Abstract
A device for counting the rotations of a tire on a vehicle using the deformations that the tire undergoes on each rotation of the wheel, comprising a casing, a sensor intended to generate an electrical signal on each rotation of the wheel, and connection means intended to mechanically connect the casing and the sensor to the surface of the tire. The sensor is in the form of a passive sensor in one piece with the casing, whereof the signals emitted are in proportion with the variations over time in a magnetic flux through the said passive sensor, and a magnetic field generator is arranged opposite the passive sensor. The connection means mechanically connect the casing to a first surface A and the magnetic field generator to a second surface B, the two surfaces A and B being substantially coplanar and offset from one another in a direction D by a given distance L. The electrical signal is produced by the relative displacements of the said passive sensor and the said magnetic field generator.

12. A device for counting the rotations of a tire on a vehicle using the deformations that the tire undergoes on each rotation of the wheel, comprising
a casing, a sensor intended to generate an electrical signal on each rotation of the wheel, and connection means intended to mechanically connect the casing and the sensor to the surface of the tire, wherein the sensor is in the form of a magnetic field generator, and a sensor sensitive to the magnetic field and in one piece with the casing, arranged opposite the magnetic field generator, wherein said connection means mechanically connect the casing to a first surface A and the magnetic field generator to a second surface B, the two surfaces A and B being substantially coplanar and offset from one another in a direction D by a given distance L, and wherein said electrical signal is produced by the relative displacements of said magnetic field generator and the said sensor sensitive to the magnetic field.
