摘要： A piezoelectric sensor, preferably a pressure sensor, comprising at least two piezoelectric measuring elements placed in a housing, which are clamped between a membrane on the pressured side of the housing and a pick-up electrode electrically insulated against the housing. The piezoelectric measuring elements are fixedly attached to the pick-up electrode by thermo-compression or soldering and together with said pick-up electrode form a compact measuring element stack, which will significantly simplify assembly of the piezoelectric sensor.

摘要： The invention relates to a glow plug with integrated pressure sensor for measuring pressure in the combustion chamber of an internal combustion engine, where the shell of the glow plug has a section of reduced diameter on the side next to the combustion chamber and following a sealing cone, which section houses a glow coil and ends in a tip extending into the combustion chamber, and where the pressure sensor is positioned without cooling in the section of the glow plug next to combustion chamber. According to the invention the pressure sensor is subjected to pressure in radial direction, the glow coil of the glow plug or the electrical leads of the glow coil being guided towards the tip of the glow plug either by bypassing the pressure sensor or going through the pressure sensor.

摘要： A sensor element (1) has at least one measurement element (2) with piezoelectric and pyroelectric properties, and measurement electrodes (3). A measurement variable and a disturbance variable act simultaneously upon the at least one measurement element (2) and the measurement signal derived from the measurement electrodes (3) includes an interference signal. The sensor element (1) has at least one compensation element (4, 4′) upon which only the disturbance variable acts, so that a correction signal used to compensate for the interference signal in the measurement signal can be derived from the compensation element (4, 4′). The invention consists in that the compensation element (4, 4′) is in thermal contact with a first support (10) and with a second support (11) of the measurement element (2), or with the measurement element (2), over its length between the supports (10, 11), so that substantially the same temperature field is established in the measurement element (2) and in the compensation element (4, 4′).
