Principle Introduction:
MIX2002 Combustible(LPG/C3H8) Gas Sensor advanced planar construction is comprised of heater and metal oxide semiconductor material of subminiature Al2O3 ceramic plate, fetch out electrode down-lead, encapsulation in metal base and cap. When there is methane/smoke/lpg. The LPG/C3H8 sensor’s conductivity will become higher along with the gas concentration rising. With simple electro circuit, convert change of conductivity to correspond output signal of gas concentration.
Feature:
* Good linearity
* Fast response and recovery
* Good stability and sensitivity
* Strong anti-interference ability
* Low power consumption
Application:
* Industrial usage combustible gas leakage detectors
* Domestic usage gas leakage alarm
