Abstract

Balance à système de charge et à système de référence compensés électromagnétiquement. Le chiffrage des signaux du trajet de charge 25 et du trajet de référence 26 s'effectue simultanément, le début et la fin de l'opération coïncidant pour les deux genres de signaux. Application notamment aux balances à formation de quotient.
