Abstract
The determination and differentiation of various materials is of great interest in numerous applications. For this purpose, spectroscopic impedance measurement systems are applied. The frequency dependent impedance analysis enables a detailed material investigation and an assessment of its composition e. g. the moisture content. By applying impedance measurement systems in industrial environments conditions as high temperatures, high pressures or vibrations have to be considered. In this paper we present a front-end topology intended to be used for frequency spectroscopic based measurement systems, deployed in industrial environments. The impedance measurement capability of the proposed system is investigated by means of a realized prototype. We present results obtained for measurement frequencies up to
Zusammenfassung
Die Bestimmung und Unterscheidung verschiedener Materialien ist in zahlreichen Anwendungen von großem Interesse. Zu diesem Zweck werden spektroskopische Impedanz-Messsysteme verwendet. Die frequenzabhängige Impedanzanalyse ermöglicht eine detaillierte Materialuntersuchung und eine Beurteilung ihrer Zusammensetzung, z. B. des Feuchtegehalts. Die Information über den Feuchtegehalt von verarbeiteten Materialien ist von großem Interesse in industriellen Anwendungen, und dient der Prozessoptimierung. Bei der Anwendung von Impedanz-Messsystemen in industriellen Umgebungen muss das Auftreten von hohen Temperaturen, hohen Drücken oder Vibrationen berücksichtigt werden, welche im industriellen Umfeld üblich sind. In diesem Artikel stellen wir ein Frontend vor, dass für frequenzspektroskopisch basierte Messsysteme im industriellen Umfeld verwendet werden soll. Ein realisierter Prototyp wird auf seine Fähigkeit Impedanzen zu bestimmen untersucht. Wir präsentieren Messergebnisse für Frequenzen bis zu
