Abstract
La détection du seuil d'usure est opérée, pour chacun des balais 3, à l'aide d'un système de fibre optique 5 associé à un émetteur 6 et à un récepteur 7, afin d'occulter automatiquement le flux lumineux lorsque l'usure atteint la partie extrême de la fibre qui est noyée dans le balai. Plusieurs formes de réalisation du système 5 sont décrites en détail. (CF DESSIN DANS BOPI)The wear threshold is detected, for each of the brushes 3, using an optical fiber system 5 associated with an emitter 6 and a receiver 7, in order to automatically conceal the light flux when the wear reaches the extreme part of the fiber which is embedded in the brush. Several embodiments of the system 5 are described in detail. (CF DRAWING IN BOPI)
