SCH-001 Methane Gas Sensor is working with Catalysis Combustion Principle. The arms of Electric-Bridge is consists of the testing element and the compensating element. When contacting with the combustible gas, the resistance of the compensation element would rise, and the bridge would output the voltage variable. The voltage variable will rise at a rate proportionate to the gas consistency. The compensating element is used of compensating temperature.
Its main features are: Linear the voltage output of circuit, short responding time, good reproducibility and selectivity, good stability and reliability and resist H2S poison.
