    • A radiometric measuring arrangement for measuring fill level of a fill substance in a container includes: arranged one above the other in measurement operation on a first side of the container, two or more radiometric radiators, which, in measurement operation, send radioactive radiation through the container, and which, in measurement operation, are arranged in a measuring position in the interior of the container in a pressure resistant, protective tube protruding laterally into the container; and, arranged on a second side of the container lying opposite to the radiators, at least one detector, which serves to receive radiation intensity penetrating through the container as a function of fill level and to convert such into a fill level dependent, electrical signal. The measuring arrangement permits achievement of a highly linear dependence of total detected radiation intensity on fill level. At least in protective tubes, above which at least one further radiator is located, above the radiator of such a protective tube, an absorber is arranged, which serves to absorb radiometric radiation upwardly radiated by the radiator of such protective tube, when such radiator is located in the measuring position.
    • 一种用于测量容器中的填充物质的填充水平的辐射测量装置,包括:在容器的第一侧的测量操作中彼此重叠的两个或更多个放射性辐射器,其在测量操作中通过 容器,并且在测量操作中,在横向放置在容器中的耐压保护管中,在容器内部的测量位置中布置; 并且布置在与散热器相对的容器的第二侧上,至少一个检测器,其用于接收穿过容器的辐射强度作为填充水平的函数,并将其转换为依赖于填充水平的电信号。 测量装置允许实现总检测的辐射强度对填充水平的高度线性依赖性。 至少在保护管中,至少有一个另外的散热器位于这种保护管的散热器的上方,设置有吸收器,用于吸收由这种保护管的散热器向上辐射的辐射辐射,当这种散热器是 位于测量位置。
