The RAEGuard LEL is a permanently mounted (fixed) catalytic bead combustible gas detector/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 combustible gas. Housed in an explosion-proof enclosure, the RAEGuard LEL is equipped with a local digital display of the gas concentration and function keys for performing calibration. The RAEGuard LEL can be operated with a standard 4 to 20mA/RS-485 controller or as a stand-alone sensor module.
