1 PC MC109 Catalytic Flammable Gas Sensor

MC109 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.  Application It is widely used in industrial occasion to detect the concentration of hydrogen, ethyne, gasoline, VOC such as alcohol, ketone, benzene.   Features The bridge output is linear, quick response, good repeatability and selectivity, good stability, excellent resistance to the interference of H2S gas and organosilicone.  Specifications Model MC109 Sensor Type Catalytic Standard encapsulation Plastic encapsulation Working voltage(V) 2.5±0.1 Working current (mA) 100±10 Sensitivity (mV) 1% H2 20～50 1% C2H2 40～90 Linearity ≤5% Measuring range (%LEL) 0～100 Response time (90%) ≤10s Recovery time (90%) ≤30s Working environment -40～+70℃，less than 95%RH Storage environment -25～+70℃，less than 95%RH Life span  2 years   * The description and specifications might be changed without notice.
