains:<br />
They meet the requirements<br />
of enclosure ratings IP 65 and IP<br />
67, are approved for an operating<br />
temperature range of -30 °C to +55<br />
°C – and are even able to ensure that<br />
processes take place efficiently<br />
and safely when temperatures are<br />
in the freezing range.<br />
The new deTec4 Prime: advanced<br />
functionality based on<br />
an original design<br />
The deTec product family<br />
offers the right solution for every<br />
application. The deTec4 stands<br />
out as an all-around talent. Due to<br />
its flexible connection concept,<br />
it covers almost all standard<br />
applications.<br />
Perhaps best described as a<br />
form of standardized intelligence,<br />
its flexible M12 connectivity<br />
enables the deTec4 Prime to<br />
provide the right solution every<br />
time in a whole host of applications.<br />
This keeps down the number of<br />
variants available to a considerable<br />
degree and saves costs.<br />
Making diverse requirements<br />
manageable<br />
Through its modular concept,<br />
the deTec4 Prime has managed<br />
to pack a whole range of different<br />
device types into just 26 variants<br />
and provide the customer with<br />
functional options.<br />
This means that plant<br />
manufacturers or operators<br />
can keep the basic length and<br />
resolution variants that are relevant<br />
to their plant concepts in stock,<br />
and have a flexible way of simply<br />
bolting on additional functions<br />
using four different system plugs,<br />
as and when required. Building<br />
blocks for grown-ups: Functions<br />
provided via four system plugs<br />
Restart interlock, external<br />
device monitoring, and a binary<br />
status output are the optional<br />
functions available for the deTec4<br />
Prime safety light curtain.<br />
The 8-pin system plug variant<br />
is able to cover all three functions<br />
without the need for additional<br />
wiring – and it is even possible to<br />
create cascaded systems with very<br />
few connection requirements.<br />
Up to three protective fields<br />
may be positioned adjacent<br />
to one another without blind<br />
zones, providing a simple way of<br />
establishing presence detection.<br />
Four system plugs are available<br />
for the configuration of desired
9<br />
<strong>19.5</strong><br />
required functions. Configuration<br />
is done without software. This<br />
simplifies storage and reduces<br />
costs.<br />
The integrated beam coding<br />
prevents any interference from<br />
other safety light curtains in the<br />
immediate vicinity, with the coding<br />
set using a DIP switch on the plug –<br />
no tools are necessary.<br />
Fast commissioning via integrated<br />
visual laser and alignment<br />
display<br />
All deTec4 safety light curtains<br />
save commissioning time and<br />
costs thanks to their integrated<br />
LEDs and diagnostic functions.<br />
The exact adaptation of the range<br />
during commissioning is done<br />
automatically by the de-Tec4<br />
itself – the integrated alignment<br />
display guarantees faster and more<br />
reliable positioning of the sender<br />
and receiver using 4 LEDs, as well as<br />
automatic calibration of the range<br />
up to 21 m at 30 mm resolution.<br />
The sender and receiver can be<br />
configured from one side.<br />
On both sides, the colours of the<br />
monitoring and diagnostic LEDs<br />
– red, yellow, and green – indicate<br />
the status of the device. Four blue<br />
LEDs on the receiver, meanwhile,<br />
provide clear information about<br />
the signal strength.<br />
Flexible plant integration without<br />
blind zones<br />
Thanks to the innovative FlexFix<br />
mounting bracket, it is possible<br />
to mount all deTec safety light<br />
curtains on a variety of machine<br />
types in a matter of minutes. The<br />
mounted light curtain can be<br />
rotated before it is finally secured<br />
in the FlexFix mounting bracket,<br />
and thus ensures a continuous<br />
protective field up to the ends of the<br />
housing.<br />
Maximum performance thanks<br />
to extensive sensing range<br />
At 21 m, the deTec4 Prime<br />
demonstrates more than twice<br />
the sensing range of the rest of the<br />
product family. With a resolution<br />
of 30 mm, this therefore provides<br />
reliable protection for even<br />
exceptionally wide machines.<br />
And thanks to the integrated<br />
laser alignment aid, adjusting the<br />
system takes no time.<br />
Using deflection mirrors with<br />
these safety light curtains are also<br />
extremely straightforward.<br />
Simply more<br />
Users have already been<br />
pleased with the consistently<br />
well-designed accessories that<br />
are available for the entire deTec<br />
family – ranging from mounting<br />
brackets and cables to local reset<br />
switches, mirror columns, and<br />
protective field extensions, all the<br />
way through to a replacement<br />
adapter for upgrades involving<br />
a deTec light curtain without<br />
rewiring.<br />
Forward thinking in safety<br />
Whether in the automotive,<br />
parts supplier, packaging<br />
industries or in machine building<br />
and plant construction, the<br />
sustainability of functional<br />
safety technology is shown<br />
in two important points: fast<br />
commissioning and significantly<br />
faster system effectiveness thanks<br />
to flexible design options and<br />
continuous production, and thus<br />
higher system efficiency.<br />
The concept of the new deTec4<br />
Prime safety light curtain opens<br />
up a more complex range of<br />
possibilities while making them<br />
much easier to handle.<br />
Over a half-century of<br />
accumulated experience and<br />
expertise in regards to safety<br />
has led to the creation of the<br />
deTec4 Prime and with it the new<br />
benchmark for versatility and<br />
operating comfort.<br />

Programmable time switch technology for temperature<br />
control<br />
This new generation of<br />
programmable time switch<br />
technology encompasses<br />
AlphaRex³ and MicroRex time<br />
switches for precise temperature<br />
control in domestic, commercial<br />
and industrial environments.<br />
Rex time switches, with<br />
analogue and digital dials, are<br />
ideally suited for OEM’s and panel<br />
builders who can pre-programme<br />
the time switch during installation.<br />
At a later stage when the panel or<br />
product is connected to power,<br />
all the end-user has to do is set the<br />
real time. These programmable<br />
time switches ensure high clock<br />
precision, optimum reliability,<br />
maximum safety and enhanced<br />
aesthetics.<br />
In temperature control<br />
applications, these devices are<br />
used to switch an electric circuit<br />
on or off at selected times during<br />
a pre-programmed time period.<br />
These time switches also have an<br />
automatic return facility and a<br />
permanent forced switching on or<br />
off override control.<br />
Typical applications for time<br />
switches in heating and cooling<br />
installations include water heaters,<br />
air conditioners, heating and<br />
ventilation systems and swimming<br />
pool heaters.<br />
AlphaRex³ programmable<br />
time switches have a userfriendly<br />
standardised text guided<br />
programming facility, with a high<br />
resolution digital display and<br />
backlight. There is a standard,<br />
single data key for all devices in<br />
this range to allow quick and easy<br />
transfer of programmes to other<br />
time switches and for creating back<br />
up copies.<br />
These time switches are<br />
available with standard and<br />
multiple functions, with a daily or<br />
weekly programme facility and a<br />
clock working reserve of six years.<br />
Programming with clock<br />
precision to the second is<br />
controlled directly on the time<br />
switch, or outside the distribution<br />
board using a PC and Legrand’s<br />
AlphaSoft programming software.<br />
Other features include an EEPROM<br />
memory which prevents settings<br />
being lost and the facility to<br />
programme the clock prior to<br />
despatch. Once the unit has been<br />
programmed, the information will<br />
remain installed even if the switch<br />
is not connected to power. The<br />
battery can be removed without<br />
having to uninstall the time switch<br />
from the distribution board.<br />
MicroRex time switches offer<br />
easy plug and play installation for<br />
daily and weekly programming.<br />
By simply setting the analogue<br />
switching dial during start up, the<br />
time is automatically set using<br />
the fast-run mode. In the event<br />
of a power failure, the time is<br />
automatically reset.<br />
MicroRex analogue and<br />
digital modules are 24 hour and<br />
seven day time switches for DIN<br />
rail and wall mounting, with a 100<br />
hour running reserve. These units<br />
have the capability for multiple<br />
programmes, which ensures<br />
optimum time setting flexibility.<br />
MicroRex time switches have an<br />
LED status indicator, a precision<br />
clockwork of 0.2 s/day and are<br />
controlled by either a quartz or<br />
synchronous motor. For increased<br />
safety and user convenience, there<br />
is an automatic and manual and<br />
advance/over-ride facility.<br />
An analogue defrost switch<br />
is available for short periods of<br />
controlled defrosting. The timer<br />
<strong>19.5</strong><br />
can repeat one or two settable<br />
short programmes within 24 hours<br />
and the defrosting time is from one<br />
to 60 minutes per contact.<br />
Other time switches in the<br />
Legrand range are designed<br />
for precise control in security<br />
installations – for access points;<br />
electric fences and alarms –<br />
as well as for use in industrial<br />
installations, including pump<br />
stations, filters and conveyors.<br />
Legrand time switches are also<br />
used for the lighting of commercial<br />
boards and signage, as well as for<br />
street lighting. Time switches in<br />
agricultural applications are used<br />
for irrigation and sprinkler systems<br />
and for cyclical programmes, like<br />
animal feed systems.<br />

