摘要： 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. For this, 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 the Geiger mode, which convert light impinging thereon into an electrical signal, wherein at least one end of each scintillation fiber is connected to avalanche photodiodes of one of the arrays. 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.

摘要： 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. In an interval successive radiation intensities are measured, a distribution of the radiation intensities, two separated Poisson distributions are identified within the distribution, based on the positions of the Poisson distributions identified within the distribution, an upper threshold value is determined for the radiation intensity, the exceeding of which upper threshold value by a radiation intensity measured following the interval means a state change into the state, free of medium, has been detected, and/or a lower threshold value is determined for the radiation intensity, the subceeding of which lower threshold value by a radiation intensity measured following the interval means a state change into the state, covered by medium, has been detected.
