Radiometric fill level measurement

Abstract

A constructively simplified detector for a radiometric measuring system, wherein the measuring system serves for determining density or fill level of a fill substance in a container, includes: a scintillator; a photomultiplier, which is optically connected with the scintillator such that it generates an electrical evaluation signal as a function of radioactive radiation intensity entering the scintillator; and an evaluation unit of the detector connected to the photomultiplier, which determines density or fill level of the fill substance based on the evaluation signal. The detector is distinguished by an optically and magnetically shielding housing, which shields at least the scintillator and the photomultiplier. As a result, a separate, magnetic shielding of the photomultiplier is unnecessary. In this way, the number of components and, thus, effort to produce the detector are reduced.
