34-ST-03-57 Page 2 Description of Diaphragm Seals Diaphragm seals are traditionally used whe n a standa rd pressure transmitter should not be e xposed to the process pressure directly. Diaphrag m seals typically protect the pressure transmitter from one or more damaging aspect s of the process media.
