1 PC MPn-4C CH4 Methane Flammable Gas Sensor

MPn-4C adopts a multi-layer thick film manufacturing process, which integrates a heating electrode, a measuring electrode and a metal oxide semiconductor gas sensitive layer on an Al2O3 ceramic substrate, and encapsulates it in a metal housing. When the detected gas is present in the ambient air, the conductivity of the sensor will change, and the higher the concentration of the gas, the higher the conductivity of the sensor. This change in conductivity can be converted into an output signal corresponding to the gas concentration using a simple circuit. The product has good anti-interference ability to common gases such as alcohol and acetic acid in the use scene. Application It is widely used in combustible gas leak monitoring devices, fire/safety detection systems for home, factory and commercial use; Flammable gas leak alarm, gas leak detector, etc. Features High sensitivity to CH4 gas Excellent anti-interference ability Excellent stability Specifications Model MPn-4C Sensor Type Flat surfaced Standard Encapsulation Metal cap Target Gas CH4, Nature gas,marsh gas Detection range 300~10000ppm (methane, natural gas)  Standard Circuit Conditions Loop Voltage Vc ≤24V DC Heater Voltage VH 5V±0.1V AC or DC Load Resistance RL Adjustable Heater consumption PH ≤350mW Sensitive resistance RS 1KΩ～20KΩ(in5000ppm CH4) Sensitivity S Rs(in air)/Rs(5000ppm CH4)≥8 Concentration Slope α ≤0.6(R5000ppm/R1000ppm CH4) Standard test conditions Temp.  Humidity 20℃±2℃；55%±5%RH Standard test circuit Vc:5V±0.1V; VH: 5V±0.1V Preheat time Not less than 48 hours O2content 21% (not less than 18%) O2 concentration effects initial value, sensitivity and repeatability.
