SEPARATING MEMBRANE FOR HYDRAULIC PRESSURE TRANSMITTERS AND PRESSURE TRANSMITTERS AND MANOMETERS COMPRISING SAID SEPARATING MEMBRANES

摘要

A separating membrane (7) for transmitting a pressure comprises a flexible membrane body (9), containing stainless steel, and a ceramic cover layer (10). The invention is characterized in that the ceramic cover layer, apart from an interposed adhesive layer which can be optionally provided, is directly applied to the stainless steel of the membrane body (9). The cover layer especially comprises Al₂O₃.
