Description
Elektrisches Profilinstrument Bei den bisher gebräuchlichen Meßinstrumenten wird der jeweilige Meßwert durch die, Stellung eines Zeigers relativ zu ein-er Skala angegeben. Die Abmessungen des über der Skala spielenden Teilesdes quer zu seiner Längsausdehnung -bewegten Zeigers im Verhältnis zu denjenigen der Skala müssen dabei klein gehalten werden, um eine eindeutige Ablesung zu ermöglichen.Electric profile instrument With the previously used measuring instruments the respective measured value is determined by the position of a pointer relative to a scale specified. The dimensions of the part playing above the scale across his Longitudinal extension of the moving pointer in relation to that of the scale must be must be kept small in order to enable a clear reading.
Eine wesentlich bessere Ablesemöglichkeit wird gemäß der vorliegenden Erfindung da-,durch erzielt, daß der vom Meßsystem bewegte Zeiger eine langgestreckte, der Skalaform angepaßte Form besitzt und sich in Richtung seiner Längsausdehnung derart über die Skala bewegt, daß er dieselbe von einer Seite her bis zum Meßwert überdeckt.A much better reading option is according to the present Invention achieved by the fact that the pointer moved by the measuring system has an elongated, the shape of the scale has adapted shape and extends in the direction of its longitudinal extent so moved over the scale that he same from one side to the measured value covered.
In der Zeichnung sind in den Abb. i bis 4 Ausführungsbeispieleder Erfindung schema,-tisch dargestellt, und zwar zeigt Abb. i ein Profilinstrument mit einem Zeiger, Abb. 2 ein;solches mit gegenläufigen Zeigern, Abb. 3 ein Instrument mit parallel über zwei Skalen spielenden Zeigern.In the drawing the invention are shown in FIGS i to 4 embodiments of the schematically represented changing unit, and that is shown in Figure i registered instrument with a pointer, fig 2 a;... Such counter-rotating pointers, Figure 3 an instrument with parallel two. Pointers playing scales.
Bei -der Ausführung nach Abb. i ist i die Instrumentenachse mit dem drehbaren Teil des Meßinstrumentes und 2,der auf der Achse sitzende Zeiger, dessen Länge mindestens der Länge der Skala 3 entspricht.In -the embodiment according to Figure i. I is the instrument axis to the rotatable part of the measuring instrument and 2, the person sitting on the axis pointer, the length of which corresponds at least to the length of the scale 3.
Mit der Veränderung der Meßgröße schiebt sich der langgestreckte Zeiger in Richtung seiner Längsausdehnung mehr oder weniger weit über die Skala vor, wobei eine beispielsweise pfeilförmig gestaltete Spitze über den jeweils anzuzeigenden Skalawert zu liegen kommt. Wie ersichtlich-, ist hierbei (die Länge des sichtbaren Teiles -des Leag gers von gleicher Größenordnung wie die Skalenalymessung, wodurch eine Ablesung aus wesentlich größerer Entfernung ermöglicht wird. Der Beobachter wird hierbei noch durch das subjektiv besonders deutlich empfundeneVergleichsbild. zwischen der jeweiligen Zeigerlänge und der gesamten Skalenabniessung unterstützt.As the measured variable changes, the elongated pointer moves in the direction of its longitudinal extent more or less far beyond the scale, whereby an arrow-shaped tip, for example, above the one to be displayed Scale value comes to rest. As can be seen, here is (the length of the visible Part of the Leag gers of the same order of magnitude as the scale analysis measurement, whereby reading from a much greater distance is made possible. The Observer This is made possible by the subjectively particularly clearly perceived comparison picture. between the respective pointer length and the entire scale dimension.
In Fällen, in welchen eine Meßg-röße angezeigt werden soll, der auch eine Richtung zukommt, können positive -und negativeWerte dieser Meßgröße in einfachster Weise dadurch unterschieden -werden, daß nian, wie in Abb. 2 angedeutet, zwei gegenläufige, entsprechend der vorliegenden Erfindung geformte Zeiger.2,:2a auf der Meßinstrumentenachse anordnet, welche bei positiven und negativen Werten der Meßgröße abwechselnd über der Skala erscheinen, die dann praktischerwei.se mit zwei gegenläufigen Bezifferung gen versehen wird.In cases in which a measured variable is to be displayed, that too one direction, positive and negative values of this measurand can be found in the simplest possible way Be distinguished by the fact that, as indicated in Fig. 2, two opposing, Pointers 2,: 2a shaped according to the present invention on the measuring instrument axis arranges which in the case of positive and negative values of the measured variable alternately over appear on the scale, which then, in practice, have two opposite numbers gene is provided.
Ebenso kann man in Fällen, in denen die Angaben zweier Meßinstrumente, in einem funktionellen Zusammenhang stehen, durch eine geeignete räumliche Anordnung von zwei solchen Instrumenten eine dritte Anzeige gewinnen. In Abb. 3 sind beispielsweise ein Wattrneter 4 und ein Amperemeter 5 mit ihren beiden Skalen unmittelbar nebeneinander angeordnet. Durch die Wahl der Meßbereicheder beiden Instrumente kann man es unter der meist zutreffenden Voraussetzung konstanter Spannung erreichen, daß bei einem Cos #p == i die sichtbare Länge der beiden Zeiger gleich wird. Verschlechtert sich dann der Cos 9, so vergrößert sich die Länge des Stromzeigers gegenüber derjenigen des Leistungszeigers, so daß man in ,diesem Verhältnis ein Maß für den Cos q# hat.Likewise, in cases in which the data from two measuring instruments are functionally related, a third display can be obtained through a suitable spatial arrangement of two such instruments. In Fig. 3 , for example, a Wattrneter 4 and an ammeter 5 with their two scales are arranged directly next to one another. By choosing the measuring ranges of the two instruments, under the most applicable assumption of constant voltage, one can achieve that with a Cos #p == i the visible length of the two pointers is the same. If the cos 9 then deteriorates, the length of the current phasor increases compared to that of the power phasor, so that one has a measure for the cos q # in this ratio.
Bei den beschriebenen Ausführungsbeispielen bewegt sich der Zeiger gegenüber der Skala so, daß seine sichtbare Längge vom N 1 ullwert der Skala entsprechend dem Meßwert zunimmt und umgekehrt. Es ist selbstverständlich ohne weiteres möglich" das Instrument so auszubilden, daß der Zeiger den Rest der Skala vorn anzuzeigenden Meßwert ab überdeckt.In the above embodiments, the pointer of the scale corresponding to the measured value moves relative to the scale so that its visible Längge N 1 ullwert increases and vice versa. It is of course easily possible to design the instrument so that the pointer covers the rest of the scale from the measured value to be displayed.
