Title (EN) SYSTEM FOR MEASURING THE THICKNESS OF A LAYER OF RUBBER FOR A TYRE
(FR) SYSTÈME DE MESURE DE L'ÉPAISSEUR D'UNE COUCHE DE GOMME D'UN PNEUMATIQUE
Abstract:
(EN) The invention concerns a system for measuring the thickness of a layer of rubber material for a tyre, the layer having a face connected to an adjacent metal reinforcement and a free face which is in contact with the air. The system comprises a sensor which can measure the distance d between the connected face and the free face of the rubber material layer, the sensor comprising a single exciting and measuring winding, and the exciting power and frequency of the winding being such that the inductance at the winding terminals increases as the distance d decreases.
(FR) Système de mesure de l'épaisseur d'une couche de matériau caoutchouteux d'un pneumatique, ladite couche comportant une face liée à une armature adjacente métallique et une face libre en contact avec l'air, le système comprenant un capteur capable de mesurer la distance d entre la face liée et la face libre de la couche de matériau caoutchouteux, dans lequel le capteur comporte une unique bobine d'excitation et de mesure, et la fréquence et la puissance d'excitation de la bobine sont telles que l'inductance aux bornes de ladite bobine augmente lorsque la distance d diminue.
