Abstract: An evaluation apparatus and a method for determining a characteristic variable for the location of a boundary surface in a container are described, wherein a multiple echo having at least the order of one is recognized in an echo curve. The characteristic variable for the location of the boundary surface in the container is determined based on the position of the multiple echo and the order of the multiple echo.

Abstract: A transit-time fill-level measuring device for measuring the fill level of a filling material in a container is stated, in which transit-time fill-level measuring device information about the topography of the filling material surface is determined on the basis of the shape of a single echo curve of the receiving signal. From this the fill volume can then be derived.

Abstract: The invention is a vibration sensor with a carrying element capable of being set into vibration; a conversion device having a field coil to set and/or tap the carrying element into vibration; an anchor mounted in the field coil; and, a vibration element to transmit the vibrations from the carrying element into/from a surrounding space. The anchor is designed as two parts, having a permanent magnet and a coil core connected to the field coil, with an air gap arranged therebetween and lying in the area of the axial extension of the field coil. The permanent magnet is connected to the carrying element to transmit vibrations; and, the field coil and the permanent magnet are arranged to interact in such a way that any vibration of the permanent magnet induces current flow in the field coil and/or induces vibration of the permanent magnet in the field coil.

Abstract: Measuring a fill level or limit state is performed using an electromagnetic vibrating system, in which a transmission signal(s) is generated. A vibrating body (20) is excited into a state of vibration by the transmission signal (s); and by means of the reception signal (e) that is then produced by the vibrating body (2) the transmission signal (s) is modified for at least one subsequent excitation of the vibrating body (2), while a natural frequency (fe) of the vibrating body—or a magnitude (te) dependent on the natural frequency (fe)—is determined from the reception signal (e), and the transmission signal (s) is thereby modified.

Abstract: Described is diagnosing radiometric detectors. The pulse amplitudes of the pulses acquired by the radiometric detector can be measured and stored temporarily. The pulse amplitude distribution determined in this manner is compared to a reference amplitude distribution, whereby error diagnosis and, if applicable, recalibration of the measuring device are made possible. In this manner temperature drifts and damage to the scintillator, EMC radiation and an increased rate of dark pulses of the photosensitive component may be detected and corrected.

For the purpose of transmitting the signals, the interface connection and the radio interface are coupled to each other so as to be able to communicate.

Abstract: A field device acquires measured values and transferring data in an energy-controlled manner. A control device monitors the quantity of energy collected in the field device and triggers data transfer only when the quantity of energy collected has exceeded a predetermined threshold value. In particular, data transfer can take place at irregular intervals.
