Flammable and Explosive Gas Alarm

Flammable and explosive gas alarms detect the concentration of specific gases in the air through sensors and trigger audible and visual alarms when the concentration reaches a preset threshold. They are used in places such as petrochemical facilities and laboratories where combustible gases may be present, enabling early warning of leaks.
Selection
Select the corresponding sensor based on the type of gas to be detected, ensuring that the explosion-proof rating matches the on-site environment. Verify that the detection range covers the lower explosion limit of the target gas, and regularly calibrate and maintain the sensor. The wiring method must be adapted to the installation area conditions.
