Pressure sensor assembly and transducer for process instrumentation with such a pressure sensor assembly

The invention relates to a pressure sensor assembly having a tube (2) is arranged in its cross section a with the pressure to be measured is acted upon membrane (1). The membrane (1) is mounted extending on the tube inner wall by means of a along the peripheral portion of the diaphragm (1) the joint (5). A deformation of the membrane (1) leads to a rotation of the articulation (5) directly on the wall of the tube (2) and can therefore be detected from the outside by appropriate means (7, 8). This has the advantage that, for example strain sensors (7, 8) which can be used for detecting deformation are not in contact with the process medium and no pressure-tight passage for electrical signals is required. The pressure sensor assembly is characterized by a particularly simple construction and is advantageous for transmitters to process instrumentation used.
