    Tips: Digital Pressure Switch Working Principle.

    The digital pressure switch is mainly used to detect the pressure of the relevant detection part. It works by sensing the pressure of the external environment through built-in sensors. When the external pressure value exceeds or falls below the safety critical point, the sensor membrane changes, and then a control signal is sent to guide the switch to change. Therefore, when the ambient pressure returns to normal and critical, the inner membrane of the sensor will move to the original position, making the switch reset automatically, and then detect the medium pressure signal through the special CPU modular signal processing technology.
