CH4 sensor MC227D

LPGcombustible gaspropane

MC227D adopts 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 rises once it meets the combustible gases, in the same time, the output voltage of the bridge changes and the voltage variation rises in direct proportion to the gas concentration. The compensate element, as a conference, has the function of compensating temperature and humidity. Application It is widely used in public places (not industrial occasion) to detect the concentration or leakage of combustible gases such as natural gas, LPG, coal gas. Features Bridge output voltage in linear Fast response Good repeatability and selectivity Good stability and reliability Resist H2S poisoning & organosilicone.
