摘要： An electromechanical transducer with at least one piezoelectric element with a first surface on which a first electrode is applied, and at least one contact flag, through which the piezoelectric element is electrically connected. The electrical connection of the piezoelectric element is of very high contact reliability, in that the contact flag directly contacts the first electrode and exhibits at least one depression, into which an adhesive is placed, by which the contact flag is connected with the electrode.

摘要： A dry, front-flush, pressure measuring transducer, which enables reliable measurements over a large temperature range. The transducer includes: a process connection made of a stainless steel and serving for securing the pressure measuring transducer to a measuring site; and a pressure sensor module, including a holder of stainless steel, into which a metal separating diaphragm is set front-flushly by means of a purely metal connection. A pressure to be measured acts on the separating diaphragm during measurement operation. The holder is set front-flushly by means of a purely metal connection into the process connection. The pressure sensor module further includes a titanium disk which is carried by the holder. A sapphire carrier with integrated silicon sensors is secured to the titanium disk. The titanium disk forms the separating diaphragm or it is physically connected with the separating diaphragm in such a manner that a deflection of the separating diaphragm effects a corresponding deflection of the titanium disk.

摘要： Device for determining and/or monitoring the weight of a medium (1) in a container (2) comprises a level measuring unit (3) for determining and/or monitoring the level of the medium, a density measuring unit (4) for determining and/or monitoring the density of the medium and an evaluation unit (5) for determining the weight of the medium from the level and the density of the medium. Preferred Features: A temperature measuring device (6) determines and/or monitors the temperature of the medium. The evaluation unit uses the temperature of the medium during the determination of the weight or mass flow. A storage unit (7) stores data for determining the volume of the medium in the container depending on the level.

摘要： The unit has segments (2) with different polarization symbols and connected with electrodes (3). A varistor layer (4) with different electrical symbols is situated between the electrodes, where an electrical resistance of the layer depends on a voltage applied on the unit. The resistance of layer automatically changes itself, so that the layer short circuits the segments when high voltage is built up in the unit. An independent claim is also included for a manufacturing method for a piezoelectric unit that is utilized for producing and/or receiving mechanical vibrations.

摘要： An assembly (1) monitors the progress of an industrial process in which a medium is modified by a physical or chemical process. The assembly has a probe (5) that transmits or receives oscillations. The assembly has a stiffness adjustment unit (20) that regulates the resonation frequency. The adjustment unit is a piezoelectric device with electrodes, whose frequency is altered by variation of electrical current between electrodes (21). The resonance is adjusted by variation of a magnetic field. An independent claim is included for a process to alter the resonating frequency.

摘要： Method for manufacture of a vibrating measurement device, e.g. a measurement fork, for measuring a physical variable of a system, e.g. the liquid level in a tank. According to the method, the mechanical vibration capable unit is set in vibration and the reaction forces and reaction moments caused by the vibration of the mechanical unit against its clamping support. If the forces and or moments exceed a defined limit, then a warning is generated and the vibration properties of the device are changed. The invention also relates to a corresponding device for manufacturing a measurement device.
