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.

摘要： The invention relates to a pressure sensor element to be mounted in a connection element (40), comprising a separating body (10) with a laterally protruding diaphragm (20). Said diaphragm (20) covers an opening of a passage (12) through which the pressure acting on the diaphragm (20) is transferred to a pressure transducer element (30) by means of a transfer medium (32). For the purpose of mounting, the pressure sensor element is fixated in a mounting opening (42) of a connection element (40). The protruding edge of the diaphragm (20) is fastened on the surface (41) of the connection element surrounding the mounting opening (42) by means of a self-contained connecting seam (44). It is also possible to use a conventional diaphragm, combined with a diaphragm ring, instead of the protruding diaphragm, said diaphragm ring covering a gap between the pressure sensor element and the connection element.

摘要： The invention relates to a transmitter comprising a measuring sensor (1) which is used to detect a physical measuring variable (X) and to convert the same into an electrical variable; a signal pre-processing device (3) which is used to convert the electrical variable into a raw signal (R); a signal processing device (4) which is used to convert the raw signal (R) into a measuring signal (M); and an output stage (7) which is used to emit an output signal corresponding to the measuring signal (M). Errors occurring during the processing of the raw signal (R) can be identified by the monitoring unit (9) of the transmitter, which, during operation, compares the output signal with an auxiliary signal (H) derived from the raw signal, and triggers a security-oriented adjustment of the output signal when a difference between the output signal and the raw signal (R) exceeds a pre-determined limit.
