Abstract
Es wird ein Sensor zur Bestimmung der Dielektrizitätskonstanten eines Kraftstoffs vorgeschlagen, der dazu dient, unterschiedliche Kraftstoffarten durch die Bestimmung ihrer unterschiedlichen Dielektrizitätskonstanten zu unterscheiden. Hierzu wird erfindungsgemäss eine kapazitive Messanordnung vorgeschlagen, welche eine Kondensatoranordnung mit konzentrischen Kondensatorelektroden aufweist.
