    摘要： Disclosed is a field device in which only the faults are displayed that are relevant for the respective user application. Said field device comprises an apparatus (25) for recognizing a plurality of field device-specific faults and generating associated field device-specific fault messages, a memory (29) for storing an application-specific fault message profile containing exclusively the field device-specific faults that are relevant for a specific application, an interface (31) via which a user predefines the fault message profile and files the same in the memory (29), and an apparatus (31) for outputting fault messages. Said apparatus (31) outputs exclusively the fault messages of the faults contained in the fault message profile.

    摘要： The invention relates to a method for determining and monitoring the level (2) of a medium (3) in a container (9) with a level-measuring device (1), in which high-frequency measurement signals (HF) are guided by the method of time-domain reflectometry to the medium (3) via at least one measurement probe (5) and are reflected and received at at least one boundary layer (4) of the medium (3) as useful echo signals (N) or at interference points (14) as interference echo signals (S), wherein a current echo curve (E1) is derived from a generated reference echo signal (R) together with the useful echo signals (N) and the interference echo signals (S). A reference point (B) in the current echo curve (E1) is thereby localized at least from a first interference echo signal (S1) and the reference echo signal (R) that are produced in a measurement-inactive region (12) of the level measurement device (1), and the level (2) is determined from the distance (D) from the useful echo signal (N) constructed in a measurement-active region (11) of the level-measuring device (1) to the reference point (B).

    摘要： The invention relates to a method for checking the proper functioning of a level indicator (1), which works according to the propagation time principle. For this method, a reading curve at an actual filling level (hactual) is determined at defined or selectable intervals (ta) and the useful echo signal is determined using the actual reading curve. The actual useful echo signal is used to determine an expected value (E) for the quality of the useful echo signal at at least one defined level (hdesired). The determined expected value (E) for the quality of the useful echo signal is compared at the defined filling level (hdesired) with a defined critical value for the quality, and a faulty state is diagnosed if the determined expected value falls below the critical value for the quality.

    摘要： A method for monitoring the functioning of a field device, wherein the field device provides a complex measurement signal, which is produced from a number of individual measurements following one another in time, comprising method steps as follows: the complex measurement signals are stored within a predetermined time window; the occurrence of a predetermined event is monitored in the field device; the stored complex measurement signals are overwritten for the case, in which the predetermined event does not occur within the predetermined time window; for the case, in which the predetermined event occurs within the predetermined time window, both a first defined number of complex measurement signals, which were ascertained in time directly before the occurrence of the event, are frozen, as well as a second defined number of complex measurement signals, which were ascertained in time directly after the occurrence of the predetermined event, are stored.

    摘要： The invention relates to an electronic device (1) with electronics (9) comprising electronic and/or electromechanical components (11) arranged in an electronic chamber (7), the device being able to automatically detect and/or monitor wear of its electronic and/or electromechanical components (11), comprising a device (15) for the detection and/or monitoring of wear of the electronic and/or electromechanical components (11), the device having at least one part (17, 17a, 17b) that is arranged in the electronic chamber (7) and is independent from the electronics (9), wherein the part has at least one physical property that changes irreversibly as a function of the wear of the part (17, 17a, 17b). A circuit (31) for measuring said physical property is provided. The invention further comprises an evaluation unit (33), which detects and/or monitors wear of the part (17, 17a, 17b) based on the measured physical property and providing an output signal (S) that is dependent on the wear.
