FEST0 pressure switch 5
A Festo pressure switch is used on a device (model: PEv 1/4). I would like to ask: 1, this switch is high or low pressure when the action you? 2, if you buy a new, how can I set the pressure of its action? Please experience enlighten me. Thank you!
Action pressure can be set, adjust, press or pull out the adjustment knob.
PEV-1/4-B-SA-FESTO Adjustable pressure switch, Germany Festo adjustable pressure switch
Adjustable pressure switch Product use: mainly used for large air conditioning, refrigeration equipment, the system back to the safe working pressure, the need for manual control, equipment began to work to prevent the system pressure is too high to protect the air conditioning and refrigeration system is always safe Working pressure range. How it works: When the pressure inside the system is higher than the safety pressure required by the equipment, the pressure sensor in the control air immediately moves, so that the micro-switch in the controller is disconnected, and the equipment stops working. When the pressure inside the system is To the safety pressure range of the device, the pressure sensor in the controller is reset immediately. However, due to the operation of the self-locking device in the controller, the micro switch can not be switched on. At this time, press the manual button to make the micro switch Connected, the equipment began to work properly.
Usually the pressure of high action But this is normally open or normally closed contact that is obviously there are specific to see you use the environment process can generally set the Festo I think it is pressure to achieve action pressure you gradually increase Look at the work of the equipment can be generally guaranteed to work the minimum pressure
Features:
1, compact and exquisite appearance, easy to install, a variety of wiring, interface type for users to choose.
2, the switch electrical work long life (more than 100,000 times), safe and reliable self-locking device to ensure that the system pressure back to the safe pressure, press the manual button, the equipment can work properly to ensure that the system working pressure in the control state The
3, all stainless steel pressure sensor work reliable, high precision air pressure, the use of international advanced welding process equipment, sealing performance superior, less than one percent of the leak.
4, the work pressure can be manufactured according to the requirements of users (145 ~ 650PSI / 1.0 ~ 4.5Mpa).
