benzene combustible gas sensor
catalytic combustion principle, Wheatstone bridge structure for combustible gas sensor
benzene combustible gas sensor
MC113 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
*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.
