Abstract
Die Erfindung betrifft ein Verfahren zur Messung physikalischer Eigenschaften von Endlospressgütern, bei dem in das Pressgut Sensorelemente und damit verbundene Koppelelemente eingebettet werden und bei dem weiterhin eine Abfrageeinrichtung vorgesehen ist, welche zu den Koppelementen eine elektrische Wirkverbindung aufweist und bei dem die Sensorelemente angeregt werden, und aus dem Antwortsignal (TX) eine Aussage über die physikalischen Eigenschaften der Endlospressgüter getroffen wird, dadurch gekennzeichnet, dass das Antwortsignal (TX) in der Abfrageeinrichtung sowohl an den ersten Eingang (A) eines Multiplikatorelementes (M) als auch über einen frequenzabhängigen Phasenschieber (P) an einen zweiten Eingang (A) des Multiplikatorelementes (M) angelegt wird, dass das Ausgangssignal (C) des Multiplikatorelementes (M) über einen Tiefpass (TP) geführt wird und dass das Ausgangssignal (C) des Tiefpasses (TP) zur Ermittlung der Aussage über die physikalischen Eigenschaften der Endlospressgüter herangezogen wird.
