Abstract

La présente invention concerne l'utilisation d'un câble à forme plate ou ronde dans un capteur à boucle d'induction. Ce capteur peut être installé dans un sillon entaillé dans une route ou positionné dans une nouvelle route. Il comprend une boucle d'induction constituée d'un conducteur, protégé par une gaine, enroulé sur un ou plusieurs tours. Une zone de connexion permet de relier les premières et secondes extrémités du conducteur en boucle à une paire de fils d'un câble d'entrée. La zone de connexion se trouve enfermée de manière étanche dans un connecteur moulé. Cette boucle peut être constituée de câble à forme ronde.
