The pressure switch is mainly used in the refrigeration system, in the pipeline circulation system of high pressure and low pressure, to protect the abnormal high pressure of the system to prevent damage to the compressor.
After being filled, the refrigerant flows into the aluminum shell (that is, inside the switch) through the small hole under the aluminum shell. The inner cavity uses a rectangular ring and a diaphragm to separate the refrigerant from the electrical part ...
1: Wide pressure control range:You can choose any on and off value (including negative pressure value) for the switch, and we will customize it for you.
2: Applicable medium: liquid, gas, refrigerant
3: Interface method: The interface of this pressure switch is a threaded interface,Commonly used thread specifications are G1/8, NPT1/8, G1/4, NPT1/4, M10*1, etc.The thread can be customized according to your requirements.In addition to this, there can also be small copper pipe interfaces, large...
