ベルトコンベア測長器。 A length detector that includes a roller to be brought into contact with the belt of a belt conveyor and outputs a pulse every time it rotates a predetermined amount of rotation, and a position detector that detects a predetermined position in the longitudinal direction of the belt and outputs a position signal. and a belt conveyor length measuring device that measures the belt length based on the pulse of the length detector and the position signal of the position detector, wherein the length detector is determined as a reference value of the belt length. a counting means for counting pulses output while measuring the reference length;
Calculating means that calculates a ratio between the counted value and a predetermined reference pulse number corresponding to the reference length, corrects the counted value of pulses during one rotation of the belt using the ratio, and calculates the belt length. A belt conveyor length measuring device characterized by having.
