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.
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
