Abstract

Viene proposto un indicatore di corsa (10), il cui corpo mobile (11) presenta uno strato di materiale ferromagnetico e su questo uno strato di materiale di buona conduzione elettrica ma non ferromagnetico. Il corpo mobile (1) penetra in una bobina di misurazione (15) percorsa da una corrente alternata. In seguito all'interazione del campo magnetico della bobina (15) percorsa da una corrente alternata e i due materiali del corpo mobile (11) è possibile compensare l'influenza della temperatura, in modo che le curve di misurazione, con differenti temperature, sull'intero intervallo di misurazione hanno un andamento approssimativamente parallelo.
