Adjustable differential pressure switch for monitoring overpressure, vacuum and differential pressure of air or other non-combustible, non-aggressive gases.
The switching pressure can be adjusted without a pressure gauge using a scaled adjustment knob. Various versions with overlapping adjustment ranges between 0.2 mbar and 50 mbar are available for this purpose. As standard, the pressure switch is equipped with a transparent cover of protection class IP54.
