摘要： A pressure measuring cell (20) has an elastic measuring membrane (21), wherein a first pressure can be applied to the measuring membrane (21) on a first side and a second pressure can be applied on a second side facing away from the first side. The measuring membrane can be deflected on the basis of a difference between the first pressure and the second pressure. The measuring membrane pressure-tightly separates a first volume, which faces the first side of the membrane, from a second volume, which faces the second side of the measuring membrane. The pressure measuring cell additionally has a transducer for converting the pressure-dependent deflection of the measuring membrane into an electrical or optical signal. The pressure measuring cell is characterized in that, at least in a radial peripheral region (24) in which tensile stress maxima occur in the deflected state of the measuring membrane under application of pressure, the measuring membrane has compressive stresses in the equilibrium state of the measuring membrane, at least at the surface of the measuring membrane.

摘要： Disclosed is a pressure sensor comprising a housing (1) which has a housing axis and in which a measuring cell chamber is defined that can be impinged upon by a pressure via an opening, said opening being surrounded by an annular first sealing surface. The inventive pressure sensor further comprises a pressure measuring cell (2) that is provided with a second sealing surface facing the opening and a stop surface facing away from the sealing surface, a sealing ring (3), and a clamping device (4) which engages into the housing. The pressure measuring cell and the sealing ring are clamped between the clamping device (4) and the first sealing surface by means of an axial clamping force in such a way that the sealing ring (3) is disposed in a pressure-proof manner between the first sealing surface and the second sealing surface. The pressure sensor also comprises a compensating arrangement encompassing a first transmitting element (7) that faces the opening and a second (4) transmitting element which faces away from the opening. The axial clamping force is transmitted from the clamping device to the pressure measuring cell by the compensating system while the first transmitting element can be tilted relative to the second transmitting element about two axes that run perpendicular to each other.

摘要： The aim of the invention is to minimize the tensioning error of a pressure sensor comprising an essentially cylindrical base body and a measurement diaphragm which is mounted on a face of the base body, the pressure-measuring cell being constrained in an axial direction between an elastic sealing ring which rests on the membrane-facing side of the pressure-measuring cell and a supporting ring which supports the rear side of the pressure-measuring cell. Said aim is achieved by matching the sizes of the sealing ring and the pressure-measuring cell in such a way that any deformation of the membrane-facing side of the pressure-measuring cell caused by axial constraining thereof is so small that the tensioning error of the pressure sensor due to a reduction of the axial constraining force by at least 10 percent is less than about 0.02 percent. The geometry of the supporting ring is determined in an iterative manner by means of FEM.
