Abstract

L'invention concerne un système de mesure de niveau basé sur une colonne de capteurs à effet Hall avec étalonnage automatique, relevant du domaine technique des équipements dans lesquels la mesure de niveau de manière linéaire est requise, consistant en un système de mesure de niveau pour doseurs de produit chimique, basé sur une colonne de capteurs à effet Hall, avec étalonnage automatique en temps réel des capteurs, pendant la mesure. Cet étalonnage automatique résout le problème de l'imprécision de mesure causée par la variation du gain et du décalage des capteurs Hall en fonction de la variation de température, et résout également le problème de l'erreur causée par la variation du champ magnétique de l'aimant en fonction de la démagnétisation, de la température ou du vieillissement.