VA purgemeters with surface passivation for trace-level<br />
analysis<br />
The option of surface<br />
passivation for trace-level<br />
analysis is now offered for the For<br />
its variable area flow meters DK<br />
32, DK 34 and DK 37.<br />
Trace-level analysis is used for<br />
providing evidence of very small<br />
concentrations in the range of ppm<br />
(parts per million) to ppb (parts per<br />
billion).<br />
Here, it is very important that<br />
none of the particles to be detected<br />
are already adsorbed in the sample<br />
feed line as this would lead to a<br />
delayed or even wrong analysis<br />
result.<br />
Examples are the<br />
measurement of H2S content in<br />
natural gas or oil, mercury, or NOx/<br />
SOx flue gas analysis in various<br />
industries.<br />
To avoid adsorption, sample<br />
feed lines, fittings and valves can be<br />
surface passivated.<br />
This can now also be applied<br />
to the DK 32, DK 34 and DK 37 allmetal<br />
purgemeters that are used<br />
for adjustment and monitoring of<br />
the sample flow to the analyser.<br />
Before being assembled and<br />
calibrated, all metal components<br />
in contact with the medium such<br />
as cone, float, valve components,<br />
etc., receive a SilcoNert 2000 inert<br />
silicon coating, a patented surface<br />
treatment at a temperature of<br />
400°C / 752°F.<br />
The same is possible for wetted<br />
metal components of DK 46, DK 47,<br />
DK 48 and DK 800 glass devices.<br />

New powerful switched-mode power supply with an<br />
enormous power reserve<br />
These power supplies provide<br />
an excellent power reserve of<br />
50 percent for up to four seconds<br />
to cope with short current loads.<br />
Instead of an inrush current<br />
limitation with a simple NTC<br />
element, charging the capacitors<br />
of the new switched-mode power<br />
supplies is micro-processor<br />
controlled. This ensures an ideal<br />
start-up of the voltage supply.<br />
The voltage supply is ensured<br />
for several milliseconds if the mains<br />
voltage briefly fails, e.g. caused by<br />
switching operations in the supply<br />
network.<br />
These switched-mode power<br />
supplies provide the specific<br />
nominal power across the entire<br />
temperature range. Derating only<br />
has to be taken into account above<br />
an operating temperature of 60 °C.<br />
<strong>19.5</strong><br />
All 24 V switched-mode<br />
power supplies are equipped with<br />
double terminals. This simplifies<br />
wiring and provides more clarity<br />
in the control cabinet. Innovative<br />
technology means the new power<br />
supplies require considerably less<br />
space in the panel, as compared to<br />
common cabinet power supplies.<br />

Space-saving<br />
wiring up to<br />
10 mm²<br />
Wire conductors up to 10 mm²<br />
in a confined space with the<br />
new UT 6-3L three-level terminal<br />
block.<br />
Thanks to the function shaft on<br />
each level, up to three potentials<br />
can be distributed in one terminal<br />
housing.<br />
The conductors are connected<br />
using the maintenance-free screw<br />
connection principle. All terminal<br />
points can be marked individually,<br />
thereby ensuring very clear<br />
arrangement of the wired terminal<br />
strip.<br />
Power ratings of up to 1000 V<br />
and 50 A can be wired with the new<br />
three-level terminal block.<br />
Since this terminal block<br />
also has all the system features of<br />
the CLIPLINE complete terminal<br />
block system, standard system<br />
accessories can be used. This<br />
reduces the logistics costs for the<br />
user.<br />

Pneumatic energy saving solutions suitable for all factory<br />
environments<br />
The 3-port 3-position power<br />
valve VEX3, used to control<br />
actuators has been modified,<br />
allowing for improved cost<br />
savings and versatility by offering<br />
greater energy efficiency and<br />
added handling flexibility thanks<br />
to the addition of new manual<br />
override options, which have<br />
been added to the existing nonlocking<br />
push type.<br />
The new 3/3 way VEX3 series<br />
features additional benefits to the<br />
existing conventional 2/2 way,<br />
3/2 way and 5/3 way Power Valves.<br />
Compared to its predecessor, the<br />
VEX3 is not only smaller in size, but<br />
when added to the existing benefit<br />
of fewer components required per<br />
circuit, it delivers on space and cost<br />
savings.<br />
Achieving a flow rate of up<br />
to 3300 l/min, the VEX3, with its<br />
three positions, makes it possible<br />
to perform intermediate stops of<br />
cylinders up to 125 mm bore size or<br />
to change the speed of cylinders up<br />
to 200 mm bore size.<br />
What’s more, two valves can<br />
be connected to a double acting<br />
cylinder, controlling speeds,<br />
slow stopping, acceleration and<br />
deceleration with nine different<br />
valve position combinations.<br />
While the functions of the VEX3<br />
can be performed by an electric<br />
actuator, this new Power Valve<br />
offers customers greater force and<br />
flexibility while being more cost<br />
efficient to purchase and operate.<br />
Further savings are achieved in<br />
vacuum applications when suction<br />
or release of the workpiece is not<br />
required, as the power valve can<br />
be set to the intermediate position<br />
where there is no air movement<br />
and energy is not being wasted.<br />

Lid integrity inspection with 3D vision sensor<br />
When it comes to metal<br />
closures in packaging,<br />
nothing can be left to chance:<br />
In products such as jam jars,<br />
the consumer goods industry<br />
requires seals to be tight and jars<br />
to be hermetically sealed.<br />
Anyone who makes their<br />
own jam will know that a small<br />
indentation in the lid is the key<br />
to creating the perfect vacuum.<br />
However, this small feature is<br />
difficult to identify by eye in<br />
industrial production contexts<br />
involving high numbers of parts<br />
and high speeds.<br />
Fynbo Foods A/S, a leading<br />
Danish manufacturer of jams,<br />
preserves, and fruit spreads, uses<br />
the TriSpector1000 3D vision<br />
sensor on its Vraa production lines<br />
to check the integrity of seals. As a<br />
manufacturer for the organic and<br />
fair markets, Fynbo Foods stands<br />
for healthy, sustainable products<br />
that conform to high standards of<br />
quality.<br />
That was why the company<br />
needed to find a reliable inspection<br />
solution for quality inspections on<br />
its sealed jars. Once the jam has<br />
been successfully pasteurized,<br />
the lid has a small indentation as a<br />
result of the vacuum created in the<br />
process.<br />
If pasteurization goes wrong,<br />
on the other hand, the lid will have<br />
a slight bulge. Only tight lids can<br />
prevent pressure compensation<br />
from taking place.<br />
The TriSpector’s role is to<br />
identify any minor deviations in the<br />
lid surface.<br />
The TriSpector1000 inspects<br />
two jars each second; faulty goods<br />
are then ejected from the process.<br />
“We tested out a range of other<br />
solutions.<br />
The TriSpector is the only one<br />
that is able to do the job perfectly.<br />
What’s more, it’s easy to use – when<br />
I installed additional devices, I<br />
was able to simply copy across the<br />
configuration,” explains Jesper Juul<br />
Nielsen, an electrician at Fynbo<br />
Foods.<br />

Reduce downtime – find leakage currents without taking<br />
equipment offline<br />
Fluke has launched the Fluke<br />
368 & 369 true-RMS leakage<br />
current clamp meters that help<br />
users detect, document, record<br />
and compare leakage current<br />
Power hub revamped<br />
readings over time as a means of<br />
preventing unplanned downtime,<br />
and identifying intermittent GFCI<br />
(Ground Fault Circuit Interrupter)<br />
and RCD (Residual Current<br />
Device) trips, all without taking<br />
equipment off line.<br />
The Fluke 368 has a large<br />
(40mm diameter) jaw for work<br />
with large conductors. The clamp’s<br />
jaw is fully shielded to accurately<br />
capture very small leakage<br />
signals, and to minimize external<br />
electromagnetic interference.<br />
The device allows users to track<br />
changes in leakage current over<br />
time, helping to identify potential<br />
problems before they turn into<br />
major failures.<br />
Product features:<br />
• True-RMS measurements<br />
for accuracy when measuring<br />
complex, non-sinusoidal<br />
waveforms<br />
• 40 mm jaw opening<br />
• Highest resolution of 1 μA,<br />
measure up to 60 A<br />
• Selectable filter function<br />
removes unwanted noise<br />
• Max/Min/Average readings<br />
and hold function<br />
• Forward-facing LED worklight<br />
for use in dark wiring cabinets<br />
• Backlit display; auto backlight<br />
off and auto power off for<br />
extended battery life<br />
• CAT III 600V safety rating<br />
• Internal Memory Logging: up<br />
to 65,000 measurement points<br />
Designed specifically for<br />
industrial electricians and facilities<br />
maintenance technicians, the 368<br />
& 369 are invaluable for general<br />
purpose electrical maintenance,<br />
as well as preventative and<br />
predictive<br />
maintenance<br />
and fault troubleshooting.<br />
Specific applications include<br />
maintenance tests on motors and<br />
transformers and current leakage<br />
measurements for installation<br />
tests.<br />

