SYSTEM FOR MEASURING THE THICKNESS OF A LAYER OF RUBBER FOR A TYRE

摘要

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.
