The combustible gas alarm device detects the concentration of combustible gases in the pump compartment or living area through a combustible gas concentration sensor installed on site. The sensor converts the concentration of combustible gas into a 4-20mA signal and transmits it to the data acquisition module. The data acquisition module then converts the 4-20mA signal into a digital signal and transmits it to the LCD display unit through the CAN bus. The LCD display unit can be installed in multiple locations such as the driver's cab and the control room to synchronously display the concentration of combustible gas in real time. Once the concentration of combustible gas reaches the pre alarm value and alarm value (adjustable), the sound and light alarm will start.
