Pressure Switch

Product Details:

Applications:Adjustable differential pressure switch for monitoring over pressure, vacuum and differential pressure of air or othernon-combustible, non-aggressive 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
The switching pressure can be adjusted without a manometer at the adjustment knob with the guide value scale. Various versions are available for this with overlapping adjustment ranges of between 0.2 mbar and 50 mbar. The pressure switch is equipped as standard with a transparent cover, protection class IP54.
Diaphragm material: Silicone, tempered at 200°C, free of gas emissions, Other materials available on request.
P1 for connection to higher pressure (marked +)P2 for connection to lower pressure (marked –)
Electrical connections: AMP flat plug 6.3x0.8 mm in accordance with DIN 46244 or push-on screw terminals, Cable conduit with cable strain relief.

Product Details:

Adjustable differential pressure switch for monitoring over pressure, 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, 2 and 21, 22 with ATEX type examination

The switching pressure can be adjusted without a manometer at the adjustment knob with the guide value scale. Various versions are available for this with overlapping adjustment ranges of between 0.2 mbar and 50 mbar. The pressure switch is equipped as standard with a transparent cover, protection class IP54.


Ex i-circuits:
This pressure switch can be used in potentially explosive zones1, 2 and 21, 22. 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 inherentsafety. For this purpose, the power specifications (P, I, U) of thebarrier must be lower and the characteristics (L, C) higher thanthose of the pressure switch and of the connection line (blue colour).
