Description

Elektrisches Ineßinstrument mit permanentem IKagneten, insbesondere Oszillograph. Gemäß der Erfindung wird der Eisenweg des permanenten Magneten eines Meßinstrumentes beim Entfernen des Meßsystems selbsttätig geschlossen. Man kann dies beispielsweise dadurch erreichen, daß man ein Eisenstück mit dem Meßsystem derart verbindet, daß es sich beim Entfernen dieses Systems selbsttätig zwischen die Pole legt.Electric measuring instrument with permanent magnet, in particular Oscillograph. According to the invention, the iron path of the permanent magnet becomes one Measuring instrument automatically closed when the measuring system is removed. One can this can be achieved, for example, by placing a piece of iron with the measuring system connects in such a way that when this system is removed it automatically switches between lays the pole.

Die Abbildung zeigt als Ausführungsbeispiel der Erfindung einen Oszillographen. i ist der permanente Magnet, 2 das Meßschleifensystem. 3 ist ein Rohr vom gleichen Durchmesser wie das Meßschlei£ensystem, in dem sich der Eisenkörper q. befindet. Dieser Körper steht unter der Kraft der Feder 5 und wird gegen das Meßschleifensystem gedrückt. Wird das Meßsystem, beispielsweise zum Reinigen o. dgl., entfernt, so drückt die Feder 5 selbsttätig den Eisenkörper ¢ zwischen die Polschuhe des Magneten und stellt somit einen guten Eisenschluß her. Durch die Einrichtung gemäß der Erfindung wird erreicht, daß der permanente Magnet selbst beim Entfernen des Meßsystems nicht schwächer wird.As an embodiment of the invention, the figure shows an oscilloscope. i is the permanent magnet, 2 the measuring loop system. 3 is a pipe of the same Diameter like the measuring loop system in which the iron body q. is located. This body is under the force of the spring 5 and is against the measuring loop system pressed. If the measuring system is removed, for example for cleaning or the like, so the spring 5 automatically presses the iron body ¢ between the pole shoes of the magnet and thus creates a good iron connection. By the device according to the invention it is achieved that the permanent magnet does not even when the measuring system is removed gets weaker.
