Tips: Working Principle of Pressure Switch.

The pressure switch is mainly used to detect the pressure of the relevant detection part. Its working principle is to sense the pressure of the external environment through the built-in sensor. When the external pressure value exceeds or falls below the safety critical point, the diaphragm of the sensor will vibrate and change and then send out a control signal, and the signal will guide the switch to change, so when the pressure of the environment returns to normal and critical, the internal diaphragm of the sensor will move to the original position so that the switch will automatically reset, and then through the dedicated CPU modular signal processing technology to realize the detection of the medium pressure signal, display, alarm, and control signal output to avoid unnecessary safety hazards.