Segment Coupler 3 with PROFINET<br />
gateway and advanced diagnostics.<br />
Gateway can be configured via<br />
web interface or FDT/DTM frame<br />
No sooner has digital<br />
communication arrived in<br />
the process industry than the<br />
next technological revolution is<br />
around the corner. PROFIBUS DP<br />
is now regarded as an established<br />
standard that is tried and tested<br />
and has become commonplace<br />
in many process plants.<br />
PROFINET goes one crucial step<br />
beyond.<br />
This is not a complete<br />
reinvention of the wheel, nor is it a<br />
revolution that brings everything<br />
that has gone before into question.<br />
In fact, PROFINET uses the same<br />
tried-and-tested technologies that<br />
proved themselves with PROFIBUS<br />
DP. Evolution would therefore be<br />
a more appropriate term for this<br />
than revolution. Similarly, plant<br />
operators are presented with<br />
good opportunities to gradually<br />
move into the future and to rely<br />
on future-proof infrastructure<br />
components for modernizations<br />
and new installations with the<br />
PROFINET gateway.<br />
PROFINET is basically an<br />
industrial Ethernet variant that<br />
has been specifically expanded<br />
to include the PROFIBUS DP<br />
functionality and has already<br />
become extremely well<br />
established in factory automation.<br />
This allows communication at<br />
the control level to be integrated<br />
seamlessly into the rest of<br />
the company's IT landscape.<br />
Communication with PROFIBUS PA<br />
at the field level is implemented via<br />
PROFINET gateways.<br />
The specially defined proxy<br />
technology enables simple<br />
and practical integration of bus<br />
systems established in process<br />
automation such as PROFIBUS PA.<br />
From Big Data to the Internet<br />
of Things<br />
There is another reason why<br />
PROFINET is the way to the future.<br />
In a process plant, intelligent field<br />
devices generate large volumes of<br />
data. However, a large part of this<br />
data is currently still untapped. This<br />
data can easily be converted into<br />
concretely useful information via<br />
big data solutions. The information<br />
is then available anywhere via<br />
Ethernet-based systems, opening<br />
up a wealth of new applications<br />
that are only just beginning to<br />
emerge. The strict separation<br />
between the IT environment<br />
and industrial automation has<br />
made consistent use of this data<br />
considerably more difficult, since<br />
the transparency of the process<br />
plant does not go beyond the<br />
control center. PROFINET is the key<br />
to eliminating such limitations.<br />
Significantly Reduced Complexity<br />
A consistently homogeneous<br />
system is of course much less<br />
complex than a heterogeneous<br />
environment consisting of<br />
specialized system landscapes.<br />
PROFINET is ideal for eliminating<br />
the previously strict separation<br />
between the automation<br />
environment and IT. The field level<br />
still communicates according<br />
to the proven protocols,<br />
standards, and technologies,<br />
while gateways create the direct<br />
connection to an industrial<br />
Ethernet-based control level. The<br />
manufacturers of infrastructure<br />
components have recognized<br />
this development trend and are<br />
increasingly starting to prepare<br />
their solutions for the PROFINET<br />
environment. Pepperl+Fuchs is<br />
one of the pioneers of innovative<br />
technologies for hazardous areas.<br />
Power Hub with PROFINET<br />
Gateway<br />
The Power Hub concept is one<br />
of their core technologies. The<br />
company has now thoroughly<br />
overhauled this concept and put<br />
the entire product family on a<br />
new foundation. The keywords<br />
here are: extremely compact<br />
design, different redundancy<br />
concepts, and, for the first time,<br />
a PROFINET gateway. The fact<br />
that line redundancy and the S2<br />
system redundancy of PROFINET<br />
are supported is particularly<br />
interesting.<br />
The latter is based on the<br />
principle that a gateway is<br />
connected to two separate masters<br />
via separate communication<br />
paths. The result is a highavailability<br />
system without the<br />
need for additional hardware. If<br />
one communication path fails<br />
due to a cable break, the second<br />
path is automatically used and<br />
communication is maintained.<br />
PROFINET also offers system<br />
redundancy for high-availability<br />
communication with up to four<br />
communication paths. As soon as<br />
control systems are available that<br />
allow R2 system redundancy, this<br />
solution will also be offered.

Transparent Communication in<br />
a Compact Format<br />
It is always crowded in<br />
the switch cabinet. The latest<br />
generation of the Power Hub<br />
solution further reduces the form<br />
factor of its components. For<br />
example, the previous Segment<br />
Couplers 2 and 3 have been<br />
replaced with a new model.<br />
This requires less space while<br />
offering significantly enhanced<br />
functionality. The new basic<br />
Segment Coupler replaces the<br />
previous Segment Coupler 1. It<br />
is only 20 mm wide and thus four<br />
times smaller than the previous<br />
solution.<br />
Pepperl+Fuchs therefore now<br />
currently offers the most compact<br />
fieldbus power supply on the<br />
market, and with unprecedented<br />
energy efficiency. Up to four<br />
fieldbus segments can be<br />
connected.<br />
This reduces the number<br />
of switch cabinets. Because<br />
of the low power dissipation,<br />
active air conditioning is not<br />
required, further improving the<br />
energy performance and system<br />
availability as a whole. The fieldbus<br />
segments also require significantly<br />
less engineering and installation<br />
work.<br />
Remote Configuration and<br />
Explosion Safety<br />
The new Power Hub<br />
allows remote configuration<br />
and diagnostics via a device<br />
type manager or web server.<br />
Configuration tools for integration<br />
into virtually any automation<br />
Windows 10 for panel PCs<br />
The Embeddedline family of<br />
panel PCs is now equipped<br />
with the modern Windows 10<br />
Enterprise operating system.<br />
Windows Embedded Standard<br />
7 is available as an alternative. If<br />
applications are not approved<br />
for this operating system, the<br />
Windows 7 Professional standard<br />
operating system can be used.<br />
Phoenix Contact is also<br />
adding further functions to the<br />
system are also available.<br />
The advanced diagnostic<br />
module enables the Power Hub to<br />
be incorporated into the ongoing<br />
monitoring of the physical fieldbus<br />
level. Of particular interest for the<br />
chemical industry is the option<br />
of an intrinsically safe power<br />
supply for Zone 0 – 2 (Division 1/2)<br />
hazardous areas and field devices<br />
according to the Ex ia, Ex ib, and Ex<br />
ic types of protection.<br />
In conjunction with the<br />
high-power trunk concept, the<br />
Power Hub allows an intrinsically<br />
safe power supply to the<br />
instrumentation according to IEC<br />
60079-11—and for a large number<br />
of end devices, even if they are<br />
connected via long cable runs.<br />
The DART technology is<br />
available as an alternative. This<br />
effectively prevents ignitable<br />
sparks in hazardous areas. Due to<br />
the high active power available,<br />
DART provides the intrinsically<br />
safe high-power trunk, the ideal<br />
combination of achievable cable<br />
length, multiple devices, and<br />
safety.<br />
PROFINET ensures that<br />
technical development never<br />
stops. It does not take much<br />
imagination to envision a possible<br />
scenario in the near future: a field<br />
level networked using PROFIBUS<br />
PA that communicates with the<br />
Ethernet-based PROFINET control<br />
level via gateways.<br />

<strong>19.5</strong><br />
The Internet of Things is more than a vision<br />
After automating its processes,<br />
the Swiss chemical distributor<br />
Brenntag Schweizerhall has found<br />
an entirely new business model.<br />
Basel (Switzerland) is a<br />
stronghold of the chemical<br />
industry. This explains why the<br />
demand for primaries and base<br />
materials such as sulfuric acid,<br />
hydrochloric acid and caustic<br />
soda is so great in that region.<br />
One important supplier of these<br />
products is Brenntag Schweizerhall<br />
AG, whose warehouse and<br />
distribution centre in the ‘Infrapark<br />
Baselland’ is in the immediate<br />
neighbourhood of its customers.<br />
The company asked<br />
Endress+Hauser to automate its<br />
plant and at the same time ordered<br />
a logistics concept guaranteeing<br />
ultimate safety and efficiency from<br />
storage right through processing<br />
to the delivery of products. Today,<br />
the site features a totally new<br />
infrastructure with storage tanks<br />
and blending units, plus a pipeline<br />
network which allows Brenntag<br />
Schweizerhall to supply its<br />
customers directly. “Until recently,<br />
we carried about 30,000 tonnes of<br />
hazardous materials by truck to our<br />
customers every year.<br />
This resulted in relatively high<br />
transportation costs,” explains<br />
Wolfram Heymann, CEO of<br />
Brenntag Schweizerhall. “Our<br />
aim was to optimise the supply<br />
chain, not only commercially,<br />
but also with regards to safety on<br />
site because the corresponding<br />
loading and unloading operations<br />
were no longer required.”<br />
For this reason, it was not<br />
only the automation of the<br />
manufacturing process that<br />
was highlighted. The logistics<br />
and commercial processes were<br />
also scrutinised. Working closely<br />
with Brenntag Schweizerhall,<br />
Endress+Hauser synchronised the<br />
data flow along the value-added<br />
chain and the data exchange<br />
between the actual process<br />
control system and the customer’s<br />
ERP system. Today, the central<br />
business processes between all<br />
stakeholders can be handled in a<br />
common network.<br />
“The cross-system access to<br />
information enhanced efficiency<br />
and effectiveness helping us to<br />
make severe cutbacks on data<br />
administration costs,” says Roger<br />
Jaggi, Head of Engineering<br />
Solutions at Endress+Hauser<br />
Switzerland. “At the same time, we<br />
wanted to keep plant operation<br />
as simple and easy as possible.”<br />
The controls were programmed<br />
and set up for the customer<br />
using tried and tested standard<br />
components. Personnel operate<br />
the plant via software that<br />
provides graphic visualisation<br />
of the process. One important<br />
interface is Endress+Hauser’s<br />
software, SupplyCare: the platform<br />
for inventory management<br />
relies on the appropriate sensor<br />
technology in the tanks to monitor<br />
replenishment and deadline<br />
scheduling, also allowing the<br />
full visualisation of stocks and<br />
inventories on the screen – both on<br />
site at the operating stations and at<br />
the headquarters in Basel. Thanks<br />
to the networked supply chain,<br />
Brenntag Schweizerhall can now<br />
keep stocks low and avoid delivery<br />
bottlenecks.<br />
Using the fast links of the local<br />
fibre optic network, end customers<br />
today report their requirements<br />
directly to the control system<br />
– without the red tape in order<br />
handling, and with the automated<br />
inventory management ensuring<br />
that the tanks and warehouses are<br />
always sufficiently full. “No matter<br />
how much the customer requests –<br />
thanks to automation, the product<br />
can now be supplied efficiently,<br />
safely and on time in the desired<br />
quantity and degree of dilution,”<br />
says Roger Jaggi.<br />
The direct access to device<br />
and process data using a browserbased<br />
solution also makes<br />
maintenance and service work<br />
easier, with the latest device<br />
status called up in next to no time.<br />
Endress+Hauser’s experts are<br />
capable of remote monitoring<br />
maintenance intervals or of<br />
responding to error messages<br />
while en route.<br />
Thanks to the online access<br />
to all data and documents, the<br />
source of the error or malfunction<br />
is quickly identified. The customer<br />
is automatically notified in the<br />
event of maintenance work or a<br />
change in product availability.<br />
The close collaboration between<br />
Endress+Hauser and Brenntag<br />
Schweizerhall from the planning<br />
stage to commissioning, pays<br />
dividends. “Procurement is a great<br />
deal easier today.<br />
We’ve optimised warehouse<br />
capacities, increased flexibility<br />
in production and cut logistics<br />
costs,” summarises Wolfram<br />
Heymann. “Now we not only<br />
have an automated warehouse<br />
for chemical base materials, we<br />
also have a totally new business<br />
model where all our customers<br />
and suppliers are integrated in a<br />
common network.”<br />
The modern plant not only<br />
safeguards efficient and timely<br />
deliveries to end customers – it<br />
has also become safer thanks to<br />
the pipeline system. CEO Wolfram<br />
Heymann: “The integrated<br />
solution has allowed us 1,500<br />
hazardous goods transports off the<br />
road – and to eliminate all related<br />
loading and unloading processes.”<br />
Market leader<br />
Brenntag Schweizerhall AG is<br />
the Swiss offspring of the Brenntag<br />
group of companies, the global<br />
leader in chemical distribution.<br />
In 2007 the company evolved<br />
from the merger of Christ Chemie<br />
AG, Chem-On Vertriebs AG and<br />
Schweizerhall Chemie AG and<br />
employs around 250 staff at four<br />
sites. Brenntag Schweizerhall<br />
operates in the market with three<br />
business divisions: industrial<br />
chemicals, specialty chemicals<br />
(nutrition and health) and waste<br />
disposal.<br />
Safe processes<br />
The raw chemicals are supplied<br />
by pipeline, rail or truck and<br />
stored. Flowmeters (A) measure<br />
the quantities. Endress+Hauser<br />
instruments<br />
continually<br />
monitor levels in all tanks (B) and<br />
temperature sensors and overfill<br />
prevention systems provide safety.<br />
The mixing process in the blender<br />
(C) is automated.<br />
Flow and temperature<br />
measurements provide the basics<br />
and density and conductivity<br />
parameters increase process<br />
safety. Customers in the<br />
neighbourhood are supplied via<br />
pipelines, with trucks used when<br />
needed. Flowmeters (D) measure<br />
the quantities handled.<br />

