VARINLINE® connection
WIKA Bulgaria EOOD
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".
Due to their hygienic process connection, the model 990.24 diaphragm seals are particularly well suited for food production.
VARIVENT® is a registered trademark of the company GEA Tuchenhagen GmbH.
With this diaphragm seal, pressure measuring instruments can be integrated, dead-space free, into a pipeline using a VARINLINE® access unit or in tanks using a connecting flange for VARINLINE® access units. The diaphragm seals can withstand the cleaning vapour temperatures occurring in the CIP and 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.
For the material selection WIKA offers a variety of solutions, in which the upper body of the diaphragm seal and the wetted parts can be made of identical or different materials. The wetted parts can, as an alternative, be electropolished.
