  • Patent number: 9459132
    Abstract: To detect a limit level, a multi-limit level measuring device is employed, which uses two different measured data evaluation methods. The measured data to be evaluated is acquired by a multi-limit level sensor arrangement which can use different physical measurement principles. In this manner, the likelihood of the limit level being erroneously detected may be reduced.

  • Publication number: 20160054167
    Abstract: For determining the topology of a bulk material surface, a series of echo curves are detected in different primary radiation directions of the antenna. In the process, the primary radiation direction of the antenna is changed in such a way that all of the generated echo curves of the series of echo curves can be used for determining the topology of the bulk material surface. As a result, the measurement time can be reduced.

  • Publication number: 20160025582
    Abstract: The invention relates a capacitive pressure transducer for measuring the pressure of a medium adjacent to the pressure transducer, which has a resilient measuring diaphragm, of which the first side is at least partially in contact with the medium and of which the second side, which faces away from the medium, comprises a measuring electrode and, for measuring the temperature, a resistance element made of a material having a temperature dependent resistance. Furthermore, the pressure transducer has a base body, which is arranged opposite the second side of the measuring diaphragm, with a counter electrode, which forms a measuring capacitance with the measuring electrode. According to the invention, the resistance element is formed as a resistive layer between the second side of the measuring diaphragm and the measuring electrode.

  • Publication number: 20140340259
    Abstract: For determining the topology of a bulk material surface, a series of echo curves are detected in different primary radiation directions of the antenna. Subsequently, for each distance cell of the echo curves, the maximum of all of the echo curves is determined and the distance thereof is plotted as a function of the coordinates thereof so as to obtain an image of the topology of the bulk material surface in two or three dimensions.

  • Patent number: 8711049
    Abstract: For safety reasons the potential of an electrical supply line of a radar sensor should be separate from the potential of the filling level container. An arrangement for potential separation for a filling level radar is provided, which arrangement comprises a separation element for insulating the waveguide from the antenna. The separation element, corresponding to the cross section of the waveguide, is ring shaped. In this way rotatability between the sensor housing and the antenna subassembly is provided without influencing the signal line between the antenna and the waveguide.

  • Patent number: 8604414
    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.
