Abstract

Beschrieben wird eine Abstandsmeßvorrichtung, die unter Heranziehung einer Koppelsonde, welche ein Sendesignal in eine Leitungsstruktur beispielsweise in einen von einer Kolbenstange, Kolben und Zylinderwand eingegrenzten Hohlleiter einspeist, den Abstand zum Kolben sowohl diskret als auch kontinuierlich mißt.
