Abstract

DETECTEUR DE DEPLACEMENT A MOUVEMENT RECTILIGNE, COMPORTANT UNE ELECTRODE MOBILE INTERPOSEE ENTRE DEUX ELECTRODES FIXES AUXQUELLES ELLE EST PARALLELE, FORMANT AINSI DEUX CONDENSATEURS VARIABLES. L'ELECTRODE MOBILE (EV) SE DEPLACE SUIVANT UNE DIRECTION (X-X) INCLINEE PAR RAPPORT AUX ELECTRODES FIXES (EF1, EF2) EN DEMEURANT PARALLELE A CELLES-CI, DE SORTE QUE LES CAPACITES DES CONDENSATEURS SUBISSENT L'UNE UNE HAUSSE ET L'AUTRE UNE BAISSE. LES CONDENSATEURS SONT COUPLES A DES OSCILLATEURS ET L'ON ETABLIT LA DIFFERENCE ENTRE LES FREQUENCES D'OSCILLATEURS OU UN SIGNAL ANALOGUE QUI SERT A LA MESURE DE DEPLACEMENT. L'INVENTION PERMET D'ELARGIR L'INTERVALLE DE MESURE DE DEPLACEMENT.
