Catalytic Gas Sensor for LPG, Combustible Gas, Gasoline, Alcohol - MC119

Mouse over image to zoom

MC119 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
