Abstract

Eine Messvorrichtung verfügt über eine Steuerungseinrichtung, einen Messsignalsender, einen Messsignalempfänger und eine Messspitze. Die Messspitze beinhaltet zumindest eine Koaxialleitung. Die Steuerungseinrichtung steuert den Messsignalsender derart, dass er ein Messsignal mittels der Koaxialleitung in einen bestimmten Ort eines Gewebes sendet. Das Messsignal wird von dem Gewebe gestreut. Die Steuerungseinrichtung steuert den Messsignalempfänger derart, dass er das gestreute Messsignal empfängt. Die Steuerungseinrichtung wertet das empfangene Messsignal aus. Die Messspitze ist derart ausgebildet, dass mit ihr eine Gewebeprobe an dem bestimmten Ort des Gewebes entnehmbar ist. In einem alternativen Ausführungsbeispiel beinhaltet die Messspitze zumindest zwei Koaxialleitungen und eine Resonatorschaltung. Eine alternative Messspitze beinhaltet abgeschrägt ausgeführte Koaxialleitung (58, 59).