Load sensing valve<br />
The SALAMI VDP08 load sensing<br />
valve is ideal for a wide range<br />
of applications, mainly in the<br />
mobile field, where independent<br />
flow control of actuators is<br />
needed without being affected<br />
by load variations, and offers<br />
good metering characteristics<br />
that provide increased energy<br />
saving.<br />
With the high-quality features<br />
SALAMI products is renowned<br />
for, the valve offers a more costeffective<br />
solution than competitor<br />
products, and is easily retrofitted<br />
without having to change<br />
mounting specifications.<br />
The valve can be used in<br />
applications up to 130 l/min, and a<br />
maximum working pressure of 350<br />
bar.<br />
This sectional directional<br />
control valve type has become<br />
Easy lifting products<br />
popular in the industry, owing<br />
to the simplicity of the design,<br />
high tolerance and ability to<br />
function under extreme operating<br />
conditions and its excellent<br />
controllability.<br />
In addition, the many control<br />
positioning options available to<br />
the operator eliminates the need<br />
to add auxiliary components and<br />
additional pipe connections.<br />
Other benefits of the valve<br />
include its modular design.<br />
In the case of a malfunctioning<br />
valve section, the design feature<br />
means that only the faulty section<br />
needs to be replaced, and this can<br />
be done on site without having to<br />
remove the entire valve.<br />
This also means a much more<br />
versatile solution that allows users<br />
to expand the valve configuration,<br />
should the need for more machine<br />
functions arise.<br />
The VDP08 load sensing valve<br />
can be ordered for use with both<br />
variable and fixed displacement<br />
pump applications.<br />

Inline analyser system for edible oil and fat processing<br />
Introducing the OPTIQUAD-EOF<br />
4050 W for the continuous inline<br />
measurement of free fatty acids<br />
(FFA), total polar material (TPM),<br />
peroxide value (POV), moisture<br />
or dirt.<br />
The optical spectroscopic<br />
analyser system is aimed at frying<br />
and other edible oil as well as fat<br />
applications.<br />
OPTIQUAD-EOF 4050 W<br />
measures directly in the pipe:<br />
analysis is achieved via an optical<br />
window mounted in a standard<br />
VARINLINE measuring section. The<br />
readings of FFA, TPM, POV moisture<br />
or dirt are provided instantly for<br />
process control or dynamic control<br />
loops via four 4...20 mA outputs.<br />
Depending on the application,<br />
measurement of anisidine value<br />
(AV) and iodine value (IV) are<br />
possible.<br />
Compared to conventional<br />
laboratory methods used to obtain<br />
these values, OPTIQUAD-EOF 4050<br />
W reduces the need for sampling,<br />
sample transport and handling,<br />
and the associated sources of error<br />
and costs.<br />
The optical spectroscopy<br />
analyzing method allows for a<br />
wide range of use in edible oil<br />
applications, such as oil extraction,<br />
oil refinement and frying processes<br />
up to oil recycling, as well as fat<br />
processing.<br />
For example, the continuous<br />
inline measurement of FFA content<br />
in frying oil helps to minimize the<br />
addition of fresh oil: the FFA value<br />
can be kept below a defined limit<br />
whilst allowing to maintain a high<br />
level of quality.<br />
It also provides a wide<br />
measuring range, e.g. 0…98% for<br />
FFA, and an accuracy of RMSEp:<br />
±0,03% up to ± 1% FFA, depending<br />
on the measurement range.<br />
OPTIQUAD-EOF 4050 W<br />
spectroscopic analysis system<br />
consists of the analyser unit<br />
(protection rating IP65/NEMA4X)<br />
and the operating unit, an<br />
industrial PC with touch screen<br />
display for parameterisation and<br />
automatic calibration in a stainless<br />
steel housing (IP65/NEMA4X),<br />
optionally built into a switch<br />
cabinet.<br />
It uses up to four measuring<br />
methods (transmission, scattering,<br />
fluorescence and refraction)<br />
with up to 12 wavelengths<br />
from ultraviolet to infrared.<br />
The underlying calibration is<br />
calculated automatically from<br />
reference data specific to the<br />
application. OPTIQUAD-EOF 4050<br />

Predictive maintenance with wireless tools<br />
It’s the foundation of any<br />
electrical safety program:<br />
limiting the exposure of workers<br />
to the electrical hazards of shock<br />
and arc flash.<br />
Using test leads and clamps<br />
to probe inside a live panel when<br />
troubleshooting and performing<br />
routine maintenance always<br />
exposes workers to danger.<br />
Electrical personal protective<br />
equipment (PPE) is a last line of<br />
defense and must never be relied<br />
upon as the primary method<br />
of protecting electricians and<br />
technicians.<br />
Safe work practices, including<br />
the use of non-contact test tools<br />
that do not require electrical<br />
workers to place themselves<br />
in harm’s way, must first be<br />
considered when it comes to<br />
electrical safety.<br />
Fluke Connect®, introduced<br />
in 2014, added a new level<br />
of efficiency and effective<br />
collaboration for maintenance<br />
and troubleshooting, in all kinds of<br />
manufacturing, commercial, and<br />
retail facilities.<br />
Technicians can monitor real<br />
time results from more than 20<br />
different Fluke test tools from a<br />
smart phone (up to 10 at a time<br />
on iPhone and 6 on Android).<br />
This information can also be<br />
securely shared, in real time, with<br />
authorized team members in other<br />
locations.<br />
In addition, test results and<br />
maintenance data can be collected<br />
through the Fluke Connect app<br />
and stored by asset in secure Fluke<br />
Cloud storage. That means that<br />
troubleshooting and maintenance<br />
staff can access that data in the field<br />
to compare new measurements<br />
to baseline measurements to<br />
more quickly identify problems.<br />
The end result is that technicians<br />
can use Fluke Connect to quickly<br />
identify and diagnose problems<br />
while securely sharing the related<br />
data, when they want and with the<br />
specific people they have given<br />
permission to view it.<br />
Fluke’s newly released clamp<br />
meters - the Fluke 376 FC True<br />
RMS AC/DC Clamp Meter with<br />
iFlex and the Fluke 902 FC Truerms<br />
HVAC Clamp Meter allow the<br />
technicians to access tight places<br />
and work around large, awkward<br />
conductors and can transmit<br />
measurements to a smartphone<br />
or tablet for later, detailed analysis.<br />
Those measurements can be<br />
uploaded to the cloud.<br />
Technicians can combine<br />
measurement data from multiple<br />
Fluke Connect test tools to create<br />
and share reports from the job site<br />
via email and collaborate in real<br />
time with other colleagues with<br />
ShareLive video calls or email,<br />
increasing productivity in the field.<br />
The 376 and 902 clamp meters<br />
also decrease the frequency that<br />
technicians will need to wear<br />
personal protective equipment<br />
when working on high voltage/<br />
current panels.<br />
Technicians simply turn off<br />
the panel, verify the panel is deenergized<br />
using standard safety<br />
procedures, place the clamp<br />
and sync it to a smartphone with<br />
the Fluke Connect app, close<br />
the panel, reenergize it, and<br />
take measurements from a safe<br />
distance.<br />
The Fluke 376 FC True-rms AC/<br />
DC Clamp Meter with iFlex<br />
features:<br />
• Integrated VFD LowPAS filter<br />
for low driver measurements<br />
• True RMS voltage and current<br />
for non-linear signals<br />
• Measureable to 1000Amps DC<br />
and > 25 000Amps AC<br />

