Pressure switches Bourdon

Bourdon

Bourdon-Haenni is one of the world leading brands for mechanical process instrumentation and belongs with its international business locations to the Baumer Group. Historically, this competence and passion is based on the Bourdon tube invented in 1843 by Eugène Bourdon, which is the central component for precise mechanical pressure measurement technology, today and in the future. Bourdon provides various pressure measuring technologies on mechanical instruments.

Mechanical pressure switches have been developed to switch an electrical contact, when a pressure in a process exceeds defined limits. The pressure can be too high or too low. Pressure switches have no precise local indication, no analog output signal and need no electrical power supply. These simple devices are purely optimized to guarantee an excellent repeatability and reliability of the switching behavior.

Pressure switches without power supply are used in safety critical applications. Bourdon is a well- known supplier for the equipment of power plants and offers a wide range of products especially for nuclear power stations. But also many other applications like monitoring of pressurized chambers, tank levels, valves, compressors profit from these safe and simple solution.

Pressure switches are available in EEx ia and EEx d versions for hazardous areas. Assembled with diaphragm seals pressure switches can be used also in applications with critical process fluids or for hygienic installations in food or pharma production.
