摘要： A differential pressure measuring cell comprises a measuring membrane; two opposing bodies; and one converter. The measuring membrane is arranged between the opposing bodies and is connected in a pressure-tight manner to the two opposing bodies, forming in each case one measuring chamber. The opposing bodies each have a pressure duct through which a pressure can be made to act upon the respective measuring chamber. The converter is provided in order to convert a deformation of the measuring membrane, which deformation is dependent upon a difference between the pressures, into an electrical signal; wherein the opposing bodies each have a chamber section oriented toward the measuring membrane and a rear wall section oriented away from the measuring membrane with, between these, a decoupling chamber. The chamber sections each have an equalizing duct between the measuring chamber and the decoupling chamber, wherein the decoupling chamber has a diameter that is at least as large as the diameter of the measuring chamber.

摘要： A differential pressure measuring pickup comprises a measuring pickup body and a differential pressure sensor. The measuring pickup body has a process interfacing surface with a first pressure input opening and a second pressure input opening. The differential pressure sensor can be loaded with a first pressure through the first pressure input opening and with a second pressure through the second pressure input opening. The first pressure input opening is closed by way of a first separating diaphragm and the second pressure input opening is closed by way of a second separating diaphragm. The first separating diaphragm is sealed with respect to the surroundings by way of a first seal, and wherein the second separating diaphragm is sealed with respect to the surroundings by way of a second seal. The differential pressure measuring pickup is tensioned during measuring operation with the process interfacing surface thereof against a process interfacing flange, wherein at least one plate-shaped spacer element with plane-parallel surfaces is clamped in between the process interfacing flange and the process interfacing surface, which spacer element defines the spacing between the process interfacing surface and the process interfacing flange and limits clamping of the seals between the process interfacing surface and the process interfacing flange.

摘要： A flange-set for a pressure difference measuring transducer with two flanges mountable on external sides of a measuring mechanism of the pressure difference measuring transducer lying opposite one another and containing membranes to be loaded with pressures, as well as a pressure difference measuring transducer equipped with the flange-set. Each of the flanges comprises: a wall, which in the mounted state covers one of the two membranes of the measuring mechanism and encloses a pressure chamber bordering on such membrane. Arranged on a first side of the wall is a first process connection, which includes a pressure duct connection region, in which opens a pressure duct extending through the flange to the pressure chamber. The first process connections are embodied in such a manner that a pressure difference measuring transducer equipped with the flange-set is mountable and connectable via the first process connections (without interpositioning of an adapter) on a process connection, which has a first process connection geometry designed for the connection and mounting of pressure difference measuring transducers with measuring mechanisms having membranes arranged next to one another in a plane.
