A testing system for conveyor belts where there is a plurality of testing sections positioned at various locations along the length of the belt to ascertain condition of the belt in these locations. Each test section comprises a radio frequency identification member so that when the test section passes through a monitoring region where there is a monitoring apparatus, the radio frequency identification member transmits an identification signal to indicate the presence of a testing device. The monitoring apparatus transmits an activating signal to the testing device which in turn directs an electric current through a conductive loop extending transversely across the belt. If there is a fault in the belt which severs the wire so that current does not flow, this is detected by the monitoring apparatus to indicate a fault.
L'invention concerne un système de test pour des bandes transporteuses, comprenant une pluralité de sections de test situées à différents emplacements sur la longueur ladite bande transporteuse, de façon à déterminer avec précision l'état de la bande à ces emplacements. Chaque section de test comprend un élément d'identification radiofréquence de sorte que lorsque ladite section de test traverse un région de surveillance pourvue d'un appareil de surveillance, l'élément d'identification radiofréquence transmet un signal d'identification qui indique la présence d'un dispositif de test. L'appareil de surveillance transmet un signal d'activation au dispositif de test, qui à son tour dirige un courant électrique à travers une boucle conductrice s'étendant transversalement sur la bande. Si une détérioration de la bande disjoint un fil de sorte que le courant ne s'écoule pas, elle est détectée par l'appareil de surveillance.
