| 20110094299 | Method for evaluating the measurement signals of a propagation-time based measurement device - A method which allows especially the extrapolation of the measured value at the upper and lower end of a measuring range where normally no direct measurement range where normally no direct measurement is possible by superposition of interfering signals, for example by reflection on a radar antenna. In the presence of strong interference signals, for example by reflection of a radar antenna. In the presence of strong interference signals, which are for example caused by the natural resonance of the container or neck in which the measuring device is mounted, the direct level indicator signal can be regularly used if it has a high amplitude caused by a superposition with the interfering signal lies between two interfering signals and does not extend beyond these, the level indicator value can be interpolated by the shift of the signals from the point of reflection. The inventive method automatically adapts itself to a prevailing measuring situation while according to known methods for the user has to decide between a measurement via a shift of EOL signal or a measurement via the direct level indicator echo. | 04-28-2011 |
| 20100309600 | APPARATUS FOR DETERMINING AND/OR MONITORING A PROCESS VARIABLE - An apparatus for determining and/or monitoring at least one process variable. The apparatus includes at least one relay, at least one voltage source, and at least one voltage increasing unit. The relay, the voltage source and the voltage increasing unit as embodied, are matched to one another, and are connected with one another in such a manner that, when the voltage source supplies the relay with voltage for pull-in of the relay, the voltage increasing unit causes such an increase of the voltage applied to the relay, that the applied voltage corresponds at least to the pull-in voltage of the relay. | 12-09-2010 |
