Disclosed is an apparatus for determining an amount of poured material on a belt conveyor. Said apparatus comprises a measuring instrument for the contactless detection of the surface shape of the poured material in a triangulation process, said surface shape being in relation to a cross-sectional plane. The measuring instrument encompasses a bending-resistant and torsion-resistant support (1) for accommodating light transmitters (3) and detectors (4) that are associated with the light transmitters (3) and are equipped with a light collector (11) for the light beams reflected by the poured material. In order to create advantageous structural conditions, the light collectors (4) are inserted into concentric through-holes (5) of the support (1), and said through-holes (5) form an inward-projecting supporting shoulder (6) for the respective light collector (11) which is maintained on the supporting shoulder (6) in a pressed manner such that an intermediate annular seal (7) is elastically deformed. |
