MPn-4C CH4 Methane Flammable Gas Sensor For Manufacturing Process
Target Gas: CH4, methane, natural gas, marsh gas
- Detection Range: 300 - 10000 ppm (methane, natural gas)
- Detection Principle: Semiconductor
- Characteristics: High sensitivity to CH4 gas, excellent anti - interference ability, excellent stability
- Manufacturing Process: 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.
- Working Principle: 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.
- Application: 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.
