Adjustable differential pressure switch for monitoring overpressure, vacuum and differential pressure of air or other non-aggressive, combustible gases.

Possible fields of application include:

  • Monitoring air filters and ventilators
  • Monitoring industrial cooling-air circuits
  • Overheating protection for fan heaters
  • Monitoring flows in ventilation ducts
  • Controlling air and fire-protection flaps
  • Frost protection for heat exchangers
  • Ex zones 1 and 2 with ATEX type examination

Ex i-circuits

This pressure switch can be used in potentially explosive zones 1 and 2. In the safe area, an associated isolating means (separating barrier, switching amplifier) must be connected before. The entire isolating circuit must then be proved to keep inherent safety.
For this purpose, the power specifications (P, I, U) of the barrier must be lower and the characteristics (L, C) higher than those of the pressure switch and of the connection line (blue colour).

Characteristics for IIB:
Voltage- Ui 24VDC/30VDC
Current-Ii 100mA/45mA
Capacitance -Ci 0μF
Inductance -Li 0mH

The switching pressure details are referred to a vertical installation position which is also recommended for pressure switches which have their connection ports below. For a horizontal installation position with AMP terminal lugs on top, the switching values are some 20 Pa higher.
The switching pressure can be set without any manometer by an adjusting knob provided with a reference scale. With the aid of a screwdriver, the switching difference can also be adjusted.
