Description

Die Erfindung betrifft ein Banddicken-Meßgerät zur fortlauf-enden Messung, Anzeige oder Registrierung der Dicke bandförmiger Materialien. The invention relates to a strip thickness measuring device for continuous ends Measurement, display or registration of the thickness of strip-shaped materials.

Zu diesem Zweck sind beispielsweise Dickenmeßeinrichtungen unter Verwendung von elektrischen Induktionsmeßlehren bekanntgeworden. For this purpose, for example, thickness gauges are below The use of electrical induction gauges has become known.

Werden mit derartigen Einrichtungen Bänder gemessen, die auf höheren Temperaturen liegen, so ergibt sich der Nachteil, daß Meßfehler durch die Wärmeausdehnung an. dem Band anliegender Tastorgane auftreten.Are tapes measured with such devices, which on higher Temperatures are, there is the disadvantage that measurement errors due to thermal expansion at. the band of touching organs occur.

Erfindungsgemäß wird daher ein Banddicken-Meßgerät mit an dem zu messenden Band anliegen den Tastorganen vorgeschlagen, das dadurch gekennzeichnet ist, daß die Temperatur der Tastorgane der des durchlaufenden Bandes angleichbar ist. Durch diese Maßnahme werden die- Anwärmfehler der Tastorgan während der Messung vermieden. Zweckmäßig werden die Tastorgane mittels elektrischer Heizelemente aufgeheizt, wobei die Temperatur regelbar und ablesbar ist. Um -eme Aufheizung der die Tastorgane aufnehmenden Hebelarme zu vermeiden, sind die Tastorgane wärmeisolierend in diesen angeordnet. According to the invention, therefore, a strip thickness measuring device is used with the to measuring tape abut the tactile organs proposed that is characterized is that the temperature of the tactile organs can be matched to that of the continuous strip is. This measure eliminates the heating errors of the feeler during the measurement avoided. The tactile organs are expediently heated up by means of electrical heating elements, whereby the temperature can be regulated and read. To -eme heating of the tactile organs To avoid receiving lever arms, the tactile organs are heat-insulating in them arranged.

An Hand der Zeichnung sei ein Ausführungsbeispiel näher beschrieben. Die Enden der Hebel 1 und 2 tragen Tastorgane 3 und 4, zwischen denen das zu messende Band 5 hindurchgleitet. Im Innern der Tastorgane 3 und 4 sind elektrische Heizelemente angeordnet, an die über die Leitungen 6 bi5 9 eine Spannung gelegt wird. Um Erwärmungen der Hebelarme I 11nd 2 zu vermeiden und die Heizleistung niedrig zu halten, ist zwischen diesen und den Tastorganen ein wärmedämmender Isolierstoff 10 und 11 angeordnet. An exemplary embodiment will be described in more detail with reference to the drawing. The ends of the levers 1 and 2 carry sensing elements 3 and 4, between which the one to be measured Band 5 slides through. Inside the tactile elements 3 and 4 are electrical heating elements arranged, to which a voltage is applied via the lines 6 bi5 9. About warming to avoid the lever arms I 11nd 2 and to keep the heating power low A heat-insulating insulating material 10 and 11 is arranged between these and the tactile organs.

Die Tastorgane werden vor der Messung auf die Temperatur des Bandes gebracht, so daß Meßfehler ausgeschlossen sind. Der Erfindungsgegenstand ist jedoch nicht auf Tastorgane mit gleitenden Flächen beschränkt. Auch Banddickenmesser mit Tastrollen können vorteilhaft nach der Erfindung ausgebildet werden. The tactile organs are measured on the temperature of the tape before the measurement brought so that measurement errors are excluded. However, the subject matter of the invention is not limited to tactile organs with sliding surfaces. Also strip thickness gauge with Sensing rollers can advantageously be designed according to the invention.
