Abstract
A separating membrane for use particularly in pressure sensors, for separating between a process fluid and a pressure-transferring hydraulic oil, is described. The separating membrane is in the form of a thin foil covering an opening into a volume containing the oil, with the foil being fastened to the edges of the opening, and is characterized in that the separating membrane is fastened at the edges of the opening in such a manner that it, in at least one region of its area, exhibits a transition from a concave to convex bulging, whereby the membrane is able to accommodate a volume change of the oil through a non-energy requiring translation of the transition(s). Also described are a method of manufacturing the separating membrane as well as a pressure sensor comprising the separating membrane.
