Abstract

Vorbeschrieben ist ein Verfahren mit zugehöriger Schaltungsanordnung, bei denen zur Auswertung eines Messsignals, das auf gegenüber Nullpotential höherem Potential in einer Messeinrichtung, die einen Versorgungsstrom benötigt, als Analogwert anfällt und dessen Messinformation nach einer A/D-Wandlung als Digitalsignal zu einer auf Erdpotential liegenden Auswerteeinheit übertragen wird. Dabei liefert das erzeugte Digitalsignal den Takt für eine Modulation des Versorgungsstromes und erfüllt somit gleichermaßen die Funktion des Trägers für den Informationsgehalt des Messsignals. Gemäß der Erfindung werden gekrümmte Kennlinien zur Kompression/Dekompression der Signale verwendet. Gleichermaßen sind geeignete Mittel zur Temperaturkompensation vorhanden.
