LPG gas sensor MC21B

combustible gaspropanemethane

MC21B 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 used for household occasions to detect combustible gases leakage alarm or concentration such as natural gas, liquefied gas and so on. Features Bridge output voltage in linear; Fast response; Good repeatability and selectivity; Stable and reliable; Resist H2S poisoning & organosilicone.
