Description
IR Sensor
The IR sensor is a smart sensor that stores sensor parameters including the
target gas, detection range, alarm points, and calibration settings in its
memory. So a sensor can be calibrated at the factory and shipped as a
replacement sensor without the need to calibrate the sensor when it is
installed as long as it is installed during the sensor’s valid calibration period
which is typically 6 months. In addition, you can change an existing IR
channel from one type of IR sensor to another and the GX-6000 will
automatically load all the sensor parameters and configure the IR channel for
the new sensor. See “Replacing an IR Sensor” on page 200 for instructions to
replace or change an IR sensor.
The IR sensor is a cylindrical sensor with a diffusion opening on the front and
a connector on the back. The IR sensor is installed in one of the two smart
sensor sockets and is held in place by the sensor gasket and the flow chamber.
