| 摘要 |
The invention relates to a pressure sensor arrangement having a tube (2), in the cross section of which a diaphragm (1) is arranged, to which diaphragm the pressure to be measured is applied. The diaphragm (1) is fastened to the tube inner wall by means of an articulation (5) running along the circumferential region of the diaphragm (1). Deformation of the diaphragm (1) results in rotation of the articulation (5) directly on the wall of the tube (2) and can therefore be detected from the outside by suitable means (7, 8). This has the advantage that strain sensors (7, 8), for example, which can be used to detect deformation are not in contact with the process medium and there is no need for a pressure-tight bushing for electrical signals. The pressure sensor arrangement is distinguished by a particularly simple structure and can be advantageously used in measuring transducers for process instrumentation. |
