This 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 932ºF), accurately and consistently, with an
outstanding response time of 240 ms. Infrared (IR)
sensors are available as either 2- or 4-wire units.
Two-wire IR sensors transmit the target temperature
as a 4 to 20 mA output and offer a simple solution
for most non-contact temperature measurement
applications. Four-wire IR sensors transmit the target
temperature as a 0 to 50 mV or thermocouple output
(Type J, K or T) plus the internal sensor temperature
as a 4 to 20 mA output. This second output can be
used to ensure that the sensor is being operated within
the correct ambient temperature limits and prevent
damage caused by overheating or overcooling. It can
also be used to give an approximate indication of
the air temperature surrounding the sensor. IR sensors
are fitted with precision germanium lenses
for accurate optics.

The L-shaped fixed mounting bracket offers a rigid support
for the sensor and allows fine adjustment in a single plane.

Adjustable Mounting Bracket
The adjustable mounting bracket consists of a fixed mounting
bracket plus another L-shaped bracket. When assembled as
shown the adjustable mounting bracket offers a rigid support for
the sensor and allows fine adjustment in two planes.
Option “WC” air/water cooled
jacket, additional cost.
Air Water Cooled Housing
The air/water cooled housing allows the sensor to withstand
ambient temperatures which exceed the normal 70°C limit. Air or
water (depending on the degree of cooling required) flows into
Air Purge Collar
The air purge collar is used to keep dust, fumes, moisture and
other contaminants away from the lens. Air flows into the fitting
on the side and out of the aperture at the front.
Laser Sighting Tool
The laser sighting tool screws onto the front of the sensor during
installation and indicates precisely where the sensor is aiming.
Once the sensor has been aimed at the centre of the target and
locked in position the laser sighting tool can be removed. The
laser is activated by means of a push button on the front of the
tool which has a latching mechanism.

condensation forming on the lens, the air/water cooled housing is
supplied complete with an air purge collar. Please note, the air/
water cooled housing must be ordered with the sensor and cannot
be fitted by the user.
