RAE Systems RAEGuard IR

Fixed Hydrocarbon Gas Monitor, 4-20 mA transmitter

The RAEGuard IR is a permanently mounted (fixed) hydrocarbon gas transmitter that operates from 9 to 36 VDC power source and provides a 4-20mA analog output in the range of 0-100%LEL hydrocarbon equivalent or ppm concentration of CO2.

The RAEGuard IR is based on RAE's patented technology of non-dispersive infrared (NDIR) for methane, hydrocarbon, or carbon dioxide measurement.

The microprocessor based circuit is 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 4-20mA controller or as a stand-alone sensor module.
