6.2.2 Point IR Gas Detector
General Monitors has developed an alternative field device for combustible gas
applications. The Model IR2100 Infrared Point Detector is a microprocessor based
hydrocarbon gas detector (figure 65). The General Monitors Model IR2100 is calibrated
at the factory and needs no routine field calibration.
The Model IR2100 Infrared Point Detector continuously monitors combustible gases
below the Lower Explosion Level (LEL) range* and provides a 4 to 20mA analogue
signal proportional to the 0-100% LEL concentration it detects along with a digital RS485
output, allowing unit to be addressable via Modbus Protocol.
Sensor data and status information for the Model IR2100 can be transmitted to a variety
of General Monitors’ readout units.
The Model IR2100 Infrared Point Detector operates from a n 24VDC CE
marked supply which must be supplied by the customer.
