Abstract: A measuring arrangement for radiometric density-or fill level measurement of a medium in a measuring tube in the field of automation technology. The measuring arrangement is composed of a radioactive radiation source, a detector unit and a clamping apparatus for the radiation source as well as the detector unit. The invention is distinguished by features including that the clamping apparatus has blocking elements, which make the radiation cone of the radioactive radiation source between the measuring tube and the clamping apparatus laterally inaccessible. In such case, the blocking elements are arranged in such a manner that the measuring arrangement is suitable for different diameters of the measuring tube, without the blocking elements losing their protective action.

Abstract: Radiometric measuring arrangement for measuring and/or monitoring a measured variable, especially a fill level or a density, of a fill substance located in a container and a method executable therewith for detection of accretion formation in the container. The variable to be measured is measured by means of a measuring system, which during operation sends radioactive radiation along a measuring path through the container, and measures radiation intensity emerging from the container along the measuring path, and by means of a comparison measuring system, which sends radioactive radiation along a comparison path through the container and measures radiation intensity emerging from the container along the comparison path.

Abstract: The invention relates to a measuring arrangement (1) for radiometric density- or fill level measurement of a medium in a measuring tube (2) in the field of automation technology. The measuring arrangement (1) is composed of a radioactive radiation source (3), a detector unit (4) and a clamping apparatus for the radiation source (3) as well as the detector unit (4). The invention is distinguished by features including that the clamping apparatus has blocking elements (7,8,9,10), which make the radiation cone (17) of the radioactive radiation source (3) between the measuring tube (2) and the clamping apparatus laterally inaccessible. In such case, the blocking elements (7,8,9,10) are arranged in such a manner that the measuring arrangement (1) is suitable for different diameters of the measuring tube (2), without the blocking elements (7,8,9,10) losing their protective action.

Abstract: An apparatus for determining the fill level of a medium in a container, comprising: an emitting unit to be monitored in the container and emits radioactive radiation into the container; a first detector unit receives radioactive radiation and forwards measurement data relative to the fill level of the medium to a control/evaluation unit; a second detector unit which receives the radioactive radiation, respectively the secondary radiation, wherein two interfaces for transmission of measurement data to the control/evaluation unit are associated with the second detector unit. Via the first interface measurement data are transmitted. Via the second interface measurement data are transmitted. The control/evaluation unit based on measurement data transmitted by the first detector unit and the second detector unit corrects the fill level of the medium in the container in such a manner that the influence of gas or vapor in the gas, or vapor, space on the measured fill level is at least approximately compensated.
