990.40 Threaded Connection Diaphragm Seal
2249
The WIKA 990.40 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. With this diaphragm seal, low-pressure ranges can be covered ” the large diameter of the diaphragm affects a lower deviation at the measuring instrument when the temperature changes. 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 coated.
