The WIKA high-quality BA/BAX bourdon tube pressure switch is developed for safety-critical applications. The high quality of the WIKA BA/BAX bourdon tube pressure switch is following ISO 9001, which ensures 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. By using a bourdon tube measuring system, the WIKA BAX and BA pressure switch is extremely robust and guarantees optimal operating characteristics. To ensure as flexible operation as possible, the pressure switches are fitted with micro switches, which enable the switching of an electrical load of up to AC 250 V, 20 A directly. For lower switching power ratings, such as for PLC applications, argon gas-filled micro switches with gold-plated contacts can be selected as an option. For applications with special requirements on the wetted parts, versions with materials from PTFE, Monel or Hastelloy are available. By using a diaphragm measuring system, the WIKA BA/BAX bourdon tube pressure switch is extremely robust and guarantees optimal operating characteristics. For setting ranges from 4 … 40 bar a piston replaces or completes the diaphragm as a measuring element. The wetted parts of this variant from stainless steel are particularly suited for liquid media.

The SIKA VH780 flow switch monitors the flow of low-viscosity media in pipes. The SIKA VH780 offers a reliable solution for ensuring the minimum flow rate and thereby protecting high-quality systems and installations from damages. These flow switches work based on the well- established mechanical operating principles. Thanks to the different paddle lengths, the switch points of the paddle flow switches can be configured for a wide switching range. The flowing medium hits the plate secured to the end of a paddle. The resulting dynamic pressure causes the paddle to travel. This, in turn, causes the actuation of a micro switch. The flowing medium hits the plate secured to the end of a paddle. The resulting dynamic pressure causes the paddle to travel. This, in turn, causes the actuation of a micro switch.
