MC112 Catalytic Flammable Gas Sensor

For industrial use to detect CH4, C3H8 &etc.

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.

Product Advantages:

*Bridge output voltage in linear
*Fast response & Long lifespan
*Good repeatability and selectivity
*Stable and reliable
*Resist H2S poisoning & organosilicone.

Product Description:

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.
