Diaphragm seals

The optimal diaphragm seal for every process

WIKA diaphragm seals (often also referred to as chemical 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 -90 to +400 °C 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.

What are the characteristics of an in-line diaphragm seal?

The in-line diaphragm seal is perfectly suited for use with flowing media. With the seal being completely integrated into the process line, measurements do not cause any turbulence, corners, dead spaces or other obstructions in the flow direction.
