Product Details
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.
