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.
Features
High sensitivity to CH4 gas
Excellent anti-interference ability
Excellent stability
