Abstract

Die Erfindung betrifft eine Vorrichtung (10) zur berührungslosen Erfassung einer Drehung oder Drehzahl eines Messobjekts (12), mit einem Sensor (14), der zur berührungslosen Drehungs- oder Drehzahlerfassung des Messobjekts (12) dient. Erfindungsgemäß ist vorgesehen, dass der Sensor (14) ein Ultraschallsensor (14) ist. Weiterhin betrifft die Erfindung ein Verfahren zur berührungslosen Erfassung einer Drehung oder Drehzahl eines Messobjekts (12). Erfindungsgemäß ist vorgesehen, dass es ein berührungsloses Erfassen einer Drehung oder Drehzahl des Messobjekts (12) auf der Grundlage von Ultraschall umfasst. Darüber hinaus bezieht sich die Erfindung auf eine Verwendung eines Ultraschallsensors (14). Erfindungsgemäß ist vorgesehen, dass der Ultraschallsensor zur berührungslosen Drehungs- oder Drehzahlerfassung eines Messobjekts (12) verwendet wird.
