摘要： The electronic switching device serves to control the connection of a load to a voltage source by a switch which is controlled in a first operating mode directly by a binary signal furnished by a signal processing circuit and in a second operating mode inverted. The switching device has three terminals, of which the first permanently remains connected to a first terminal of the voltage source and to a first terminal of the load, whilst of the other two switching device terminals the one is connected to the second terminal of the voltage source and the other to the second terminal of the load. The switching device is configured so that it can be changed over from the one operating mode into the other by interchanging the connections between these two other switching device terminals and the second terminals of the voltage source and of the load, respectively.

摘要： The device for determining and/or monitoring a predetermined filling level in a container has two oscillatory rods secured with spacing adjacent one another on a diaphragm the edge of which is connected to a screw-in part. By means of the screw-in part the device is so secured in a screw-threaded aperture of the container wall at the height of the filling level to be detected that the oscillatory rods project into the container. At the side of the diaphragm remote from the oscillatory rods a bridging member is held spaced from the diaphragm by flexurally elastic rod-shaped supports. Each of the rod shaped supports is rigidly connected at one end to an oscillatory rod. Between the bridging member and the diaphragm there is held, with preloading of the diaphragm, a transducer column comprising in a stack a piezoelectric excitation transducer and a piezoelectric reception transducer. The piezoelectric transducers are connected to one another via an amplifier in a self-excitation circuit so that the mechanical oscillatory system is excited with its natural resonance frequency. An evaluation circuit responds to changes in frequency of the oscillations and initiates indicating and/or switching operations in accordance with such frequency changes.

摘要： An apparatus for determining and/or monitoring at least one fill level of a medium in a container comprising: a capacitive or conductive probe unit having at least one electrode; and a control/evaluation unit. The electrode is a hollow body, that an end region of the electrode protruding into the container is embodied as an oscillatable membrane. On an inner side of the membrane a driving/receiving unit is arranged, which excites the membrane to execute mechanical oscillations and receives mechanical oscillations therefrom and converts such into an electrical, received signal. The control/evaluation unit supplies the electrode at least at times with a voltage and determines the fill level of the medium capacitively or conductively, and/or that the control/evaluation unit supplies the driving/receiving unit at least at times with an exciter signal and determines from the electrical received signal the fill level of the medium.

摘要： A method and an apparatus for determining at least one flow characteristic of an essentially laminarly flowing, gaseous or liquid medium in a pipeline. Distinguishing features include: that at least one modulation element introduced into, or placed in, the pipeline produces, at least for the case, in which the medium is flowing with a velocity different from zero, a change in density of the medium, at least at times, in the vicinity of the modulation element; that at least one mechanically oscillatable unit introduced into, or placed in, the pipeline and spaced from the modulation element is excited to resonant oscillations; that mechanical oscillations are received by the mechanically oscillatable unit and converted into an electrical, received signal, wherein the received signal is sensitive to the density change; and that the at least one flow characteristic of the medium is determined from the reaction of the received signal of the mechanically oscillatable unit to the density change.
