Abstract

Dans ce système de mesure qui permet de détecter la position d'un piston (6) mobile dans un cylindre (1) susceptible de recevoir une pression, un transmetteur de position (11), par exemple sous forme d'un aimant, est relié au piston (6) à l'intérieur du cylindre, et un capteur (12) susceptible d'être entraîné le long du trajet de déplacement du transmetteur de position (11) par un mécanisme d'entraînement (13, 14) est monté à l'extérieur du cylindre (1) et détecte l'intensité des signaux générés par le transmetteur de position (11) proportionnellement à son éloignement du transmetteur de position (11). Un régulateur (17) permet de commander le capteur (12) de sorte qu'il présente des signaux d'une intensité maximale. En détectant la position du capteur (12), on peut en conclure la position du transmetteur de position (11).
