ERROR REDUCTION FOR NUCLEAR BELT WEIGHERS

Abstract

Nuclear belt weighers have the advantage of contactless measuring bulk goods transported by conveyor belts while electromechanic belt weighers suffer from mechanical interferences. Up to now the profile error restricted the applicability of nuclear belt weighers to fine grained material. In the paper the nuclear belt weigher and the profile error are analysed. A new scanning algorithm, implemented on a 8085-microprocessor system resolves the problem of profile error, improves precision and resolution in comparison to electromechanic belt weighers and generates an applicability of nuclear belt weighers in new fields.
