Gas Detection

IR400 Point IR Gas Detector

The Model IR400 Infrared (IR) Point Detector is a microprocessor-based hydrocarbon gas detector that continuously monitors combustible gases and vapors within the lower explosive limit (LEL) and provides alarm indication. All electronics are contained within an explosion-proof housing so that the IR400′s detector information can be processed locally. The IR400 operates with a 4-20mA signal, which is proportional to 0 to 100% LEL gas concentration at the detector. Configurations with analog output, Modbus and HART are also available. Modbus and HART data can be used for predictive maintenance.

IR5500 Open Path Infrared Gas Detector

The Model IR5500 is an open path IR gas detector that provides continuous monitoring of methane and propane gas concentrations. The system consists of an IR source and receiver which continuously monitors for methane in both the 0 to 5000 ppm•meter and 0 to 5 LEL•meter range. A 0 to 2000 ppm•meter and 0 to 1 LEL•meter range is also available for monitoring propane. The IR5500 provides two 4-20 mA analogue signals proportional to each of the above ranges, in addition to a digital display and relay contacts.
