Sensor arrangement for force or pressure measurement, particularly for integrating in fuel injector, comprises sensor element, which is made of piezoelectric material with two parallel front surfaces

摘要

The sensor arrangement comprises a sensor element (1), which is made of piezoelectric material with two parallel front surfaces (1.1,1.2), from which each forms or incorporates electrodes (3,4,5). The sensor element is provided with the latter front surface for forming or incorporating the electrode that directly or indirectly adjoins to the front surface (2.1) of another sensor element (2). The latter sensor element is made of piezoelectric material with two parallel front surfaces (2.1,2.2).
