Abstract

Die Erfindung betrifft ein Verfahren zur Messung von Abständen im Bereich des Stoffauflaufes einer Papiermaschine. Sie ist vornehmlich dadurch gekennzeichnet, daß magnetische Gleichfelder im Bereich des Stoffauflaufspaltes erzeugt werden, deren Stärke gemessen und daraus der Abstand der einzelnen Lippen bestimmt wird. Die Erfindung betrifft auch eine Meßeinrichtung zur Bestimmung von Abständen im Bereich des Stoffauflaufs 1 einer Papiermaschine bei der im einen der beiden, den Abstand bestimmenden Elemente 11 ein Magnetfelderzeuger 10 für ein magnetisches Gleichfeld und am zweiten der beiden, den Abstand bestimmenden Elemente 7, 8 ein Magnetfeldmeßgerät 9 vorgesehen ist.
