This version of Xgard is a Flameproof gas detector, designed to detect flammable gas present in ambient air, at concentrations not exceeding the Lower Explosive Limit (LEL) of the target gas for which it is calibrated. Xgard Type 5 is powered by 24 V dc (nominally) and provides a 4-20 mA signal (sink or source) proportional to the gas concentration. The detector is certified II 2 GD Ex db IIC T6 Gb, and is suitable for use in Zone 1 and Zone 2 hazardous areas. Electrical connections to the detector are made via the terminal block on the PCB shown below.
