A field-altering device for an inductive sensor has an elongated body with a substantially saw-tooth profile. The body is made of steel or other type ferrous material. With use in a Hall-effect sensor, the body moves relative to the sensor causing the field to vary periodically with time. The sensor generates an electrical signal in dependence on the field variations, the electrical signal having a saw-tooth pattern.

Un dispositif à modification de champ pour capteur à induction a un corps allongé avec un profil en dent de scie. Le corps est en acier ou en d'autres types de métaux ferreux. Par l'emploi d'un détecteur à effet Hall, le corps bouge par rapport au détecteur provoquant la variation périodique du champ avec le temps. Le détecteur génère un signal électrique dépendant des variations de champ, le signal électrique ayant un profil en dent de scie.
