Abstract

Vorrichtung zum Prüfen von Münzen mit einer induktiven Sensoranordnung, die eine Sende- und eine Empfangsspule aufweist, deren Feld von einer Münze durchquert wird, bei der die Sendespule von einem Sendesignal gespeist wird und ein Ausgangssignal der Empfangsspule in eine Auswertevorrichtung gegeben wird, welche das Ausgangssignal auswertet, zur Erzeugung eines Annahme- oder Rückgabesignals, wobei Sende- und Empfangsspule auf einem Ferritkem auf einer Seite der Münzlaufbahn angeordnet sind und der Durchmesser der Sendespule so groß ist, daß ihr Feld in der Mitte einen homogenen Verlauf zeigt und die Empfangsspule im homogenen Feldbereich der Sendespule angeordnet ist.
