Fixed Monitors

RAE Systems fixed gas detection monitors

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) 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 controller or as a stand-alone sensor module.

The RAEGuard EC is a permanently mounted (fixed) toxic gas or oxygen sensor/transmitter that operates from a 9 to 36 VDC power source and provides an analog (4 to 20mA) signal output. Housed in an explosion-proof enclosure, the RAEGuard EC is equipped with a local digital display of the gas concentration and function keys for performing calibration. The RAEGuard EC is operated with a standard 4 to 20mA/RS-485 controller or as a stand-alone sensor module.

The RAEGuard PID is a permanently mounted (fixed) Photoionization Detector (PID) transmitter that operates from a 9 to 36 VDC power source and provides an analog (4-20 mA) signal output in three fullscale ranges of 20 ppm, 100 ppm, or 1,000 ppm isobutylene equivalent. Housed in an explosion-proof enclosure, the RAEGuard PID is equipped with a local digital display of the gas concentration and functional keys for performing calibration.

The FMC-60 is a multi-channel controller that has been designed to operate in the full range of environments from commercial premises through to heavy industrial applications which may require hazardous area sensing.

The FMC-60 system operates on a 4 core (addressable) or 2/3 core (direct) cable network and has the capacity to monitor up to 64 addressable and 16 direct sensors of various gas types.

Each gas sensor continuously monitors the atmosphere, reporting any hazardous conditions to the control unit, for display by the alpha numeric screen indicating the reporting sensor, gas type, concentration and alarm status. Alarm levels that are exceeded will automatically activate a variety of signal outputs including analogue/digital data and user selectable relays.
