Zusammenfassung:	PCT No. PCT/EP96/01807 Sec. 371 Date Dec. 16, 1997 Sec. 102(e) Date Dec. 16, 1997 PCT Filed Apr. 30, 1996 PCT Pub. No. WO97/00433 PCT Pub. Date Jan. 3, 1997A device for measuring various fluid pressures, the device includes a sensor plate which has fastening holes, which are distributed in matrixlike fashion over the sensor plate. Measuring diaphragms, which form end walls of blind bores in the sensor plate, are located between the fastening holes. Through fluid conduits of a hydraulic block to which the sensor plate can be secured, the measuring diaphragms can be acted upon by pressure. The evaluation is done with four strain gauges applied to each measuring diaphragm, the strain gauges being interconnected to form a Wheatstone bridge. Because it is possible to mount the sensor plate in a way that optimizes strain, it is possible to measure various pressures with minimal measurement error using one sensor plate.
