Smc pneumatic pressure switch in the said positive pressure is what it means
Pneumatic pressure switch, that is, to check the positive pressure range of the [positive pressure switch], but also to detect the negative pressure range of the [vacuum pressure switch].
[Positive pressure switch] The use of pressure sensor principle, automatically detect the pneumatic system is too high or too low positive pressure, the controller automatically cut off the circuit, send a signal to ensure the stability of the normal operation of the equipment.
[Vacuum pressure switch] the use of pressure sensor principle, automatic measurement and control system within the vacuum pressure to ensure that equipment in the unattended, accurate and stable automatic operation control.
Pneumatic vacuum switches are also a pressure protection device for vacuum systems. When the vacuum pressure in the system is greater than or less than the set point, the circuit can be automatically cut off, send a signal to ensure the normal operation of the system.
Pneumatic pressure switch is a combination of air pressure and electrical switch device. When a pre-set (or fixed) gas pressure is detected, the switch contacts are actuated. Output device control signal or alarm signal, can control the normal operation of the equipment or prevent the destruction of production equipment and equipment to avoid accidents and so on.
