Abstract

Un dispositivo di rilevamento della velocità di rotazione tra due organi in rotazione relativa quali gli anelli di un cuscinetto della ruota di un veicolo, del tipo comprendente una ruota fonica solidale all'anello rotante del cuscinetto ed un sensore passivo o bobina di rilevamento portato dall'anello fisso del cuscinetto. Il sensore è costituito da un avvolgimento a basso numero di spire collegato ad un traslatore o trasformatore elevatore della tensione.
