The video isn't a tutorial, but is a demonstration. If I am not wrong, the vacuum switch is assigned a pre-set value, and it has the ability to measure the pressure. If the pressure falls below the preset value significantly, the vacuum switch will turn on the solenoid valve. The solenoid valve, when turned on, allows the pressurized air through. When the pressure reaches the preset value, the vacuum switch turns off the solenoid valve, which blocks off the air supply. Of course, the negative pressure is generated by the vacuum ejector.

Do you know the model of the sensor?
How to set real value and set value sir
No help, thumbs down
