DJC-KR Combustible Gas Detection Alarm Device


Combustible gas alarm system uses the combustible gas density detector installed on site to detect the density of combustible gas in the pump compartment and living areas. The detector will changeover the density of the combustible gas into 4-20 mA signals and send to the Data Collector Module which, in turn, changes the signals into digital signals and send to the LCD (liquid crystal display) unit by the CAN bus. The Liquid Crystal Display unit can be installed in the bridge, centralized control room and many other places to simultaneously display the combustible gas density. Once the density of the combustible gas has reaches the pre-alarm value and the alarm value (which can be modified), the system will generate audible and visible alarm signal.
