Catalytic Combustion Type Gas Detector

Catalytic combustion gas detectors utilize the heat generated by the low-temperature oxidation of combustible gases under the action of a catalyst. The temperature change is measured using a Wheatstone bridge and converted into gas concentration. These detectors are used to detect combustible gas leaks and are commonly employed in explosion-proof environments such as petrochemical plants and coal mines.
Selection
When selecting, ensure that the type of gas to be measured matches the instrument's range, pay attention to the impact of ambient temperature and humidity, check whether the explosion-proof rating meets on-site requirements, regularly calibrate the sensor lifespan, and consider the influence of cross-interfering gases.
