Abstract: A replaceable seal system with high and low sides connectable to a coplanar inlet plate on a pressure transmitter. A first side of the seal system can be replaced without disturbing the sealing of a second side of the seal system. The seal system includes a stack of first and second plates with a central split line. At least one of the first and second plates is split along the central split line to provide for separate replacement on only one side of the system.

Abstract: The present disclosure is provided with a measuring element (M) and a measuring device. The measuring element includes a base body, a diaphragm and a permeation resistant layer, the diaphragm is fixedly connected to the base body, with a sealed cavity being defined between the diaphragm and the base body. The permeation resistant layer is arranged on an inner side surface, facing the sealed cavity, of the diaphragm, and extended continuously on the inner side surface of the diaphragm at least beyond a connection region of the diaphragm with the base body. The measuring device includes the measuring element (M).
