Vergleichs- bzw. Verzweigungswiderstand für elektrische Meßbrücken.Comparison or branch resistance for electrical measuring bridges.
Der Zweck der Erfindung besteht darin, die bei Vergleichs- bzw. Verzweigungswiderständen für elektrische Meßbrücken leicht mögliche unrichtige Ablesung des Verhältnisses dadurch zu vermeiden, daß dasselbe unmittelbar als Quotient ablesbar ist. Dies wird durch folgende Einrichtung erreicht.The purpose of the invention is that of comparison or branching resistors incorrect reading of the ratio is easily possible for electrical measuring bridges to avoid that the same can be read off directly as a quotient. This is achieved through the following setup.
Unter einer schwarzen Glasplatte A mit dem freien Feld abcd und dem Strich e ίο drehen sich die Kurbeln / und g der Widerstände um die Achsen h und i, an denen auch die Sektoren k und / angebracht sind.Under a black glass plate A with the free field abcd and the line e ίο, the cranks / and g of the resistors rotate around the axes h and i, on which the sectors k and / are also attached.
Letztere befinden sich unmittelbar unterThe latter are just below
der Glasplatte und sind mit Ziffern versehen, welche die Größe der Widerstände angeben.the glass plate and are provided with numbers that indicate the size of the resistors.
Die Ziffern, welche die Größe der eingeschalteten Widerstände bezeichnen, erscheinen in dem freien Felde über und unter dem Striche.The numbers that indicate the size of the switched on resistors appear in the open field above and below the line.
Für die Erfindung ist es gleichgültig, ob die Zahlen über und unter einem Bruchstrich oder rechts und links eines Divisionszeichens erscheinen, wie in Fig. 2 gezeigt ist.For the invention it does not matter whether the numbers above and below a fraction line or appear to the right and left of a division mark as shown in FIG.
