HPT300-C2 Refrigeration Pressure Sensor

Refrigeration pressure sensor adopts the latest generation of ceramic pressure core, which can be used in a low temperature environment of -20-125°C. The shell adopts a "passivation" process, which is not affected by moisture and condensation. It is widely used in refrigeration and HVAC systems and is compatible with various types of refrigerant measurement.

Application :

● Refrigeration equipment

● Centrifugal compressor

● Screw-type,reciprocating and turbo compressors

● Air-conditioner production line testing

● HVAC Systems

● Energy and Water Treatment
