"äteßwertaufnehmer für Wege, Winkel, Weg- und Winkelgeschwindigkeit sowie Weg- und Winkelbeschleunigung"Äteßwertaufnehmer for distances, angles, path and angular velocity as well as path and angular acceleration

Die Erfindung betrifft einen Meßwertaufnehmer für Wege, Winkel, Weg- und Winkelgeschwindigkeit sowie Weg- und Winkelbeschleunigung nach dem Prinzip der optischen Lichtschranke.The invention relates to a transducer for paths, angles, path and angular speed as well as path and Angular acceleration based on the principle of the optical light barrier.

Die bekannten Meßwertaufnehmer sind in ihrem Aufbau kompliziert und deshalb teuer in der Herstellung.The known transducers are complex in structure and therefore expensive to manufacture.

Die Erfindung hat es sich zur Aufgabe gemacht, hier eine Verbesserung dahingehend zu schaffen, daß ein einfacher Aufbau unter weitgehender Verwendung handelsüblicher Bauteile und damit eine kostengünstige Herstellung möglich sind.The invention has set itself the task of creating an improvement to the effect that a simple Construction with extensive use of commercially available components and thus inexpensive production possible are.

Diese Aufgabe wird durch die im Hauptanspruch angeführten Maßnahmen gelöst. Die Unteransprüche kennzeichnen zweckmäßige weitere Ausbildungen.This task is cited in the main claim Measures resolved. The subclaims characterize further expedient developments.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Der erfindungsgemäße Meßwertaufnehmer besteht aus einem Sender una einem Empfänger üblicher Bauart, die durch Lichtleiter 1, 2 unter Einbau einer Lichtschranke miteinander verbunden sind. Die Lichtschranke besteht aus einer Codescheibe oder einem Codelineal 3, die bzw. das sich proportional zu der zu messenden physikalischen Größe bewegt. Das aus dem Senderlichtleiter 1 kommende Licht wird durch die auf der Codescheibe oder dem Codelineal aufgebrachten Helloder Dunkelzonen am Eintritt in den Empfängerlichtlei tar gehindert oder freigegeben. Die Lichtleiter 1, 2 sind Glasoder Kunststoff-Lichtleiter.An exemplary embodiment is shown in the drawing. The transducer according to the invention consists of a transmitter and a receiver of conventional design, which are connected to one another by light guides 1, 2 with the installation of a light barrier. The light barrier consists of a code disk or a code ruler 3, which moves proportionally to the physical quantity to be measured. The light coming from the transmitter light guide 1 is prevented or released from entering the receiver light guide by the light or dark zones applied to the code disk or the code ruler. The light guides 1, 2 are glass or plastic light guides.

Die dadurch entstandene digitale Information in Form von moduliertem Licht im Empfängerlichtleiter 2 ist dem Weg, der Geschwindigkeit und der Beschleunigung des Codelineales und dem Winkel, der Winkelgeschwindigkeit und der Winkelbeschleunigung der Codescheibe proportional und kann einem vom Aufnehmer mehrere Meter entfernten Ort von dem Empfängerlichtleiter 2 entnommen und in elektrische Signale umgewandelt werden.The resulting digital information in the form of modulated light in the receiver light guide 2 is the path, the speed and the acceleration of the code ruler and the angle, the angular velocity and the angular acceleration of the code disk proportional and can taken from the receiver light guide 2 at a location several meters away from the transducer and converted into electrical signals being transformed.

Der Vorteil dieses Meßwertaufnehmers ist außer seinem einfachen Aufbau seine absolute Stö'runanfälligkeit in Bezug auf elektrische und magnetische Felder.The advantage of this transducer, in addition to its simple structure, is its absolute susceptibility to interference in relation to electrical and magnetic fields.

Da vor Ort keine stromführenden Elemente zur Meßwertaufnahme benötigt werden, ist dieses Meßprinzip bevorzugt in explosionsgefährdeten Räumen einsetzbar.Since there are no live elements for recording measurements on site are required, this measuring principle can preferably be used in areas where there is a risk of explosion.
