Aseptic connection per DIN 11864
WIKA Bulgaria EOOD
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".
Aseptic connections in accordance with DIN 11864 meet a very high hygienic standard. The dead-space free sealing is ensured through a metallic stop and self-centring.
Even with changing medium temperatures, the connection is maintenance-free and does not need to be checked. 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.
Mounting of the diaphragm seal and measuring instrument is made via direct mounting 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 1.4435 (316L) is used as standard material, other special materials are available on request.
