Bourdon Tube Pressure Switch - BA, BAX

Brand: WIKA Alexander Wiegand SE & Co. KG
These high-quality pressure switches have been developed especially for safety-critical applications. 

The high quality of the products and manufacturing in accordance with ISO 9001 ensure reliable monitoring of your plant. In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested.

All wetted materials are from stainless steel as a standard.
Features
  • No power supply needed for switching of electrical loads. 
  • Robust switch enclosure from Aluminum, IP 66, NEMA 4X. 
  • Setting ranges from 0 ... 2.5 bar up to 0 ... 1,000 bar, vacuum ranges. 
  • Repeatability of the set point ≤ 0.5% of span. 
  • 1 or 2 independent set points, SPDT or DPDT, high switching power up to AC 250 V, 20 A.
