990.29 Pressure interface with WIKA flange

Description

990.29 pressure interface with flange (diaphragm separator) protects pressure measuring instruments in applications with difficult media. The pressure interface affects the separation of instrument and medium.

The pressure is transmitted to the measuring instrument via a filling fluid system within the pressure interface system. A wide range of designs, materials and system fillers are available to meet customer requirements. 990.29 can be used instead of a blind flange and is available for all commonly used standard flanges. The pressure interface can be attached to the measuring instrument by direct connection, or at high temperatures via a cooling element or flexible hose.

WIKA offers different solutions in material selection, where the top, the extended diaphragm and the wetted parts of the pressure interface can be made of the same or different materials. Alternatively, the pressure interface may also have a coating.

Fields of application, applications 990.29

• for aggressive, hot, highly viscous or crystallising media
• Process industry
• thick-walled or insulated pipelines and pressure vessels

Software

All functions of the 990.29 can be controlled with the Diaphragm Seal Calculation Software.

Pressure interfaces are used in conjunction with pressure gauges. Read more about pressure interfaces here.
