The RAEGuard IR is a permanently mounted (fixed) hydrocarbon gas sensor/transmitter that operates from a 9 to 36 VDC power source and provides an analog (4 to 20mA) and digital (RS-485) signal output in the range of 0 to 100% LEL hydrocarbon equivalent. The RAEGuard IR is based on RAE Systems’ patented technology of non-dispersive infrared (NDIR) for methane or hydrocarbon. Housed in an explosion-proof enclosure, the RAEGuard IR is equipped with a local digital display of the gas concentration and function keys for performing calibration. The RAEGuard IR is operated with a standard 4 to 20mA/RS-485 controller or as a stand-alone sensor module.
