Accurate MC112C Catalytic Flammable Gas Sensor with Standard Encapsulation and Metallurgy Powder Mesh
MC112/MC112C/MC112D Catalytic Flammable Gas Sensor
Profile :
MC112/ MC112C/ MC112D 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.
Features:
It has good sensitivity to methane in wide range, and has advantages such as long lifespan, low cost and simple drive circuit &etc. The bridge output is linear, quick response, good repeatability and selectivity, good stability, excellent resistance to the interference of H2S gas and organosilicone.
Main Applications:
It is widely used in industrial occasion to detect the concentration of natural gas,LPG, coal gas and alkanes. It is also used in combustible gas leakage alarm system, combustible gas detector and gas concentration meter and so on.
