MP-4 MP-4C Flammable Gas Sensor Lower Consumption Small Size Fast Response And Resume For Industrial Flammable Gas Alarm And Portable Gas Detector
MP-4 Flammable Gas Sensor Lower Consumption Small Size Fast Response And Resume For Industrial Flammable Gas Alarm And Portable Gas Detector
MP-4 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.
Features:
* Lower consumption
* Small size
* Fast response and resume
* Highest sensitivity
* Excellent stability and long life
* Easy circuit and big signal output
* Excellent selectivity
Application:
It is widely used in domestic gas leakage alarm, industrial flammable gas alarm and portable gas detector.
