IR2100 - Infrared Point Gas Detector
The Model IR2100 detection principle is based on measuring the absorption of infrared radiation passing through a volume of gas using a dual beam, single detector method. The IR detector measures the intensity of two specific wavelengths, one at an absorption wavelength and another outside of the absorption wavelength. The gas concentration is determined by a comparison of these two values. All of the Model IR2100's electronics are contained within an explosion-proof housing so that the detector information can be processed at the detector site.
The Model IR2100 provides a 4-20 mA signal which is proportional to 0 to 100% LEL gas concentration at the detector. Another feature of the Model IR2100 is an RS-485 signal buss running MODBUS-RTU to link up to 32 Model IR2100's. The RS-485 output provides status, alarm, fault and other information for operation, trouble shooting or programming the unit.
