Europäische Patentanmeldung Nr. 83200187.9 Lichtwellenleiter zur Feuchtigkeitsüberwachung und Kabel mit einem derartigen Lichtwellenleiter. PATENTANSPRÜCHE
1. Überwachungsader, gekennzeichnet durch einen feuchtigkeitsdurchlässigen, schlauchartigen Bestandteil, welcher neben einem Lichtwellenleiter ein feuchtigkeitsabhängiges Quelmittel enthält.
2. Uberwachungsader nach Anspruch 1, dadurch gekennzeichnet, dass der schlauchartige Bestandteil (1) eine Druckfläche mit Wellenmuster (3) aufweist, wobei der Lichtwellenleiter (6) durch die Einwirkung der in den schlauchartigen Bestandteil (1) eingedrungenen Feuchtigkeit gegen die Druckfläche gedrückt wird.
3. Uberwachungsader nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass das Quellmittel in oder auf einem Träger angebracht ist.
4. Uberwachungsader nach Anspruch 3, dadurch gekennzeichnet, dass der Träger einen im wesentlichen runden Durchmesser hat.
5. Überwachungsader nach Anspruch 1, 2 oder 3, dadurch gekennzeichnet, dass in dem schlauchartigen Bestandteil eine Membrane (7) als Trennungswand zwischen dem Quellmittel (5) und dem Lichtwellenleiter (6) angebracht ist.
6. Kabel, bestehend aus einem oder mehreren Informationslichtwellenleitern und einer sternförmigen Kabelseele (9), dadurch gekennzeichnet, dass eine oder mehrere der Aussparungen (10) der Kabelseele (9) eine optische Überwachungsader (6) und ein feuchtigkeitsabhängiges Quellmittel (5) enthält.
