The DPS33 differential pressure switch features highly sensitive pressure sensors on both sides that trigger the switching mechanism to control equipment such as motor-driven valves. It is typically used to manage pressure differences between supply and return pipes in water and oil systems. As a pump differential pressure switch, it can control a bypass valve near the pump, opening or closing the valve when the differential pressure reaches the set value to help maintain stable system operation.
Adjustable design for differential pressure setting.
Manual reset and automatic reset modes are optional.
Using bellows for pressure transfer, it has the characteristics of stable linear pressure coefficient and long life.
Various mounting modes of mounting brackets can be customized.
