High pressure switch is a multifunctional high pressure switch suitable for a variety of hydraulic and pneumatic applications. The setting value is adjustable, and its adjustment range is 0.3-40MPa.

High pressure switch can be used for compressed air containing oil mist and other gas containing oil mist that has no corrosive effect on pressure sensor materials, hydraulic oil, water-oil emulsion and neutral liquid medium with good lubricating performance. The setting value of the controller is adjustable, and its adjustment range is 0.3-40MPa.
Sino-Inst offers a variety of Pressure Switches for pressure control. If you have any questions, please contact our sales engineers.

How does a high pressure switch work?
Working principle:
When the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor moves instantly. Push the switch connector on or off by connecting the guide rod.
When the pressure drops or rises to the rated recovery value, the disc is reset instantly. The switch resets automatically. Or simply speaking, when the measured pressure exceeds the rated value, the free end of the elastic element produces displacement, pushes the switch element directly or after comparison, changes the on-off state of the switch element, and achieves the purpose of controlling the measured pressure.
The elastic elements used in the pressure switch include a single-turn spring tube, diaphragm, bellows and bellows.
