Abstract

Dispositif de mesures capacitives d’une hauteur d’un fluide dans un réservoir, comportant au moins un couple de condensateurs (Ci L, Ci R), s’étendant suivant une direction longitudinale (Z’-Z), et comportant : - un premier condensateur (Ci L), formant des premiers motifs géométriques (Ci LB, Ci LT) définissant une première capacité électrique linéique ; - un second condensateur (Ci R), opposé au premier condensateur (Ci L), et formant des seconds motifs géométriques (Ci R B, Ci R T) définissant une seconde capacité électrique linéique ; les premiers et seconds motifs géométriques (Ci LB, Ci LT ; Ci R B, Ci R T) étant agencés de sorte que : - les première et seconde capacités électriques linéiques, intégrées suivant la direction longitudinale (Z’-Z), possèdent une somme qui dépend de la position du fluide suivant la direction longitudinale (Z’-Z) ; - les première et seconde capacités électriques linéiques, intégrées suivant la direction longitudinale (Z’-Z), possèdent une différence qui est une constante pour des positions de référence du fluide suivant la direction longitudinale (Z’-Z).
