Flammable gas detector is a kind of fixed installed high-end flammable gas detector used for detecting the leakage of industrial inflammable gas, with design patent and complete output, suitable for a variety of places.

There are four indication lamps on the MR-61Ex-B panel, respectively showing operation status, alarm status, fault status and calibration status.

The detector possesses the function of the sensor poison protection circuit and sensor drop-off fault alarm.

Three output mode: 4～20mA standard current output, RS-485 output, alarm upper and lower limit, fault three-group relay contact output, the alarm is open contact at normal status, constant close signal at fault status.

With two built-in decimal dial switch, the detector is convenient for setting its address, RS-485 output mode connected with bus-system MR-3000 flammable gas alarm controller, 4～20mA output mode connected with MR3000-A multiline MR3000-A flammable alarm controller. The detector can be used alone with power supply, also can be connected with DCS, PLC and other industrial automation system as per output mode.automation system as per output mode.
