Catalytic Combustion Gas Sensor

The catalytic combustion gas sensor is based on the Wheatstone bridge principle. The detection element is coated with a catalyst, and the flameless combustion of combustible gases on its surface causes a change in the temperature of the platinum wire, leading to a variation in resistance and the output of an electrical signal. It is used for detecting combustible gas leaks and finds applications in explosion-proof environments such as petrochemical plants and coal mines.
Selection
When selecting, consider matching the types of gases to be detected with the lower explosion limit, and pay attention to the sensor's resistance to poisoning and long-term stability. The working environment should avoid inhibitors such as silicates and lead compounds. Choose the appropriate certified model based on the on-site explosion-proof rating, and perform regular calibration to maintain detection accuracy.
