Description
Diaphragm seals are used for the protection of pressure measuring instruments in applications with difficult media. 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. This is located inside the diaphragm seal system.
There are a wide variety of designs, materials, and system fill fluids available.
The model 990.35 diaphragm seal is available for all commonly used standard flanges together with a blind flange. The diaphragm seal can be used at thick-walled or insulated locations in pipeline and vessel construction due to extended diaphragm.
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 extension and the wetted parts can be made of identical or different materials. The diaphragm and the extension can be coated.
