Diaphragm seals

WIKA diaphragm seals, mounted with pressure gauges, process transmitters, pressure switches etc., are recognised and valued internationally for the most difficult of measuring tasks. By using diaphragm seals, the measuring instruments can be used at extreme temperatures from  -130 to +750 °F and with aggressive, corrosive, heterogeneous, abrasive, highly viscous or toxic media. The optimal diaphragm seal designs, materials and filling media are available for each application.

FAQ
All FAQ

When should a diaphragm seal be fitted?

Diaphragm seals are used for pressure measurements when the process medium should not come into contact with the pressurised parts of the measuring instrument or if adjustment to the harsh conditions of a process is needed.

How are diaphragm seals integrated into processes?


Diaphragm seals are mounted to existing connecting flanges or welding sockets, which are welded to a pipeline, a process reactor or a tank.
