FIELD: physics; measurement.
SUBSTANCE: invention relates to weight measurement techniques and is meant for dynamic calibration of belt-conveyer weighers. The device has an imitation mechanism, comprising a flexible belt loaded with calibration loads, and weights put on the conveyer belt at the measuring section and attached by one end to the flight of the conveyer. The device is installed with possibility of measuring the length of the belt and revolution time of a section of the conveyer of a given length. Ball bearings with free-rolling captive balls are uniformly fitted on the entire surface of the flexible belt.
EFFECT: more accurate calibration.
