Differential Pressure Switches

Product Details:

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.

NEW: This series is also available with an ATEX type examination.

Application:

• 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

• Temperature range:
  Medium and ambient temperature from –20°C to +85°C
  Storage temperature from –40°C to +85°C
• Diaphragm material:
  Silicone, free of gas emissions.
• Pressure connection:
  2 plastic pipe connection pieces (P1 and P2), external diameter 6.0 mm.
• Electrical rating:
  Standard version: max. 1,5 A (0,4 A) / 250 VAC
  Low voltage version: max.0,1A / 24VDC.
• Electrical connection:
  Tab terminals 6.3×0.8 mm in accordance with DIN 46244 or push-on screw terminals.
  Cable conduit with cable strain relief.
• Protection class:
  IP 54 with cover
