Abstract

Jauge pour détecter ou mesurer une dimension de la section transversale ou un écart par rapport à une forme ou à une dimension de section transversale prédéterminée d'un objet allongé. Elle comprend un carter tubulaire rotatif 10 dont l'axe de rotation longitudinal coïncide avec le trajet de déplacement prévu de l'objet à jauger. Le carter de la jauge porte une source lumineuse 2 qui dirige un faisceau de lumière à rayons parallèles sur l'objet 4 au cours du passage de ce dernier dans le carter. Des réseaux 8, 9 de photodiodes montés sur le carter en un emplacement diamétralement opposé à la source lumineuse reçoivent les images des limites de l'objet en déplacement et produisent des signaux électriques à partir desquels les paramètres à détecter ou à mesurer peuvent être calculés. Application au contrôle de barres, tiges ou billettes sortant d'un laminoir.
