Product introduction
-
I.Freon sensorWSP5110 product description
-
The WSP5110 Freon gas sensing element uses advanced planar production technology, forming a heater and metal oxide semiconductor gas-sensitive material on a miniature Al2O3 ceramic substrate, with electrode leads extending out, encapsulated in a metal base and cap. When the target gas is present, the higher the concentration of the gas in the air, the higher the conductivity of the sensor. A simple circuit can convert this change in conductivity into an output signal corresponding to the gas concentration.
