MC112 sensor for combustible gases

MC112 original manufacturer Listed company in Shenzhen Anti-explosion structure For industrial and mine fields

MC112  Catalytic Gas Sensor

MC112 operate on the catalytic combustion principle, and its two arms of electric bridge consists of a test element and a compensate element. The resistance of the test element rised when meeting the combustible gas, in the same time, the output voltage of the bridge changed, the voltage variable is rised in direct proportion as the gas concentration, the compensate element as a reference, and compensate of temperaturer and humidity.

Feature                                                                        

Configuration                                              

*The bridge output in liner                                              

*Fast response                                      

*Good reproducibility and selectivity                                           

*Working steability

*Excellent resistance of H2Ssilicon poisoning

Application                        

Application in gas concentration detection in industrial field such as natural gas, LPG, coal gas, alkane ect combustible gas, and gasoline, Alcohol, ketone, benzene ect organic solvent;

Combustible gas leaking alarm or detectors;

Gas concentration meter.
