New inline analyser system for edible oil and fat processing
19.2
Introducing the OPTIQUAD-EOF
4050 W for the continuous inline
measurement of free fatty acids
(FFA), total polar material (TPM),
peroxide value (POV), moisture
or dirt. The optical spectroscopic
analyser system is aimed at frying
and other edible oil as well as fat
applications.
OPTIQUAD-EOF 4050 W
measures directly in the pipe:
analysis is achieved via an optical
window mounted in a standard
VARINLINE measuring section.
The readings of FFA, TPM, POV
moisture or dirt are provided
instantly for process control or
dynamic control loops via four
4...20 mA outputs. Depending on
the application, measurement of
anisidine value (AV) and iodine
value (IV) are possible. Compared
to conventional laboratory
methods used to obtain these
values, OPTIQUAD-EOF 4050 W
reduces the need for sampling,
sample transport and handling,
and the associated sources of error
and costs.
The optical spectroscopy
analyzing method allows for a
wide range of use in edible oil
applications, such as oil extraction,
oil refinement and frying processes
up to oil recycling, as well as fat
processing. For example, the
continuous inline measurement
of FFA content in frying oil helps to
minimize the addition of fresh oil:
the FFA value can be kept below
a defined limit whilst allowing to
maintain a high level of quality. It
also provides a wide measuring
range, e.g. 0…98% for FFA, and
an accuracy of RMSEp: ±0,03%
up to ± 1% FFA, depending on the
measurement range.
OPTIQUAD-EOF 4050 W
spectroscopic analysis system
consists of the analyser unit
(protection rating IP65/NEMA4X)
and the operating unit, an
industrial PC with touch screen
display for parameterisation and
automatic calibration in a stainless
steel housing (IP65/NEMA4X),
optionally built into a switch
cabinet. It uses up to four measuring
methods (transmission, scattering,
fluorescence and refraction)
with up to 12 wavelengths
from ultraviolet to infrared.
The underlying calibration is
calculated automatically from
reference data specific to the
application. OPTIQUAD-EOF 4050
W is the successor of OPTIQUAD-
FFA 4050 W.

New relative humidity probe that hands control to the user
Michell Instruments has
introduced the new
HygroSmart HS3 advanced
interchangeable relative
humidity and temperature probe.
It’s 100% configurable, giving
users maximum flexibility. It
also allows for alterations to RH
measurements, to keep step with
changes or developments in the
process.
Users can set the zero/span
range, output signals and choose
from five output parameters
(including dew point). All these
changes and settings are made on
a PC via the application software.
The unit can also be ordered
directly from Michell with the
probes fully configured to unique,
individual specifications.
The new probe ensures zero
process downtime by keeping
maintenance to a minimum
with an interchangeable sensor.
When recalibration is due, the
old HygroSmart HS3 sensor is
simply exchanged for a new,
freshly calibrated one. This simple
procedure allows for the probe to
remain installed, and takes only a
few seconds to carry out. Using the
replaceable sensor ensures that
the HygroSmart HS3 probe has a
low life-time cost, when compared
to fully disposable probes.
Alternatively, minor calibration
adjustments can be easily made
on any installed HS3 probe, with a
5-point digital trim adjustment via
the application software to ensure
maximum accuracy without
needing to replace the sensor.
Designed for demanding
industrial conditions, the
HygroSmart HS3 probe features
a solid corrosion-resistant body,
10 bar pressure sealing and IP67
pressure rating. In addition it also
has an accuracy of 0.8%RH, making
it among the most accurate and
reliable RH probes on the market.

Safe AS-I input module especially for light guard applications
The new safe AS-i input
module is designed for the
connection of electro-sensitive
protective equipment (ESPE) with
electronic outputs to EN 61496-
1. It is particularly suited for the
connection of safe inductive
sensors such as GM705S. Pulse
pick-ups for the display of muting
functions can be connected via
M12 sockets.
The integrated outputs
ensure the connection of two
signal lamps. The tried-andtested
quick mounting avoids
wiring faults. The AS-i flat cable
can be connected from three
different directions. There is one
M12 connecting socket each for
the transmitter, the receiver and
the two signal outputs.
Fail-safe sensors with a
current consumption below 200
mA can be operated on AC507S
without auxiliary voltage. The
LEDs indicate the status of the
inputs and outputs and the
communication.
The new safe AS-i input
module meets the requirements
up to SIL3 according to EN 62061
and PL e to EN 13849-1. In the
event of a fault, the integrated
communication monitoring
switches the signal outputs off.
