Description
Diaphragm seals are used for the protection of pressure measuring instruments in applications with difficult media. In diaphragm seal systems, the diaphragm of the diaphragm seal effects the separation of the instrument and the medium. The pressure is transmitted to the measuring instrument via the system fill fluid which is inside the diaphragm seal system.
For the implementation of demanding customer applications, there is a wide variety of designs, materials and system fill fluids available.
For further technical information on diaphragm seals and diaphragm seal systems see IN 00.06 "Application, operating principle, designs".
The model 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, inline 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, Bio Processing 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.
