Mine Methane Sensor
Catalytic combustion principle with anti-explosion function
100% LEL detecting range with linear output

Mine Methane sensor 

 

MC115 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 H2S,silicon 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.
