Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zur Erfassung der Drehzahl eines rotierbaren Teils, die ein mit dem rotierbaren Teil koppelbares drehbewegliches magnetisches Polrad mit über den Umfang alternierend angeordneten magnetischen Nordpolen und Südpolen, und Sensormittel umfasst, die ein magnetfeldempfindliches Sensorelement aufweisen, das das von dem Polrad erzeugte Magnetfeld erfasst. Es wird vorgeschlagen, dass die Sensormittel zwei in einem Abstand angeordnete magnetfeldempfindliche Sensorelemente und einen ferromagnetischen Flussleiter aufweisen.
