Beck 930 Series Differential Pressure Switch With UL Approval with UL approval adjustable from 20 to 5000 Pascal

A versatile differential pressure switch designed to monitor overpressure, vacuum, and differential pressure in air or other non-combustible, non-aggressive gases. Its switching pressure is adjustable via a scaled adjustment knob, eliminating the need for a pressure gauge. Available in multiple versions with adjustable ranges from 0.2 mbar to 50 mbar, ensuring flexibility for different applications. Equipped with a transparent cover meeting IP54 protection standards as standard.

Applications

  • Monitoring air filters and ventilators
  • Monitoring industrial cooling-air circuits
