instantaneous readings; and peak or valley hold
processing. Up to 32 sensors can be installed on a
single multidrop network. All the IR sensors are fitted
with precision germanium lenses for accurate optics.
These compact sensors are small enough to fit almost
anywhere and their rugged stainless steel housings
make them ideal for applications where cleanliness
and hygiene are paramount.
The optional DP240 is a 320 x 240 pixel touch screen
terminal with a 89 mm (3.5") color TFT display. It
allows the user to display data from up to eight
infrared sensors and configure each sensor
individually. The configuration parameters include
emissivity setting, signal averaging, peak or valley
hold processing and reflected energy compensation.
There are two versions available. Each one provides
all of the features above, however, the enhanced
DP240-AR also provides analogue transmission for
up to 4 sensors, plus two adjustable alarm outputs
per sensor for all 8 sensors.

The OS211 Series is a range of high quality, low cost,
compact sensors which measure the temperature of
inaccessible or moving objects and materials. They
measure temperatures from -20 to 500°C (-4 to 935ºF),
accurately and consistently, with an outstanding
response time of 240 ms. Two-way digital
communications via a built-in RS485 MODBUS RTU
interface enables the user to adjust the emissivity
setting; compensate for reflected energy; apply
filtering; select maximum and minimum, average or
