摘要： A method for ascertaining and monitoring the fill level of a medium in a container via a field device, wherein transmission signals are transmitted toward the medium and are received as reflection signals. The transmission signals and the reflection signals are registered by means of data points in an envelope curve dependent on travel time or travel distance. Disturbance echo signals are registered by means of data points in a masking curve, the data points are connected with one another via connecting functions An evaluation curve is ascertained from the envelope curve; wherein, by means of a reduction algorithm, the number of data points in the masking curve and/or in the evaluation curve is reduced; and wherein, by an echo search algorithm, by means of the reduced masking curve and/or reduced evaluation curve, at least one wanted echo signal in the current envelope curve is ascertained.

摘要： A method for checking proper functioning of a fill-level measuring device working according to the travel time principle. For this purpose, in predetermined or selectable time intervals (ta), a current measured value curve at a current fill level (hactual) is ascertained; on the basis of the current measured value curve, a current wanted echo signal is determined. Subsequently, on the basis of the current wanted echo signal, an expected value (E) for quality of a wanted echo signal at at least one predetermined fill level (hdesired) is ascertained. The ascertained expected value (E) for quality of the wanted echo signal at the predetermined fill level (hdesired) is compared with a predetermined critical value for quality, and an error condition is diagnosed, when the ascertained expected value falls below the critical value for quality.

摘要： In order to provide a microwave-conducting arrangement, which is relatively easy, and thus cost-favorable, to fabricate, and which is suited also for complex structures and geometries, one or more electrically conductive layers are provided which are applied on a non-conductive body having a surface of any shape. A metallizing provided for such purpose on the surface of the body is, for example, produced by a vapor-deposition process, by means of a flame-spraying process, or by means of a chemical metallizing.

摘要： An electronic device including electronics arranged in an electronics compartment and having electronic and/or electromechanical components. The device automatically detects and/or monitors wear of its electronic and/or electromechanical components and includes an apparatus for detecting and/or monitoring wear of the electronic and/or electromechanical components. Included is at least one element arranged in the electronics compartment. This element is independent of the electronics and has at least one physical property, which changes irreversibly as a function of wear of the element. The apparatus further includes a circuit for measuring the physical property, and an evaluating unit, which, based on the measured physical property, detects and/or monitors wear of the element and makes available a wear-dependent output signal.