The world’s toughest liquid analysis systems<br />
Some liquid analytics are<br />
conducted in the toughest<br />
conditions in the world -<br />
mining, precious metal and ore<br />
refinement and extreme chemical<br />
processes, where most sensors<br />
are unable to provide accuracy or<br />
longevity.<br />
Deterioration in the accuracy<br />
of sensors creates costly wastage<br />
as process control is affected.<br />
Additionally, in these extreme<br />
environments many sensors<br />
require intensive maintenance<br />
and frequent calibration, which<br />
are time consuming and costly<br />
processes.<br />
Improved measurement accuracy<br />
and process control<br />
Turtle Tough sensors are<br />
designed to provide accurate<br />
measurement for significantly<br />
longer than any other sensor.<br />
Custom made to provide lower<br />
rates of expiration, slower accuracy<br />
degradation and reduced fouling,<br />
the sensors are reported to provide<br />
massive savings to customers<br />
from better accuracy and tighter<br />
process control.<br />
Maintenance free<br />
All Turtle Tough pH, ORP,<br />
Conductivity and Ion Selective<br />
measurement sensors have no<br />
serviceable components. This<br />
means completely maintenance<br />
free operation - for the entire life of<br />
the sensor.<br />
A truly superior sensor must be<br />
impervious to ingress. Turtle Tough<br />
sensors are solid state and totally<br />
sealed for life. Not only will they<br />
resist process contamination but<br />
they are completely maintenance<br />
free. There is no gel or electrolyte<br />
to be refilled, no reference to<br />
replace and no o-rings or seals to be<br />
compromised or replenished.<br />
Longest life in the industry<br />
Turtle Tough sensors<br />
boast significantly extended<br />
replacement intervals, reducing<br />
the time and manpower required<br />
to replace and install sensors.<br />
Rather than a one size fits all<br />
approach, each sensor is optimised<br />
for its intended process use, with<br />
various salt mixtures and polymer<br />
formulations. The proprietary pH<br />
glass and ORP elements provide<br />
unmatched performance in harsh<br />
environments.<br />
By utilising solid-state<br />
conductive reference junction<br />
polymers the manufacturers<br />
are able to achieve accurate<br />
measurement while resisting<br />
process contamination into the<br />
reference system.<br />
This ability to maintain high<br />
ionic conductivity while resisting<br />
aggressive gas intrusion is what<br />
makes these sensors outlast<br />
virtually all competitors in difficult<br />
process control conditions.<br />
Intelligently designed for extreme<br />
applications<br />
Turtle Tough’s patented<br />
and advanced technology<br />
will revolutionise the way you<br />
experience liquid analysis.<br />
The entire range of pH, ORP,<br />
Conductivity, Dissolved Oxygen<br />
and Ion Specific sensors are<br />
designed to be physically and<br />
chemically superior providing long<br />
life and high performance in the<br />
world’s toughest environments.<br />
Sensors have been developed that<br />
are optimised for high hydrofluoric<br />
acid, saturated sodium, high<br />
sulphide, organic solvents, high<br />
cyanidation, ultrapure water, high<br />
temperature and slurry/viscous<br />
applications.<br />
Turtle Tough analysers<br />
The TT-MA Analysers have<br />
been designed specifically to<br />
interface with the extreme Turtle<br />
Tough sensors to provide the<br />
maximum possible service life to<br />
the sensor.<br />
The unique modular design<br />
enables you to create a full<br />
multi-parameter analyser with<br />
any combination of different<br />
analytical modules including<br />
pH, ORP, Dissolved Oxygen,<br />
Conductivity and Ion Specific.<br />
Functional modules can also be<br />
added including digital MODBUS,<br />
Data-logging and Relays. The<br />
TT-MA analyser family are the<br />
most economical full feature<br />
industrial analysers available in the<br />
marketplace, often at a fraction of<br />
the cost of other analysers.<br />

A new radar level sensor for water-supply and sewage<br />
systems<br />
The VEGAPULS WL S 61 radar<br />
sensor is ideal for all simple<br />
applications in the water-supply<br />
and sewage sectors.<br />
Featuring a wide range<br />
of mounting options, it is an<br />
especially cost-effective radar<br />
solution, because it can be<br />
readily integrated into existing<br />
infrastructure.<br />
Just as with the VEGAPULS WL<br />
61, which has been available for<br />
several years with a large installed<br />
base, the new VEGAPULS WL S 61<br />
offers a design optimized for use<br />
in the water-supply and sewage<br />
sectors.<br />
Radar technology offers<br />
numerous advantages compared<br />
with ultrasonic sensors, which<br />
used to be standard in this sector;<br />
radar is independent of weather<br />
influences, strong sun, wind, fog or<br />
rain.<br />
In addition, no compensation<br />
is needed for variations in the<br />
signal transmission time due to<br />
air temperature fluctuations.<br />
With an accuracy of +/- 5 mm, the<br />
VEGAPULS WL S 61 covers a wide<br />
range of applications.<br />
This sensor is particularly<br />
suitable for level and flow<br />
measurement in water treatment<br />
plants. Its excellent focusing<br />
enables its use in pumping stations<br />
and rainwater overflow basins,<br />
for flow measurement in open<br />
channels, and for level monitoring.<br />
The sensor’s robust housing is<br />
wear and maintenance-free, and<br />
its high degree of protection,<br />
IP 68 (2 bar), also makes it<br />
suitable for applications where<br />
<strong>19.5</strong><br />
the sensor may be temporarily<br />
submerged. The unit complies<br />
with the latest LPR standard (Level<br />
Probing Radar), and is approved for<br />
open-air use without restrictions<br />
or special attachments.<br />
An entirely new feature is<br />
Bluetooth wireless operation from<br />
a smartphone or tablet (and/or a PC<br />
with PACTware) when combined<br />
with a Bluetooth USB adapter;<br />
this makes commissioning<br />
and diagnosis even simpler.<br />
Corresponding display and signal<br />
processing units enable the display<br />
of measurements and provide the<br />
relay outputs needed, for example,<br />
to control a pump.<br />

Under high pressure…<br />
The type MAN-U diaphragm<br />
differential pressure gauges<br />
have been specifically designed<br />
to be both cost-efficient and<br />
flexible. The instruments, used to<br />
check filter obstructions, pressure<br />
drops, flow rate differences, level<br />
measurements and generally<br />
the difference between two<br />
pressures of equal or different<br />
circuits, are available for a variety<br />
of measuring ranges from 0 ... 100<br />
mbar to 0 ... 25 bar differential<br />
pressure. The effective measuring<br />
system with a double diaphragm<br />
is suitable for gaseous and liquid<br />
media, to be used in processes<br />
up to 200 bar static pressure<br />
and withstand temperatures of<br />
up to 150° C. Even one-sided<br />
overpressure levels of up to 200<br />
bar can be tolerated thanks to a<br />
special barrier.<br />
A large range of options allows<br />
individual and exact setting of<br />
the differential pressure gauge to<br />
match the relevant application and<br />
medium. Of course, the gauges<br />
can also be designed for process<br />
control with switch contacts. In<br />
addition, designs with suitable<br />
damping fluids allow its use in the<br />
case of strong pressure surges<br />
and vibrations. When connected<br />
to suitable pressure mediation<br />
lines, the measuring devices can<br />
also be installed away from the<br />
process itself. The pressure gauges<br />
are securely protected with topquality<br />
stainless steel housing in<br />
sizes of 100 and 150 mm with FKM<br />
and PTFE seals, and are also suitable<br />
for use with aggressive media.<br />
The large and easy-to-read<br />
display on an aluminium scale<br />
is located behind a cover made<br />
of specially hardened glass.<br />
Alongside devices with a front<br />
ring for integration into panels,<br />
there are suitable designs for<br />
process-suited mounting on<br />
walls or pipelines, including<br />
the corresponding mounting<br />
accessories.<br />

New AC power supply with integrated energy storage<br />
Control valve<br />
now available<br />
in ANSI Class<br />
600 and PN 63<br />
The new uninterruptible power<br />
supplies (USP) from the TRIO<br />
product range for the DIN rail<br />
reliably supply AC loads with up<br />
to 750 VA/600 W.<br />
The power supply is for 230<br />
V AC and 120 V AC applications.<br />
Thanks to the integrated USB<br />
interface, high-level devices can<br />
be connected to it. In this way, any<br />
industrial PCs connected to the<br />
power supply can be shut down in a<br />
controlled way. The pure sine curve<br />
at the output enables a seamless<br />
transition, as the sine generated in<br />
battery operation runs in sync with<br />
the mains previously used for the<br />
supply.<br />
Since a UPS module and<br />
energy storage are combined in<br />
one housing, the power supply<br />
is particularly space-saving. The<br />
integrated VRLA energy storage<br />
ensures long buffer times and can<br />
<strong>19.5</strong><br />
be extended with a further energy<br />
storage unit. Supplying loads from<br />
the energy storage is possible, even<br />
without mains input. The device<br />
also has LED status indicators for<br />
signaling and function monitoring,<br />
as well as active 24 V DC switch<br />
outputs for forwarding to a higherlevel<br />
control system.<br />

