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

Control valve now available in ANSI Class 600 and PN 63
The ARCA ECOTROL® 8C control
valve has proven itself in the
process chemical, oil & gas as well
and power generation industries
for many years.
The unique cage retainer /
clamping seat system enables
simple maintenance to be done
without the need for special tools.
The ECOTROL offers a wide
range of process tailored valve
internals, including standard
parabolic plugs (either metal
seated or with the patented Arca
soft seal system), multistage lownoise
perforated as well as double
guided valve plugs.
The gland packing system
is certified according to TA Luft
respectively ISO15848 Class B for a
temperature range from -46 up to
+200°C.
ARCA of Germany have now
extended the range to include
valves with ANSI 600 and PN63
flanges or butt-welded ends.
The valves meets ASTM and
ASME standards applicable to the
chemical and oil & gas industries.
With the associated ARCA actuator
type 812 with its innovative multispring
field reversible diaphragm
and associated intelligent
positioners and optional
spring chamber blanketing
with instrument air, the ARCA
ECOTROL® 8C is a technically, ecofriendly
and economical process
control valve solution.

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