  • Patent number: 9158007
    Abstract: 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.

  • Patent number: 8878136
    Abstract: A radiometric measuring device comprising: a radioactive radiator which sends radioactive radiation through a container; and a detector serving to receive a radiation intensity penetrating through the container, dependent on the physical, measured variable, and to convert such into an electrical output signal. The detector includes a carrier, on which at least one scintillation fiber is wound, which converts radiometric radiation impinging thereon into light flashes, whose light propagates in the respective scintillation fiber toward its ends. The detector further includes at least one array of avalanche photodiodes operated in a Geiger mode, which convert light impinging thereon into an electrical signal. The detector also has a measuring device electronics connected to the avalanche photodiodes for producing the electrical output signal, based on the electrical signals of the avalanche photodiodes.

  • Publication number: 20130204550
    Abstract: A method for limit level monitoring with a radiometric limit switch. A detector measures discrete radiation intensities. Statistical distributions of radiation intensities in a state, free of medium, and in a state, covered by medium, are given by two Poisson distributions.

  • Patent number: 8487262
    Abstract: A radiometric for measuring a physical, measured variable of a fill substance located in a container and for outputting a measurement signal, which corresponds to a measured value of the physical, measured variable. The measuring device has available a single line-pair, via which energy supply of the total measuring device occurs, and via which transmission of the measurement signal occurs.

  • Publication number: 20120043466
    Abstract: A radiometric measuring device for measuring a physical, measured variable, especially a fill level or a density, of a fill substance located in a container, and/or for monitoring an exceeding or subceeding of a predetermined limit value for the physical, measured variable, comprising: a radioactive radiator, which, during operation, sends radioactive radiation through the container; and a detector arranged on a side of the container lying opposite the radiator and serving to receive a radiation intensity penetrating through the container, dependent on the physical, measured variable, and to convert such into an electrical output signal. With this measuring device, in an extremely flexibly predeterminable region to be metrologically registered by the detector, a very exact measuring of the radiation intensity can be put into practice.

  • Patent number: 6879425
    Abstract: The invention relates to a device for determining and/or monitoring the density and/or the level (L) of a filling material in a container. A transmitting unit which emits radioactive radiation and a receiving unit which is arranged in such a way that it receives the radioactive radiation or the secondary radiation that is produced by the interaction of the radioactive radiation with the filling material are provided. A regulating/evaluating unit which determines the density and/or the level of the filling material in the container using the measuring data that is supplied by the receiving unit is also provided. The aim of the invention is to provide a device which enables the level or the density of a filling material in a container to be measured reliably. To this end, the receiving unit consists of individual detector units.
