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 fluid is located inside the diaphragm seal system. There are a wide variety of designs, materials, and system fill fluids available for demanding applications.
The model 990.10 diaphragm seal with threaded connection in threaded design is suitable for versatile application areas. A replacement of the lower body is possible without modifications on the diaphragm seal system. High pressure ranges up to 250 bar can be covered.
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 diaphragm seal and the wetted parts can be made of identical or different materials. The wetted parts can be coated.