Accurate measurements for process control and product<br />
quality of LNG<br />
Natural gas is sourced from<br />
various gas fields and offers a<br />
major leap towards a renewablebased<br />
energy future.<br />
Colourless, odourless and nontoxic,<br />
it is the cleanest-burning<br />
hydrocarbon on the market today,<br />
with global demand on the rise.<br />
It is used for both heat and<br />
power, and the automotive market<br />
has also embraced it to keep<br />
vehicles on the road.<br />
The majority of natural gas is<br />
transported in gaseous form via<br />
onshore or offshore gas pipelines.<br />
For stranded gas reserves where<br />
there is little or no local demand,<br />
or for long transport distances –<br />
more than 1000km offshore or less<br />
than 3000km onshore - it becomes<br />
more economical to liquefy the<br />
natural gas prior to transportation,<br />
especially as it ensures safe and<br />
easy storage to its various locations.<br />
In addition, due to the nearly<br />
600-fold reduction in volume for<br />
liquid natural gas (LNG) versus<br />
natural gas, LNG is often the<br />
preferred method for local storage.<br />

operation – the gas pre-treatment,<br />
dehydration, and liquefaction<br />
process trains – is essential to<br />
ensure on-time LNG loading and<br />
shipment.<br />
In addition, processing feed<br />
gas to remove contaminants is<br />
critical to the operation of LNG<br />
plants. Raw natural gas from<br />
different geological formations<br />
contains varying amounts of acid<br />
gases (H2S and CO2).<br />
These<br />
contaminants<br />
must be removed from LNG<br />
feed gas to prevent CO2<br />
from freezing at cryogenic<br />
processing temperatures and<br />
H2S from exceeding gas quality<br />
specifications.<br />
Once LNG has been liquefied<br />
and stored in tanks, it is ready for<br />
transport to other markets, usually<br />
via LNG carrier. These custody<br />
transfers from the storage tank<br />
to the ship, or from the ship at a<br />
receiving terminal, often involve<br />
millions of rands of product in a<br />
single shipment.<br />
As such, it is essential that<br />
both the deliverer and recipient of<br />
the LNG know exactly how much<br />
energy has been transacted, and<br />
an uncertainty of as little as one<br />
percent in energy transferred can<br />
cost the buyer or seller dearly. The<br />
compositional measurements<br />
of natural gas in gaseous and<br />
liquefied states, and of mixed<br />
refrigerants, help LNG plants<br />
operate efficiently and determine<br />
the energy value of LNG. According<br />
to the Group International des<br />
Importateurs de Gaz Naturel<br />
Liquéfié (GIIGNL), a key factor<br />
in determining proper energy<br />
transfer is the measurement of<br />
gross calorific value (GCV), which is<br />
calculated from LNG composition.<br />
For traditional GC-vaporiser<br />
systems, it is essential to eliminate<br />
partial and pre-vaporisation for all<br />
LNG flow rates of the LNG sample,<br />
which requires careful installation<br />
and proper maintenance to ensure<br />
good insulation and no hot spots<br />
in the sample vaporisation and<br />
transport paths.<br />
In addition, the GIIGNL<br />
states that LNG must be sampled<br />
during stable flow of LNG. Data<br />
collected during flow variations<br />
and interruptions is not used<br />
in the calculation of the energy<br />
transferred, and can result in a<br />
significant amount of LNG being<br />
transferred without known GCV.<br />
Laser spectroscopy analysers<br />
from SpectraSensors have the<br />
technology to perform critical<br />
measurements throughout<br />
the LNG value chain - from pretreatment<br />
and liquefaction<br />
through to custody transfer and<br />
regasification to support on-time<br />
shipments. Its tuneable diode<br />
laser absorption spectroscopy<br />
analysers (TDLAS) monitor H2O,<br />
H2S and CO2 concentrations in<br />
natural gas as the gas undergoes<br />
treatment to remove and control<br />
these contaminants prior to<br />
liquefaction.<br />
Furthermore, SpectraSensors<br />
Raman Optograf LNG analysers<br />
perform on-line composition<br />
measurements of feed gas, LNG<br />
as a cryogenic liquid, mixed<br />
refrigerant, and gas following LNG<br />
regasification.<br />
A unique feature of the<br />
Optograf LNG analyser is that<br />
it measures the composition<br />
of LNG in the cryogenic liquid<br />
state, resulting faster update<br />
times because it does not<br />
require any vaporisation, sample<br />
conditioning, or sample transport.<br />
The Optograf LNG analyser is<br />
essentially immune to LNG flow<br />
variations, and so can provide a<br />
more complete measurement<br />
of the GCV of the entire shipload.<br />
Maintenance is also significantly<br />
lower with the Optograf LNG<br />
analyser, since there is no moving<br />
parts and no insulation to degrade.<br />
LNG that has been delivered<br />
to an import terminal may be<br />
however too rich or too lean to<br />
meet local pipeline specifications<br />
of the downstream markets to<br />
which the gas will be delivered.<br />
There are several ways to modify<br />
the CV of the natural gas. The CV can<br />
be reduced by adding N2 or CO2,<br />
or by selectively removing C3/C4<br />
components from the sample.<br />
The CV can be increased by<br />
mixing with liquefied petroleum<br />
gas (LPG) or natural gas liquids<br />
(NGL). And, in some cases, LNG with<br />
different CVs can be blended to<br />
achieve target quality.<br />
Measurement of the CV of<br />
the final mixture is essential to<br />
confirming that the product<br />
quality meets local regulations to<br />
avoid significant tariffs. The Wobbe<br />
Index (WI), which is calculated from<br />
the gas composition, is the most<br />
widely accepted measure of gas<br />
quality and interchangeability.<br />
The Optograf LNG analyser<br />
provides<br />
composition<br />
measurement of the LNG, WI,<br />
and simultaneously provides the<br />
concentration of nitrogen, which<br />
can be used to ensure that nitrogen<br />
levels do not exceed pipeline<br />
specifications.<br />
WI modification of natural<br />
gas at import terminals is often<br />
measured with a Process GC. Prior<br />
to analysis, the LNG sample must<br />
be vaporised.<br />
Poor repeatability in<br />
vaporisation leads to large<br />
variations in WI, adding<br />
uncertainty to the ballasting<br />
process. In addition, vaporisation<br />
and sample transport lag time,<br />
coupled with typical Process<br />
GC update times of four to five<br />
minutes, means that this approach<br />
provides only sporadic updates<br />
during ballasting, increasing the<br />
likelihood of overshooting the WI<br />
target, and incurring additional<br />
cost.<br />
Because the Optograf LNG<br />
analyser is able to measure the<br />
sample in the cryogenic liquid,<br />
response times are much faster and<br />
repeatability is much higher than<br />
with legacy GC/ vaporiser systems.<br />
As demand grows, LNG export<br />
facilities will need to handle<br />
natural gas feeds of varying quality<br />
from multiple sources, and so<br />
adjust refrigerant composition<br />
to ensure the lowest energy<br />
consumption during liquefaction.<br />
In addition, these plants will need<br />
to dynamically compensate for<br />
refrigerant losses with makeup<br />
refrigerant. The technology<br />
from SpectraSensors measures<br />
both natural gas and make-up<br />
refrigerant composition in both<br />
the gas and liquid phases, so plant<br />
operators can measure the quality<br />
of the feed gas and thus adjust their<br />
make-up refrigerant for optimum<br />
plant operating efficiency.<br />

