Description
Es ist bekannt, Zeigerstellungen mit Hilfe von Lichtquellen weithin kenntlich zu machen. Man hat bisher für diesen Zweck z. B. Abdeckbänder oder bewegliche Lichtquellen verwendet, wobei diese Teile durch einen in Abhängigkeit von der Zeigerstellung· gesteuerten Motor o. dgl. verstellt wurden. Diese Ausführungsart ist indessen verhältnismäßig umständlich und kompliziert.It is known that pointer positions can be clearly identified with the aid of light sources do. One has so far for this purpose z. B. masking tapes or movable light sources used, whereby these parts are characterized by a depending on the pointer position controlled motor o. the like. were adjusted. However, this embodiment is proportionate awkward and complicated.
ίο In anderen bekannten Einrichtungen erfolgt die Anzeige durch einen Lichtstrahl, welcher ,von einem mit der Drehachse des Meßsystems verbundenen Spiegel projiziert wird. Diese Anordnung ist aber z. B. zufolge Beschlagens des Spiegels in dampfhaltigen Räumen, dann wegen ungünstiger Fernlesbarkeit im Halbdunkel u. dgl. nicht für alle Betriebsverhältnisse geeignet.ίο In other known institutions the display by a light beam which, from one with the axis of rotation of the Measurement system connected mirror is projected. This arrangement is z. B. according to Fogging of the mirror in steamy rooms, then because of poor remote readability in semi-darkness and the like not suitable for all operating conditions.
Ferner ist es bekannt, leuchtende Bänder zur Anzeige zu benutzen, deren Länge entsprechend der Meßgröße zu- und abnimmt. Die Lichtbänder werden hierbei durch eine Lampenreihe gebildet.It is also known to use luminous bands for display, the length of which is correspondingly the measured variable increases and decreases. The light strips are here by a Row of lamps formed.
Eine andere, namentlich in physikalischen Hörsälen übliche Methode besteht darin, den Zeiger des Meßgerätes in den Strahlengang eines Projektionsapparates einzuführen, so daß das Schattenbild des Zeigers über einer als Bildschirm dienenden Skala spielt.Another method commonly used in physical lecture halls is to use the To introduce the pointer of the measuring device into the beam path of a projection apparatus, so that the silhouette of the pointer plays over a scale serving as a screen.
Gemäß der Erfindung erhält bei einer Anzeigevorrichtung mit Lichtzeiger, bei der in den Weg eines die ganze Skala umfassenden Strahlenbündels ein mit der Drehachse des Meßgerätes verbundener schattenwerfender Körper eingeführt wird, dieser Körper eine derartige Gestalt, daß auf oder neben der Skala ein an sich bekanntes Lichtband von veränderlicher Länge erscheint, wobei die Grenze zwischen Licht und Schatten als Zeigermarke dient.According to the invention, in a display device with a light pointer in which in the path of a bundle of rays encompassing the entire scale coincides with the axis of rotation of the Measuring device connected shadow-throwing body is introduced, this body one such a shape that on or next to the scale a known light band of variable length appears, the boundary between light and shadow as Pointer mark serves.
Die neue Anordnung zeichnet sich durch große Einfachheit und Betriebssicherheit aus und eignet sich insbesondere für Großanzeigeinstrumente, die aus großer Entfernung abgelesen werden. Die scharfe Begrenzung zwisehen Licht- und Schattenreiche gibt den jeweiligen Ausschlag des Meßgerätes weithin sichtbar an, so daß selbst für größere Entfernungen eine genaue Ablesbarkeit erzielt wird.The new arrangement is characterized by great simplicity and operational reliability and is particularly suitable for large display instruments that can be read from a great distance will. The sharp delimitation between the realms of light and shadow gives the respective The rash of the measuring device is visible from afar, so that even for greater distances accurate readability is achieved.
Eine weitere Vervollkommnung besteht darin, daß die Lichtquelle gleichzeitig in an sich bekannter Weise das vergrößerte Bild einer in den Strahlengang eingeführten, auf durchscheinendem Stoff angebrachten Skala auf den Bildschirm projiziert.Another improvement is that the light source is on at the same time In a known manner, the enlarged image of an introduced into the beam path on The scale attached to the translucent fabric is projected onto the screen.
