Flat Semiconductor Refrigerant Sensor MP510C
Summary:
The MP510C Freon gas sensor uses a multilayer thick film manufacturing process to fabricate heating and measuring electrodes and a metal oxide semiconductor gas-sensitive layer on a miniature Al2O3 ceramic substrate, and encapsulate it in a metal casing. When the detected gas exists in the ambient air, the conductivity of the sensor changes. The higher the concentration of the gas, the higher the conductivity of the sensor. This change in conductivity is converted into an output signal corresponding to the gas concentration through the circuit. The product has good anti-interference ability against common gases such as alcohol and acetic acid in usage scenarios.
Feature:
* High selectivity,
* Good anti-interference,
* Long lifespan,
* Good stability
* Can detect kinds of refrigerant gases R32, R134a,R410a,R290.
