It is used for flammable gas detection, which adopts advanced flat production technology. The heater and metal oxide semiconductor material on the ceramic substrate of subminiature Al₂O₃ are fetched out by electrode down-lead, encapsulated in metal socket and cap. When the target gas exists, the higher the concentration of target gas in the air, the higher conductivity of the sensor is. Use simple circuit to convert the variation of conductivity to output signal corresponds to gas concentration.
