WSP4889 refrigerant Gas Sensor

Principle Introduction:
WSP4889 Refrigerant detection gas sensor adopts multilayer thick film manufacturing technology. The heater and metal oxide semiconductor material on the ceramic substrate of subminiature Al2O3 are fetched out by electrode down-lead, encapsulated in metal socket and cap. Conductivity of the sensor is affected by the concentration of target gas. The higher the concentration is, the higher conductivity of sensor gets. Users can adopt simple circuit to convert variation of conductivity into output signal corresponding to gas concentration. 

Applications :
It is widely used in domestic, environmental occasions for Refrigerant detection.