Precise, hygienic and dynamic switching and control from<br />
electromotive diaphragm valves<br />
<strong>19.5</strong><br />
The Type 3323 shut-off valve<br />
and the Type 3363 control<br />
valve are two new additions to<br />
a line of electromotive valves,<br />
which – especially for applications<br />
without a compressed air supply –<br />
set new standards with respect to<br />
performance, reliability and costeffectiveness.<br />
The valves with an<br />
electromotive actuator are ideal<br />
for applications that either do not<br />
require compressed air or for which<br />
compressed air is not available due<br />
to the difficulty of conveying it to<br />
the application.<br />
They feature high control<br />
accuracy and highly dynamic<br />
control, which allows them to<br />
reach the set point exactly and<br />
instantaneously with dynamic<br />
performance of 4 mm/s.<br />
The maximum closing time<br />
is below 4.5 s. Overshooting or<br />
undershooting, which can occur<br />
with pneumatic valves, is not<br />
possible. Integration of the piloting<br />
function in the compact drive<br />
eliminates the need for control<br />
cabinet installation, as well as field<br />
piping and the power supply for<br />
the compressed air.<br />
The electromotive drive<br />
principle allows adaptation of<br />
the driving force to the respective<br />
application, which increases<br />
the life of the diaphragms and<br />
maintenance intervals, thus<br />
reducing maintenance costs.<br />
Safety is the top priority<br />
The electromotive drives<br />
can be combined with diverse<br />
standard bodies and diaphragms<br />
of the family of pneumatically<br />
operated products. Electromotive<br />
valves are very cost-effective due to<br />
their low energy costs and savings<br />
throughout the entire system.<br />
A special advantage of the this<br />
solution is an innovative cogging<br />
torque controller, which fixes<br />
the position of the valve without<br />
additional energy consumption.<br />
If there is a power outage the<br />
safety position can be approached<br />
via the optional SAFEPOS energy<br />
storage pack. The safety position<br />
can also be adapted to the<br />
particular process. A mechanical<br />
position indicator with a 360° LED<br />
clearly indicates the position and<br />
status of the valve at all times.<br />
Hygienic, high-quality and<br />
durable<br />
The field bus capable Type<br />
3323 / 3363 diaphragm valves<br />
consist entirely of high-quality<br />
components.<br />
The linear motion is executed<br />
by a brushless DC motor with a<br />
planetary gear via a low-friction,<br />
permanently lubricated ball screw.<br />
This also prevents negative effects<br />
from pressure surges, which occur<br />
in pneumatic drives.<br />
Precise control with segment disc valves<br />
Segment disc valves work on<br />
a very simple but effective<br />
principle. The central throttling<br />
elements – the segment discs<br />
that glide and seal against each<br />
other – are positioned in the valve<br />
body perpendicular to the flow<br />
direction.<br />
On a non-rotatable aligned<br />
segment disc whose geometry<br />
determines the flow rate and<br />
characteristic, a movable disc<br />
having the same number<br />
of segments is shifted by a<br />
tangentially engaging rod in such<br />
a way that the free cross-sectional<br />
area of the segments changes<br />
continuously.<br />
Regardless of the prevailing<br />
pressure difference, a spring<br />
assembly constantly presses the<br />
movable disc onto the fixed disc.<br />
As a result, the flow direction is<br />
variable and the valve can be<br />
installed in any position.<br />
This special design makes<br />
segment disc valves one of the<br />
few valves that combine control<br />
precision even in extreme<br />
operating conditions with a<br />
high seal tightness and very low<br />
exposure to wear.<br />
Segment disc valves and<br />
Segment disc orifices<br />
Perfect and variable control<br />
with high precision over a wide<br />
flow range is made possible by the<br />
segment disc valves from Schubert<br />
& Salzer.<br />
Due to the robust design and<br />
the reciprocal flow direction,<br />
segment disc valves are suitable<br />
The robust powder-coated<br />
aluminium body with protection<br />
type IP65/IP67 features an easy-toclean<br />
and closed design. The shutoff<br />
and control valves are resistant<br />
to weather, impacts and vibrations,<br />
which makes them ideal for use in<br />
harsh environments.<br />
Ideal for hygienic applications<br />
The new electromotive<br />
diaphragm valves are offered as<br />
a shut-off valve (Type 3323) and<br />
as a control valve (Type 3363),<br />
in diameters up to DN50. The<br />
FDA, USP and EHEDG compliant<br />
valves are especially suitable for<br />
cleanroom, filling, packaging<br />
and CIP/SIP applications in the<br />
pharmaceutical and health care<br />
sectors, for use in the dairy and<br />
cosmetics industries, as well as for<br />
industrial water treatment. When<br />
pressurised air is not available or<br />
not wanted, electromotive valves<br />
are ideal.<br />
For valves that are operated<br />
remotely from the central air<br />
supply, the operational costs can<br />
be reduced. The superior control<br />
characteristics are another benefit<br />
of electromotive actuators.<br />

Compact block valve series – the next generation<br />
The new and, at the same time,<br />
smallest of the five actuator<br />
The new and, at the same time,<br />
smallest of the five actuator sizes of<br />
the iComLine® is setting standards<br />
in the area of miniature valve<br />
designs.<br />
This valve size offers a flow<br />
capability of 2.0 litres per minute,<br />
whilst the height of the pneumatic<br />
actuator is scarcely larger than the<br />
diameter of a 2 euro coin.<br />
The small area of 20 x 20 mm is<br />
setting new standards in the area of<br />
ultra pure pneumatic valves.<br />
Developed primarily for<br />
customers from the chemical and<br />
semiconductor industries, the<br />
iComLine® product line can now<br />
cover a wide range of uses.<br />
With a focus on process<br />
equipment, in addition to<br />
providing a compact design and<br />
high resistance to media, the<br />
iComLine® series also makes it<br />
possible to use valves as a multifunctional<br />
unit in the form of a<br />
multi-port valve block.<br />
Various actuator and<br />
connection options, as well<br />
as a corresponding range of<br />
accessories, are also available.<br />
These options, coupled with<br />
the performance capability of the<br />
valves, open up numerous new<br />
areas of use.<br />
The new actuator size<br />
enables the valves to be used for<br />
applications in semiconductor<br />
production, laboratory and<br />
process analytics, as well as in the<br />
manufacturing of energy storage<br />
systems.<br />
The visual design and<br />
necessary operating parameters<br />
are identical to all other valves in<br />
the GEMÜ iComLine® series.<br />

New multifunction measuring tool for all professionals in HVAC<br />
and industry<br />
The AMI 300 is a new<br />
multifunction instrument<br />
which is a key measuring tool<br />
for all professionals in HVAC and<br />
industry. The unit can measure up<br />
to 6 parameters simultaneously<br />
for pressure, temperature (RTD,<br />
thermocouple, NTC), humidity,<br />
air quality, air velocity and airflow,<br />
and tachometry.<br />
Some 12 000 values can be<br />
stored and then restored on PC<br />
through wireless communication.<br />
The AMI has a large 70 x 50 mm<br />
display (with bargraph) which<br />
allows quick reading of results and<br />
browsing is easy via a joystick on<br />
the keypad.<br />
The wireless probes are<br />
supplied with a multifunction<br />
key to allow measurement and<br />
settings.<br />
A large choice of probes are<br />
available such as vanes with<br />

Wide light band facilitates reliable detection of both small<br />
and large objects<br />
Featuring a wide light band,<br />
the Leuze RK 46C.DXL VarOS<br />
retro reflective sensor is able to<br />
reliably detect both small and<br />
large objects.<br />
Objects can be round, angular<br />
or both, with glossy surfaces, have<br />
transparent shrink wrapped film<br />
or even be totally black, with gaps<br />
or with high ambient light levels.<br />
These Leuze sensors are ideal for<br />
when the objects to be detected<br />
or the associated environmental<br />
conditions deviate from the norm.<br />
The Leuze RK 46C.DXL<br />
VarOS retro reflective sensor is<br />
particularly effective in this regard<br />
as it responds to objects with the<br />
entire width of its light band, which<br />
gives it the capability to be able to<br />
handle interruptions.<br />
The wide light band allows for<br />
detection over a 45 mm to 60 mm<br />
wide area<br />
The sensitivity and/or<br />
resolution of the sensor can be<br />
adjusted easily by means of a<br />
button located on the rear housing.<br />
And this Leuze sensor features a<br />
handy ‘teach me’ function which<br />
allows it to be adapted easily<br />
between two object sizes greater<br />
than 8 mm at the touch of a button.<br />
This ensures optimum flexibility of<br />
application.<br />
The use of this sensor does<br />
away with the need for expensive<br />
light barriers or multiple individual<br />
sensors.<br />
Other features include the<br />
ability to calibrate for detection<br />
of transparent, perforated or<br />
small objects as well as the ability<br />
to reliably detect even with<br />
depolarising media such as foil<br />
packaging.<br />

Testing spring operated<br />
pressure safety valves in situ<br />
The PreVenTest is a robust,<br />
but ingeniously built system<br />
for testing all types and sizes of<br />
spring operated pressure safety<br />
valves ‘In-Situ’, in process and<br />
under the normal operating<br />
conditions. The portable system<br />
enables you to proof the correct<br />
working and performance or<br />
identify PSV’s in need of repair/<br />
maintenance without plant shutdown.<br />
The ‘In-Situ’ PreVenTest<br />
system is standard equipped with<br />
industrial laptop and is available in<br />
two versions; the fully automatic<br />
PreVenTest Advance (optionally<br />
available in intrinsically safe / ATEX<br />
certified version) and the ultralight,<br />
battery driven and handcontrolled<br />
PreVenTest LTC.<br />
Both the Advance and LTC are<br />
suitable for the same extended<br />
range up to 20 kN and completed<br />
with computer registration. The<br />

New absolute pressure<br />
transmitter with different<br />
measuring ranges<br />
As of now, ifm has added<br />
absolute pressure sensors<br />
to its versatile portfolio in the<br />
pressure sensor range.<br />
The new PT05 series with<br />
robust metal measuring cell, G<br />
1/4 process connection, M12<br />
connector and analogue output is<br />
available in the common pressure<br />
ranges up to 10 bar.<br />
Absolute pressure sensors<br />
operate independently of the<br />
surrounding air pressure; that is<br />
what distinguishes them from<br />
sensors working on a relative<br />
measurement principle.<br />
The measurement is not<br />
influenced by weather and<br />
altitude-related fluctuations of air<br />
pressure. This is often a decisive<br />
factor in vacuum applications,<br />
which require a fine pressure<br />
control.<br />
Absolute pressure sensors do<br />
not require ventilation, therefore<br />
incorrect measurement due to a<br />
blocked exhaust is impossible. In<br />
the field of pressure sensors the<br />
new units stand out as specialists<br />
for ”specific duties“.<br />

