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 electrocircuit, convert change of conductivity to correspond output signal of gas concentration.
Applications :
Domestic smoke leakage alarm, industrial smoke gas alarm and portable smoke detector.
Technical parameters :
Tips:For more parameter information, please refer to the latest manual provided by salesman.
