摘要： A multi-component dynamometer for measuring forces and torques includes two force introduction plates and pre-oriented transducer elements without housing arranged between them. Each transucer element comprises typically a rectangular plate and two pre-oriented piezoelectric elements fixed thereon, one of these being sensitive to shear in a direction parallel to one edge of the carrier plate and the other being sensitive to pressure in a direction parallel to the normal of the carrier plate. The pre-oriented transducer elements enable the number of piezoelectric elements and electrical connections to be reduced substantially when assembling measuring platforms, as well as the amount of orientation and testing work. The platforms can be made flatter and more rigid, thereby raising the natural frequency. The electronic measuring and evaluation parts can be integrated partially or wholly into the dynamometer.

摘要： A transducer, particularly for ballistic high pressure measurements, comprises an assembly body, with a shoulder sealing section and a sensor member, which can be received in a recess in the assembly body. The assembly body can be screwed into a component, e.g. a gun barrel, the measurement area on the sealing section being sealed. The assembly body has a tubular extension extending beyond the sealing section, which extension encompasses the sensor member on a cylindrical fitting face. The high sealing forces required for sealing the measurement area are kept remote from the sensor member. The measuring sensitivity of the transducer is therefore independent of the prevailing tightening torques. A cylindrical gap between the sensor member and assembly body provides additional insulation between the sealing forces and the prestress forces prevailing in the sensor member. The cylindrical gap is sealed against the pressure medium by a force fit or weld between the assembly body and the sensor member. A reception space can be provided ahead of the diaphragm section of the sensor member, which reception space can be formed by an annular section projecting from the diaphragm section, and can be provided with replaceable thermal and erosion protection devices.

摘要： A transducer insert for installing in sensors for measuring mechanical variables includes a semi-conductor body with a measuring diaphragm part of which has diffused-in strain-sensitive resistance paths or capacitor electrodes and also connecting contacts on one side. The semi-conductor body is connected to a base body of insulating material, preferably by an anodic method, through which electrically conductively coated channels pass. The channels open at a recess in the base body which is bridged by the measuring diaphragm part. The electrically conductive layers of the channels extend along the recess to the vicinity of the connecting contacts of the semi-conductor body and are directly connected thereto in an electrically conductive manner by the so-called corner drop method, e.g. by glueing, soldering or thermo-compression. A central projection can be provided in the recess of the base body which creates a deflection limit for the measuring diaphragm part. The transducer insert can be manufactured according to the so-called batch method.

摘要： A piezoresistive transduction element for incorporation into a pressure transducer includes a plate defining a diaphragm zone and preferably of silicon with piezoresistances diffused into it, an insulating plate of a glass material and a base plate. The plates are preferably connected to each other by anodic connections in a series of steps. The base plate is made of a material having substantially the same coefficient of thermal expansion as that of the material of the plate which defines the diaphragm zone. Furthermore, the dimensions of the base plate are matched to those of the diaphragm plate. By these measures the deformation forces exerted by the base plate and diaphragm plate on the insulating plate upon changes in temperature are of substantially the same magnitude and therefore there is minimum bending of the diaphragm plate. A symmetrical transduction element is created which has minimum zero point displacement and minimum sensitivity changes in use. Pressure transducers equipped with such piezoresistive transduction elements are therefore appropriate for high measuring accuracy, particularly in combination with an improved, elastically extensible securement of a holder which carries the transduction element within the transducer housing.
摘要翻译：用于结合到压力传感器中的压阻转换元件包括限定隔膜区并且优选地具有扩散到其中的压阻的硅的板，玻璃材料的绝缘板和基板。板优选通过一系列步骤中的阳极连接彼此连接。基板由具有与限定隔膜区域的板的材料基本相同的热膨胀系数的材料制成。此外，基板的尺寸与隔膜板的尺寸相匹配。通过这些措施，温度变化时由基板和隔膜板施加在绝缘板上的变形力基本上是相同的大小，因此隔板的弯曲最小。创建了一个对称的转导元件，其具有最小的零点位移和最小灵敏度的使用变化。因此，配备有这种压电转换元件的压力传感器适用于高测量精度，特别是与在换能器壳体内承载换能元件的保持器的改进的可弹性伸展的固定件相结合。