New sensor generation for 3-dimensional object measurement<br />
Wenglor has developed<br />
sensors that can scan and<br />
evaluate objects in 3 dimensions.<br />
This generation of 70 models<br />
of the weCat3D Profile Sensors<br />
allows data to be either read out<br />
directly as measured values or<br />
used for rapid further processing<br />
of the point cloud.<br />
3 D calculation of volume is of<br />
great value in industries such as<br />
food, machinery manufacturing,<br />
woodworking, electronics,<br />
automotive and pharmaceutical<br />
where precise compliance<br />
to weight and geometric<br />
specifications measurements are<br />
demanded.<br />
More than 12 million<br />
measuring points per second.<br />
The weCat3D series works with<br />
a visual field width within a range<br />
of 30 to 1300 mm in the horizontal<br />
X-axis and is capable of detecting<br />
differences in height of just 2.0 µm<br />
within the Z working range at a<br />
rate of 3.6 to 12 million measuring<br />
points per second. Available laser<br />
classes (1, 2M, 3R, 3B) and two<br />
selectable types of light (red, blue)<br />
result in a diverse product portfolio<br />
of more than 70 models.<br />
Two performance classes and a<br />
thousand possibilities<br />
With a weight of just 300 g and<br />
a space-saving housing of 90 x<br />
36 x 64 mm), the model weCat3D<br />
MLSL scans as many as 3.6 million<br />
measuring points/sec, has an<br />
output range of up to 4000 Hz, as<br />
well as a resolution of down to 22<br />
µm in visual field width X and down<br />
to 3.3 µm in working distance Z.<br />
The model weCat3D MLWL<br />
scans up to 12 million measuring<br />
points/sec, has an output rate of up<br />
to 6000 Hz, visual field widths from<br />
30 to 1300 mm and high resolution<br />
down to 17 µm in visual field width<br />
X and down to 2.0 µm in working<br />
distance Z.<br />
Due to this extremely high<br />
resolution in the Z and X directions,<br />
the sensors can detect the smallest<br />
components in the micron range<br />
such as those used in PCB assembly.<br />
The special algorithms allow<br />
the sensors to generate powerful<br />
measuring signals and top quality<br />
profile data that is not even<br />
impaired by glossy, reflective<br />
surfaces such as metals.<br />
The high dynamic range<br />
ensures that objects can be<br />
precisely measured almost<br />
independent of colour and<br />
brightness.<br />

Controllable single-use diaphragm valve<br />
Introducing the world’s first<br />
controllable single-use<br />
diaphragm valve, the GEMÜ<br />
SUMONDO. The product range<br />
now comprises a manually<br />
operated version alongside a<br />
pneumatically operated solution.<br />
The trend towards simplified<br />
upstream and downstream<br />
plant designs and the<br />
effective prevention of crosscontamination<br />
risks means that<br />
single-use disposable technology<br />
is becoming an increasingly<br />
high-profile and important field<br />
– especially in pharmaceutical<br />
process engineering.<br />
Single-use design is<br />
increasingly being used<br />
particularly in the manufacture<br />
of smaller batch sizes, which are<br />
required, for example, in research<br />
and pilot plants.<br />
GEMÜ SUMONDO links the<br />
valve body and actuator together<br />
using a defined process. After the<br />
application process, only the valve<br />
body is removed, the actuator itself<br />
can be reused repeatedly in the<br />
plant.<br />
The valve body is manufactured<br />
from polypropylene in a cleanroom<br />
and is gamma-sterilizable up to<br />
50 kGy. It isolates the working<br />
medium hermetically from<br />
the environment and from the<br />
actuator via a welded diaphragm.<br />
The internally welded diaphragm<br />
protects the medium from the<br />
environment not only during<br />
operation, but also after removal of<br />
the valve body.<br />
The major advantage of<br />
GEMÜ SUMONDO in comparison<br />
to conventional pinch valves lies<br />
in the precise controllability of<br />
processes. Using a tried and tested<br />
actuator design from conventional<br />
plant engineering, a high degree<br />
of flexibility and reliability can be<br />
achieved.<br />
The manually operated version<br />
has an optical position indicator as<br />
standard.<br />
The new actuator is<br />
manufactured from high-grade<br />
plastic. It is gamma-sterilizable and<br />
washable.<br />
An autoclavable version is<br />
planned for the first six months<br />
of 2017. The process for selecting<br />
the valve body is identical to that<br />
for the pneumatically operated<br />
version.<br />

Versatile and low cost pressure sensors<br />
The tried and tested principle<br />
of a thick-film ceramic<br />
measuring cell ensures great<br />
reliability from the compact<br />
and versatile type SEN-98/-99<br />
pressure sensors .<br />
This pressure sensor meets the<br />
highest of performance demands<br />
by virtue of its robust construction,<br />
overpressure safety properties, as<br />
well as temperature stability and<br />
good reproducibility.<br />
The unit’s overload protection<br />
limit is dependent on the<br />
measurement range, of which<br />
there are 31, running from -1...0<br />
bar to 0...600 bar relative pressure<br />
or from 0…1 to 0…25 bar absolute<br />
pressure. There is a choice of 4...20<br />

Wide light band facilitates<br />
reliable detection of both<br />
small and large objects<br />
Featuring a wide light band,<br />
the Leuze RK 46C.DXL VarOS<br />
retro reflective sensor is able to<br />
reliably detect both small and<br />
large objects.<br />
Objects can be round, angular<br />
or both, with glossy surfaces, have<br />
transparent shrink wrapped film<br />
or even be totally black, with gaps<br />
or with high ambient light levels.<br />
These Leuze sensors are ideal for<br />
when the objects to be detected<br />
or the associated environmental<br />
conditions deviate from the norm.<br />
The Leuze RK 46C.DXL VarOS retro<br />
reflective sensor is particularly<br />
effective in this regard as it<br />
responds to objects with the entire<br />
width of its light band, which gives<br />
it the capability to be able to handle<br />
interruptions.<br />
The wide light band allows for<br />
detection over a 45 mm to 60 mm<br />
wide area<br />
The sensitivity and/or<br />
resolution of the sensor can be<br />
adjusted easily by means of a<br />
button located on the rear housing.<br />
And this Leuze sensor features a<br />
handy ‘teach me’ function which<br />
allows it to be adapted easily<br />
between two object sizes greater<br />
than 8 mm at the touch of a button.<br />
This ensures optimum flexibility<br />
of application. The use of this<br />
sensor does away with the need for<br />
expensive light barriers or multiple<br />
individual sensors.<br />
Other features include the<br />
ability to calibrate for detection<br />
of transparent, perforated or<br />
small objects as well as the ability<br />
to reliably detect even with<br />
depolarising media such as foil<br />
packaging.<br />

Valve solutions for the solar energy industry<br />
All signs are pointing towards<br />
growth in the solar energy<br />
sector. The world market for<br />
the operation and servicing of<br />
photovoltaic power stations<br />
will see significant growth in<br />
the coming years. According<br />
to various studies, the installed<br />
capacity is set to triple worldwide<br />
by 2020.<br />
Valve solutions for the solar<br />
energy industry<br />
On account of the variety of<br />
processes, process media and the<br />
associated supply and disposal<br />
systems, a wide range of different<br />
solutions are required for the<br />
individual production steps in the<br />
area of valves, measurement and<br />
control systems. This is primarily<br />
due to the different quality and<br />
purity requirements as well as the<br />
flow rates required.<br />
The materials range from<br />
polypropylene (PP) and poly<br />
vinylidene fluoride (PVDF) to ultra<br />
pure and resistant perfluoroalkoxy<br />
(PFA). As well as various plastics,<br />
components made of stainless<br />
steel are also used depending on<br />
the process step.<br />
GEMÜ is able to cover this<br />
broad range of requirements<br />
comfortably with its extensive<br />
product range.<br />
In addition to standard<br />
solutions, customers can also<br />
be provided with individual,<br />
customized solutions thanks to<br />
the perfectly coordinated modular<br />
system.<br />
Depending on the valve<br />
required, GEMÜ offers various<br />
function and actuation types.<br />
Completely metal-free equipment<br />
and valves that are manufactured<br />
in the in-house cleanroom plant in<br />
Switzerland are also available.<br />
Innovative valves for a variety<br />
of applications<br />
The GEMÜ iComLine series is<br />
based on the globe valve design,<br />
has a cavity-filled design and<br />
boasts a long service life. The<br />
main advantage is the compact<br />
design and the resulting low space<br />
requirement. This can be further<br />
optimized by using what are<br />
referred to as block solutions. In<br />
this case, the iComLine valves are<br />
combined to form multi-functional<br />
valve blocks.<br />
In addition to the individual<br />
valves, further components such as<br />
sensors, check valves or electrical<br />
position indicators can also be<br />
integrated into these applicationspecific<br />
units.<br />
Another innovative product is<br />
the GEMÜ CleanStar "solar valve".<br />
This diaphragm valve, which<br />
also features the tried and tested<br />
GEMÜ seal system, impresses with<br />
its high quality and performance<br />
capability.<br />
Thanks to its cavity-filled<br />
design and the various types of<br />
design, it is suitable for a variety<br />
of processes in the solar energy<br />
industry. The SmartLine products<br />
in this valve range in particular<br />
combine excellent performance<br />
with the corresponding costefficiency.<br />
They are therefore<br />
preferably used in chemical supply<br />
systems as well as wet process<br />
equipment.<br />
The aforementioned range is<br />
rounded off by sensor solutions for<br />
flow and pressure measurement,<br />
accessories such as tubes and<br />
fittings, electrical position<br />
indicators and controllers as well<br />
as stainless steel valves and further<br />
metal valves with plastic linings.<br />

THE PLUG VALVE COMPANY<br />
ARMATUREN<br />
free of cavities & maintenance<br />
Plug Valve For<br />
Double Block + Bleed + Inspection-Service<br />
Type DBI<br />
The AZ-Armaturen double block and bleed<br />
valve is a plug valve with two independent<br />
sealing areas which provide a tight seal<br />
against pressure from both ends of the<br />
valve. Additionally, the cavity between the<br />
sealing areas can be vented/bleeded (DBI<br />
Type A) in order to recognize a leakage on<br />
one sealing immediately.<br />
The AZ-Armaturen double block and bleed<br />
valves are used in critical applications<br />
where any kind of leakage is not allowed<br />
to occur. Furthermore, the valve can be<br />
fitted upstream and/or downstream with<br />
additional inspection valves (Type B & C).<br />
This provides the advantage of inspection<br />
capabilities of the medium and draining<br />
possibilities for revision-service. The<br />
AZ-Armaturen double block and bleed<br />
valve can be operated manually or fully<br />
actuated.<br />
The AZ sales team is looking forward to<br />
assisting you with all your technical questions.<br />
