MP-2 model with 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 the target gas exists , the sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electro circuit, convert change of conductivity to correspond output signal of gas concentration.
Applications
Domestic smoke leakage alarm, industrial smoke gas alarm and portable smoke detector.
Features
Good sensitivity to LPG, smoke in wide range
Small size
Long lifespan
Low cost
Simple circuit
