Abstract
BALANCE COMPRENANT UN LEVIER QUI DETERMINE LE RAPPORT DE TRANSMISSIONS ET QUI EST PLACE ENTRE LE SUPPORT DE LA CHARGE ET LE MONTAGE DE COMPENSATION (BOBINE DANS LAQUELLE CIRCULE UN COURANT ET QUI EST PLACEE DANS L'ENTREFER D'UN AIMANT PERMANENT). LA BOBINE DE COMPENSATION 28 COMPORTE UNE PRISE ET UN COMMUTATEUR 42 DIRIGE LE COURANT DE COMPENSATION EN ALTERNANCE SUR L'UNE ET SUR L'AUTRE PARTIE DE CETTE BOBINE. APPLICATION AUX BALANCES DE CE MODELE DE MANIERE A PERMETTRE D'UTILISER LE MEME LEVIER 18 POUR PLUSIEURS TYPES DE BALANCES D'UNE MEME FAMILLE SANS AVOIR A MONTER SUR CE LEVIER DES POIDS AUXILIAIRES D'EQUILIBRAGE.
