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 **0PSI (5.5MPa) in various
systems.
