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 990.36 small diaphragm seal with threaded connection and flush diaphragm is suitable for versatile applications. This diaphragm seal, despite its compact dimensions, can also be used for high pressures.
Optionally, there are versions available in hygienic design or with protective plates.
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 diaphragm seal and the wetted parts can be made of identical or different materials. The wetted parts can, as an alternative, be coated.
