MC21B Model Standard Encapsulation Catalytic Flammable Gas Sensor for Accurate Detection
MC21B Catalytic Flammable Gas Sensor
Product description:
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.
Characteristics:
Bridge output voltage in linear; Fast response; Good repeatability and selectivity; Stable and reliable; Resist H2S poisoning & organosilicone.
Main Applications:
It is used for household occasions to detect combustible gases leakage alarm or concentration such as natural gas, liquefied gas and so on.
