981.22 In-Line Diaphragm Seal

The WIKA 981.22, 981.52 and 981.53 in-line diaphragm seals are suitable for use in the measurement of flowing media. In addition to avoiding potential blockages in the process, in-line measurement technology also contributes to securing product quality, mainly through its perfect cleanability.

The WIKA 981.22, 981.52 and 981.53 in-line diaphragm seals are suitable for use in the measurement of flowing media. In addition to avoiding potential blockages in the process, in-line measurement technology also contributes to securing product quality, mainly through its perfect cleanability.

Due to the continuous cylindrical diaphragm, the measuring locations feature neither dead spaces nor non-flushable branches. The good cleanability of the in-line diaphragm seals has been tested and confirmed by independent institutions (e.g. EHEDG, BioProcessing Institute). The diaphragm seals 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.

Mounting of the diaphragm seal to the measuring instrument may be made via a direct connection, for high temperatures via a cooling element or via a flexible capillary.

The availability of in-line diaphragm seals for common pipe standards and nominal widths simplifies integration into already existing pipe cross-sections.
