Beck – ATEX Differential Pressure Switch 930EX Climair


Beck – ATEX Differential Pressure Switch 930EX Climair


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

This pressure switch can be used in hazardous & 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.
