Abstract
A system for measuring a thickness of a layer of rubber material of a tire includes a sensor. The layer includes a joined face, which is joined to an adjacent metal reinforcement, and a free face, which is in contact with air. The sensor, which measures a distance d between the joined face and the free face, includes a source of a static magnetic field and a sensitive element whose output signal is a function of a level of a local magnetic field. The sensor is positioned in such a way that a magnetic field strength measured by the sensitive element varies when the distance d decreases.
