摘要： A scintillation detector, especially one for a radiometric measuring device for measuring and/or monitoring a measured variable, especially a fill level of a fill substance located in a container, for covering a predeterminable measuring range as flexibly as possible in shape and length. To this end, the scintillation detector comprises two or more scintillators arranged in series relative to one another for converting thereon falling, radioactive radiation into light flashes, whose light propagates in the respective scintillator toward its ends. Arranged between the scintillators are optical coupling elements, which establish light transmitting connections between adjoining pairs of scintillators. Connected at an end of the series is a photoelectric transducer, which converts light occurring in the series into an electrical signal corresponding to a radiation intensity striking the scintillators. According to the invention, at least one of the coupling elements is a mechanically flexible element, which includes a bundle of light conducting fibers, via which transmission of the light between the two scintillators connected with one another via the fibers occurs.

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.
