Manual Reset High Pressure Switch

The controller adopts a piston type sensor, which is divided into three types: with a drain port, a non-leak piston and a combination of a piston type and a diaphragm type.

It can be used for compressed air containing oil mist and other gas containing oil mist that has no corrosive effect on the pressure sensor material, 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.

How does a pressure switch work?

The force switch is a simple pressure control device. When the measured pressure reaches the rated value, the pressure switch can send out an alarm or control signal.  

The working principle of the pressure switch is: when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, and the switch element is pushed directly or after comparison to change the on-off state of the switch element to achieve 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.    

Switching elements include magnetic switches, mercury switches, micro switches, etc.    

There are two types of pressure switches: normally open and normally closed.

How do you test a pressure switch?

Calibration method of pressure switch:

  1. Find out the action setting value of the tested instrument according to the specification.
  2. Select an appropriate pressure signal source to pressurize the test meter. A standard pressure gauge with an appropriate range detects the signal pressure. Use a multimeter to measure the on and off states of the contacts.
  3. For the high report switch, slowly increase the pressure from low to high, and observe the multimeter. When the multimeter indicates a sudden change, the evaluation of the standard pressure gauge is the high reported value.
    Then slowly lower the pressure. When the multimeter indicates a sudden change again, the evaluation of the standard pressure gauge is the reset value.
  4. For the under-report switch, the test pressure should be increased above the set value first, and then slowly decreased.
    When the multimeter indicates a sudden change, the evaluation of the standard pressure gauge is a low value.
    Press again slowly, and when the multimeter indicates a sudden change again, the indication value of the standard pressure gauge is the reset value.
