990.22 Pressure interface with WIKA hygiene connector

Description

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

By combining measuring instruments and pressure interfaces, even the most difficult measurement requirements can be met. 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. The type of process connection (threaded, flanged or hygienic) and the basic manufacturing method are important criteria for product differentiation.

The 990.22 is designed for use in sterile processes and is integrated into the process using a clamp connector. This ensures a high cleaning capacity of the pressure interface. Pressure interface systems are resistant to the cleaning vapour temperatures encountered in SIP (sterilisation-in-place) processes, thus ensuring a hygienic connection between the pressure interface and the medium. 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 the choice of material, with the top and the membrane made of the same materials. Stainless steel is the standard material, other special materials are available on request.

Also available in 990.52 and 990.53, which differ in dimensions from 990.22. These can be found on the datasheet.

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