Abstract

Die Erfindung betrifft eine Streufeldsonde zum Messen von dielektrischen Eigenschaften von Stoffen, mit Erzeugungsmitteln zur Erzeugung eines elektrischen Feldes, mit Abschirmmitteln zum Abschirmen des erzeugten elektrischen Feldes, wobei die Abschirmmittel derart ausgebildet sind, daß sich das elektrische Feld zumindest teilweise außerhalb der Abschirmmittel befindet. Die Erfindung zeichnet sich dadurch aus, daß die Abschirmmittel zur Auskopplung des elektrischen Feldes in den Außenraum mindestens zwei Öffnungen aufweisen.
