How do you know about the working principle of the pressure switch?

The working principle of the pressure switch is that if the pressure inside the system is higher or lower than the initial set safety pressure value, the disc of the sensor inside the pressure switch can be sensed in time and an alarm is issued, which also occurs. The movement, through the interconnection with the guide rod, causes the connection of the pressure switch to be powered on or disconnected from the power source. It should be noted here that when selecting the pressure switch, Xiaobian suggests that you understand whether the pressure of the pressure is pulsating or not, and you do not need to use the throttle valve, which will lose the instrument!
