FAQ

Question?

What is the switching function of the PEV-1/4-B-OD?

This pressure switch functions as a changeover switch, providing both normally open (NO) and normally closed (NC) contacts.

How do I adjust the switching pressure point on this device?

The switching pressure is adjusted using the setting screw, which is typically located under the protective cap. Turning the screw changes the pre-tension on the internal spring, thereby setting the pressure threshold.

Is this pressure switch suitable for use with vacuum?

No, the specified operating range is from 1 to 12 bar. It is designed for positive pressure applications and is not suitable for measuring or switching at vacuum levels.
