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 204 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.
