Abstract

Metodo per la traduzione e la rilevazione di posizione in cui il campo magnetico da rilevare viene generato per induzione magnetica nello spazio circostante ad un reoforo planare percorso da corrente elettrica (SP1, SP2), e la grandezza da misurare; direttamente o attraverso un opportuno trasduttore, è ricondotta a un movimento relativo tra un sensore di campo magnetico (D1, D2) e detto reoforo che lo genera. L'intensità del campo magnetico è legata alla forma del reoforo in un punto, in particolare alla sua larghezza? Se realizzato con film metallico. La variazione della forma del film può essere fissata con una legge che tiene conto del tipo di variazione della grandezza da misurare. (Fig. 8).
