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 available. Modbus and HART data can be used for predictive maintenance. Approvals: CSA, FM, ATEX, IECEx, CE Marking. SIL 3 suitable, certified by FM to IEC 61508.
