Abstract

Détecteur permettant de mesurer une position à petit angle ou petit déplacement d'un rhéomètre rotatif, comprenant de multiples condensateurs indépendants symétriques les uns aux autres. Le dispositif présente à sa sortie un signal différentiel à configuration classique par un pont, qui peut être interprété et mesuré à l'aide de moyens de démodulation électronique classiques. Le dispositif comprend un réseau d'excitation (110), un réseau de mesure (130) et un réseau actif de rotor (120). Le réseau actif de rotor (120) est couplé à un arbre d'entraînement du rhéomètre rotatif et est mesuré par rapport aux réseaux de mesure et d'excitation. Le réseau actif de rotor (120) est commandé par un signal électrique à adaptation précise aux signaux détectés par le réseau de mesure (130). En commandant le réseau actif à l'aide de signaux détectés par le réseau de mesure (130), le détecteur permet une sensibilité réduite à des signaux indésirables qui ne sont pas orientés dans la direction de mesure.
