Vorrichtung zur Erfassung der Stellung von Meßwerkzeigern und anderen Gliedern. Device for detecting the position of measuring dials and other links.
Es ist bekannt, mit Strahlern direkt oder indirekt Schaltelemente zu beeinflussen, je nachdem die Wirkung des Strahlers durch das zu erfassende Glied, beispieleweise einem Meßwerkzeiger, abgeschirmt wird oder nicht. Solche Geräte kann man beispielsweise für Kegelvorgänge verwenden, bei denen proportional der Temperatur der Zeiger eines Meßwerkee ausschlägt und bei Erreichen einer bestimmten Zeigerstellung ein Schaltvorgang ausgelöst werden soll.It is known to directly or indirectly switch elements with radiators to influence, depending on the effect of the radiator through the member to be detected, for example a measuring tool pointer, shielded will or not. Such devices can be used, for example, for cone processes in which the temperature is proportional the pointer of a measuring mechanism deflects and a switching process is to be triggered when a certain pointer position is reached.
Bei Erreichen eines eingestellten Wertes würde der 2eiger dee Meßwerkes den Strahler abschirmen und so seine direkte oder indirekte Wirkung auf das Schaltelement mehr oder weniger aufheben.Upon reaching a set value of 2 s strength dee measuring mechanism would shield the radiator and pick up as its direct or indirect effect on the switching element more or less.
Ausgeführt worden sind solche Geräte einmal durch Kombination einer Lampe mit einem lichtempfindlichen Glied und zum anderen durch die Kombination eines Temperaturßtrahlers mit einem temperaturabhängigen Wideretand. Bei Verwendung von Lampe und lichtempfindlichen Glied war es bisher üblich, die Wirkung des lichtempfindlichen Gliedes durch ein hochempfindliches Beiais oder durch einen Böhrenverstärker zu verstärkenr um einen Schaltvorgang einleiten zu können. Hochempfindliche Relais und Röhrenverstärker sind aber teure und vor allem in ihrer Zeitfeatigkeit fragliche Bauelemente.Such devices have been implemented on the one hand by combining a lamp with a light-sensitive element and on the other hand by combining a temperature radiator with a temperature-dependent resistor. When using the lamp and the light-sensitive element, it has been customary to increase by a highly sensitive Beiais or through an amplifier Böhr r to initiate a switching operation, the effect of the photosensitive member. Highly sensitive relays and tube amplifiers, however, are expensive and, above all, their time capacity is questionable.
Auch die Verwendung von Magnetverstärkern ist vorgeschlagen worden. Eb ist dies jedoch eine Lösung, die bei dem augenblicklichen Stand der Entwicklung bei den Fotowiderständen noch etwas aufwendig ist.The use of magnetic amplifiers has also been suggested. Eb, however, this is a solution that at the moment the development of the photo resistors is still a bit complex.
Bei Verwendung von Temperaturstrahlern und temperaturabhängigen Widerständen wurde meist mit sehr hohen Temperaturen und teilweise unter Zuhilfenahme von Gebläsen gearbeitet. Bas führte zu großen und teuren Aufbauten, die zudem in ihrer Zeitfestigkeit fraglich waren«When using thermal radiators and temperature-dependent resistors the work was mostly carried out at very high temperatures and sometimes with the help of fans. Bas led to great and expensive structures, the fatigue strength of which was also questionable «
Die vorliegende Erfindung löst das Problem, indem die Wirkung des lichtempfindlichen Gliedes oder des temperatürabhängigen Widerstandes zur Steuerung einer Gasentladungsröhre verwandt wird, um einen Schaltvorgang einleiten zu können.The present invention solves the problem by utilizing the effect of the light-sensitive element or the temperature-dependent resistance to control a gas discharge tube is used to initiate a switching process can.
Gasentladungsröhren sind, vor allem in ihrer Ausführung mit kältet Kathode, völlig betriebssichere und zeitfeste Gebilde, die sich in der lechnik in weitestem Maße eingeführt haben. Für die vorliegende Aufgabenstellung können sie sehr klein und damit preiswert gehalten werden.Gas discharge tubes are, especially in their design with cold Cathode, completely reliable and time-stable structures that have become widely used in technology. For the present The task can be kept very small and therefore inexpensive will.
Die Erfindung soll im Folgenden an einem von vielen möglichen Beispielen erläutert werden. Fig. 1 zeigt diese Anordnung.In the following, the invention is intended to be based on one of many possible examples explained. Fig. 1 shows this arrangement.
Der Zeiger eines Meßwerkee schlägt proportional der temperatur aus. An. ihm let die Fahne 1 angebracht, die sich bei Erreichen eines bestimmten Wertee zwischen den Strahler und den als Funktion der Bestrahlung variablen Widerstand 3 schiebt und so die Wirkung des Strahiere 2 auf den Widerstand 3 aufhebt.The pointer of a measuring mechanism deflects proportionally to the temperature. At. let him have the flag 1 attached, which is when reaching a certain Values between the radiator and the resistor 3, which is variable as a function of the irradiation, and thus the effect of the Strafe 2 on resistance 3 cancels.
Der Widerstand J liegt an der Hilfsanode 4 der Gasentladungsröhre Ändert sich der Widerstand 3 hinreichend, so wird der Punkt erreicht, an dem die Gasentladungsröhre 5 zündet und ein Strom durch sie hindurchfließt« Dieser betätigt ein Relais 7, das einen Sehaltvorgang einleitet· 6 ist ein ohmscher Wideretand.The resistor J is connected to the auxiliary anode 4 of the gas discharge tube If the resistance 3 changes sufficiently, the point is reached at which the gas discharge tube 5 ignites and a current flows through it introduces · 6 is an ohmic resistance.
