1 PC MP511D Refrigerant Gas Sensor

The MP511D 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 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. Application Used for leak detection of refrigerants in air conditioning and refrigeration systems Features High selectivity, fast response, good anti-interference, long lifespan, good stability Can detect kinds of refrigerant gases R134a, R454b, R290.
