A sensor system for measuring the level of a fluid (6) includes a tube (2) having a primary coil (10) and a pair of secondary coils (12, 14) wound thereabout. The secondary coils have a periodically varying winding density distribution. The winding density distribution of one secondary coil is shifted relative to the winding density distribution to the other secondary coil. A float (4') positioned adjacent the tube modifies an electromagnetic field produced by the primary coil. In response to the modified electromagnetic field, the first and secondary coils produce first and second signals having amplitudes that vary periodically in response to the movement of the float between the ends of the tube.

L'invention porte sur un système de capteur conçu pour mesurer le niveau d'un fluide et comportant un tube autour duquel un enroulement primaire et une paire d'enroulements secondaires sont bobinés. Les enroulements secondaires présentent une répartition de densité variable de manière périodique. La répartition de la densité de l'un des enroulements secondaires est décalée par rapport à celle de l'autre enroulement secondaire. Un flotteur voisin du tube modifie le champ électromagnétique produit par l'enroulement primaire. En réponse aux variations du champ électromagnétique, les enroulements primaires et secondaires produisent un premier et deuxième signal dont l'amplitude varie périodiquement selon les mouvements du flotteur entre les extrémités du tube.
