Abstract

Le capteur que nous proposons est un capteur électromagnétique de forces, il est constitué de deux bobines plates reliées entre elles par un ressort, une bobine fixe est alimentée par un oscillateur de wien dont les conditions de phases et d'amplification sont satisfaites; par induction magnétique, il se crée une force électromotrice dans l'autre bobine mobile. Cette tension varie en fonction de la distance inter bobines. Le principe de fonctionnement du capteur proposé repose donc sur les lois fondamentales de l'électromagnétisme. Le ressort joue le rôle d'un convertisseur force déplacement.
