   Bei dem Ausführungsbeispiel nach Fig. 6-8 ist das feste Feldsystem 1. 13, 1-1 wiederum als unterteilter Zylinder ausgebildet. In der Mittelachse 14 (Fig. 6) des Zylinders ist die Drehachse des beweglichen Systems gelagert, die exzentrisch die wirksame Zylinderfläche 15 trägt. Der Innenzylinder hesteht aus dünnem Blech und ist auf seiner ganzen Oberfläche spannungsführend. Die Kapazität des Innenzylinders gegen einen Sektor ändert sich je nach seiner Lage infolge der Abstandsänderung der spannungführenden Teile. Die festen Sektoren haben diesmal eine Gestalt, die in Fig. 8 in der Abwicklung dargestellt ist. Die

   In the embodiment according to FIGS. 6-8, the fixed field system 1. 13, 1-1 is again designed as a subdivided cylinder. The axis of rotation of the movable system, which eccentrically supports the effective cylinder surface 15, is mounted in the central axis 14 (FIG. 6) of the cylinder. The inner cylinder is made of thin sheet metal and is live on its entire surface. The capacity of the inner cylinder against a sector changes depending on its position as a result of the change in distance between the live parts. The fixed sectors this time have a shape that is shown in Fig. 8 in the development. The

 and the movable coverings changes with increasing deflection of the instrument, u. in such a way that the pointer deflection is as proportional as possible to the displayed phase angle of the compared voltages.

Claims (1)

2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass der wirksame Teil des beweglichen Systems als Zylindermantel ausgebildet ist, dessen Höhe nicht überall gleich ist. sondern sich wellenförmig ändert, während die festen Sektoren Teile eines Zylinders bind. der dem beweglichen Zylinder konzentrisch gegenüber steht. EMI2.3 EMI2.4 2. Device according to claim 1, characterized in that the effective part of the movable system is designed as a cylinder jacket, the height of which is not the same everywhere. but changes in a wave shape as the solid sectors bind parts of a cylinder. which is concentrically opposite the movable cylinder.
