990.17 Sterile Connection Diaphragm Seal

The WIKA 990.17 diaphragm seal with DRD connection fulfils the high standard requirements of sanitary applications. It can be integrated into tanks and storage vessels via a welding flange. The diaphragm seal systems can withstand the cleaning vapour temperatures occurring in the SIP processes and thus ensure a sterile connection between the medium to be measured and the diaphragm seal.

Assembly of the diaphragm seal and measuring instrument is made via a direct assembly as standard or optionally via a cooling element or a flexible capillary.

For the material selection, WIKA offers a variety of solutions, in which the upper body and the diaphragm are made of identical materials. Stainless steel 316L (1.4435) is used as a standard material. Other special materials are available on request.

Measuring systems with the model 990.17 WIKA diaphragm seal are successfully used primarily for hydrostatic level measurement.

Features:

  • Quick cleaning of measuring point, without residue
  • Suitable for SIP and CIP
  • 3-A compliant
