Abstract

Es werden ein Verfahren und eine Vorrichtung zum Bestimmen der Dichte eines Zigarettenstrangs beschrieben. Zur Dichtebestimmung wird die Intensität der Strahlung (8) einer Röntgenstrahlungsquelle (7) erfaßt, nachdem sie den Strang (1) durchdrungen hat. Die Röntgenstrahlung (8) wird mittels Röntgenstrahlungsdetektoren (14) erfaßt, die als Linienarray (13) angeordnet sind. Dieses Linienarray (13) weist einen zusätzlichen Röntgenstrahlungsdetektor (14.2) auf, der die Intensität eines den Strang nicht durchdringenden Teils der Röntgenstrahlung (8) als Referenzstrahlung separat erfaßt und ein entsprechendes Referenzsignal erzeugt. Außerdem ist ein weiterer Röntgenstrahlungsdetektor (14.1) vorgesehen, der gegen die Röntgenstrahlung dauernd abgeblendet ist und ein Dunkelsignal abgibt. Die Meßsignale (S3 bis Sn) , das Referenzsignal (S2) und das Dunkelsignal (S1) werden an eine Auswertanordnung (16) übergeben, die diese Signale zu einem Dichtesignal (17) verarbeitet.
Diese Art der Dichtemessung verhindert das Meßergebnis verfälschende Einflüsse von Driften und Alterungsvorgängen der Röntgenstrahlungsquelle- und detektoren auf das Meßergebnis.
