MPn-4C Methane Gas Sensors High Sensitivity Semiconductor
MPn-4C Methane Gas Sensors High Sensitivity Semiconductor
Description
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.
