Abstract

Die Erfindung bezieht sich auf einen Ultraschall-Sensor für eine Dunstabzugshaube, wobei der Sensor den vom Kochgut zur Dunstabzugshaube aufsteigenden Wrasen überwacht. Es erfolgt ein automatischer Abgleich der Temperatur- und Alterungsdrift des Sensors. Zu diesem Zwecke wird zyklisch während des laufenden Betriebs des Sensors eine Überprüfung der Resonanzfrequenz vorgenommen, wobei deren Verschiebung erkannt, durch ein statistisches Berechnungsverfahren die neue Resonanzfrequenz festgestellt und für den weiteren Betrieb des Sensors verwendet wird.
