Differential Pressure Switch

The DPS52 is an adjustable differential pressure switch capable of detecting miniscule changes in pressure due to the size and proven design. The switch set point or switching point can be field adjustable without the need of a manometer by simply using the adjustment knob and the built in calibrated visual scale. This switch is equipped a clear cover that not only protects the adjustment knob to be move involuntary but also provides class IP54 protection. Certifications: UL  

The DPS33 differential pressure switch is a protective device for refrigeration compressors or pressure lubrication of other mechanical. In the refrigeration system, the switch receives the two pressure signals of the discharge pressure of the lubricating oil pump and the suction pressure of the compressor, and maintains a certain range of difference between these two pressures, and when the difference is smaller than the set value, the switch will actuate immediately to automatically cut off the compressor circuit and stop the compressor,thus protecting the compressor.
