BA / BAX Bourdon Tube Pressure Switches

These high-quality pressure switches have been specifically developed for safety-critical applications. The high quality of the products ensures reliable monitoring of your plant. The manufacturer Cella is certified to ISO 9001. In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested.

In order to ensure as flexible operation as possible, the pressure switches are equipped with micro switches, which make it possible to switch an electrical load of up to 15 A / AC 220 V directly. For smaller contact ratings, such as for PLC applications, argon gas filled micro switches with goldplated contacts can be selected as an option. By using a bourdon tube measuring system, the models BAX and BA1 pressure switch is extremely robust and guarantees optimal operating characteristics. 

Features:

  • No power supply needed for switching of electrical loads
  • Robust switch enclosure from aluminium, 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
