Pressure Switch

1,OPerational principle:

this series of pressure switches is mainly manufactured using the built-in stainless steel flip action diaphragm, which can flip in the opposite direction after sensing a certain pressure. When the diaphragm acts, it will open the electrical contacts through a guide rod. When the sensing pressure drops below the recovery value, the pressure switch can automatically reset.

 

2,Purpose:

When the system pressure is above or below the set pressure, disconnect the circuit to protect the equipment. Pressure switches are widely used in industries such as air conditioning, heat pumps, and water pumps.

 

this series of products is specifically designed and manufactured for refrigeration equipment that uses carbon dioxide as a refrigerant, and its refrigeration system pressure is significantly higher than the special requirement of conventional refrigerant pressure. It is used for high-pressure protection of the system; It is also suitable for equipment and tools with high-pressure protection pressure greater than 800PSI (5.5MPa) in various systems.
