SYSTEM FOR MEASURING THE THICKNESS OF A LINER LAYER OF A TYRE |
摘要 |
A system is provided for measuring a thickness of rubber layer of a tire. The layer includes a joined face, which is joined to an adjacent metal reinforcement, and a free face in contact with air. The system includes a casing with an application face for contacting the free face, and a sensor positioned in the casing and structured to measure a distance d between the joined face and the free face. The sensor includes a source coil and an adjacent sensing element. The source coil is a source of an alternating magnetic field. The sensing element includes a sensing device configured to produce an output signal that is dependent on an induced local magnetic field. An excitation power and a frequency of the source coil are such that the local magnetic field induced between the reinforcement and the source coil increases in strength as the distance d decreases. |
