Abstract

L’invention porte sur un dispositif de mesure (10) d'une quantité de matériau superparamagnétique, le dispositif comprenant une paire de bobines de mesure (P1) et une paire de bobines de compensation (P2), les bobines d’une paire (P1, P2) étant identiques entre elles et disposées, dans le dispositif, symétriquement par rapport à un plan de référence. Le dispositif comprend également au moins un générateur d'un courant continu (GDC), un générateur basse fréquence (GBF), et un générateur haute fréquence (GHF), les générateurs (GDC, GBF, GHF) étant couplés aux première et deuxième paires (P1, P2) pour injecter dans chacune des bobines (P1A, P1B, P2A, P2B) un courant ayant une composante continue, une composante haute fréquence et basse fréquence de telle sorte que les champs magnétiques générés par les bobines d’une même paire soient identiques. Le dispositif comprend également détecteur d'une composante d’une tension électrique établie à une fréquence de mélange combinaison linéaire de la première et de la deuxième fréquence.
