Abstract

Un trasduttore per la misurazione di massa comprende due sistemi meccanicamente indipendenti, un sistema di carico nel quale una forza prodotta su una bobina di carico da una corrente elettrica, passante nella bobina medesima, compensa l'effetto di una massa collocata sulla piastra di pesatura, ed un sistema di riferimento, nel quale una forza prodotta su una bobina di riferimento compensa l'effetto di una massa costante di riferimento. Entrambe le bobine sono situate entro il cam-po di un comune gruppo magnetico, e la connessione tra la piastra di pesatura e la bobina di carico è realizzata da una doppia leva piegata. La massa è determinata dal rapporto delle correnti nella bobina di carico ed in quella di riferimento.fig. 2A transducer for mass measurement comprises two mechanically independent systems, a load system in which a force produced on a load coil by an electric current passing through the coil itself compensates for the effect of a mass placed on the weighing plate, and a reference system, in which a force produced on a reference coil compensates for the effect of a constant reference mass. Both coils are located within the field of a common magnetic assembly, and the connection between the weighing plate and the loading coil is made by a double folded lever. The mass is determined by the ratio of the currents in the load coil and in the reference coil. 2
