Description

Die Erfindung betrifft elektrische Integratoren, insbesondere für die Strömungsmenge, deren Zählwerk durch zwei als Wirbelstromanker wirkende, magnetisch gebremste Schei-S ben, Pendel o.. dgl. angetrieben wird, wobei die auf die beiden Anker wirkenden Bremsmomente bei der Meßgröße Null gleich sind und sich bei zunehmender Meßgröße in entgegengesetztem Sinne ändern und bei denen eine die Differenz der Ankergeschwindigkeiten auf das Zählwerk übertragende Vorrichtung, z. B. ein Differentialgetriebe, vorgesehen ist. Die Erfindung besteht darin, daß zur Erzeugung der Bremsmomente ein fürThe invention relates to electrical integrators, in particular for the flow rate, whose counter is made up of two magnetically braked Schei-S acting as eddy current armatures ben, pendulum o .. the like. Is driven, the braking torques acting on the two armatures are equal for the measured variable zero and are opposite in the case of an increasing measured variable Change senses and where one is the difference in anchor speeds on the counter transmitting device, for. B. a differential gear is provided is. The invention consists in that for generating the braking torques a for

IS beide Wirbelstromanker gemeinsamer Bremsmagnet vorgesehen ist. Dadurch wird eine besonders einfache Bauart möglich.If both eddy current armatures are provided with a common brake magnet. This creates a particularly simple design possible.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Abb. 1 zeigt eine Ansicht und Abb. 2 eine Seitenansicht, teilweise im Schnitt. Die als Scheiben ausgebildeten Wirbelstromanker S1 und S2 erhalten elektrisch oder mechanisch ein gleiches Antriebsdrehmoment, z. B. durch ein Uhrwerk U, und treiben über ein Differentialgetriebe das Zählwerk Z an. Beide Scheiben laufen zwischen den Polen des permanenten oder elektrischen Magneten M. The drawing shows an embodiment of the invention. Fig. 1 shows a view and Fig. 2 shows a side view, partly in section. The eddy current armatures S 1 and S 2 designed as disks receive electrically or mechanically the same drive torque, e.g. B. by a clockwork U, and drive the counter Z via a differential gear. Both discs run between the poles of the permanent or electric magnet M.

Bei der Meßgröße Null ist die Bremswirkung auf die beiden Scheiben gleich groß, soIf the measured variable is zero, the braking effect on the two disks is the same, see above

daß sie gleiche Umdrehungszahl erhalten, und das durch das Differentialgetriebe geschaltete Zählwerk Z bleibt daher stehen,. Wird der Magnet M durch eine Meßgröße, die größer als Null ist, um die Achsel verstellt, indem 35 dabei die Scheibe S1 in den Magneten M mehr hinein-, die Scheibe S2 dagegen mehr heraustritt, dann erhält S1 ein größeres und S2 ein kleineres Bnemsdrehmoment, so daß die Umdrehungszahl von S1 kleiner wird als die +0 von S2. Die Differenz der beiden Umdrehungen wird über das Differentialgetriebe auf das Zählwerk Z übertragen und als Maß für die Meßgröße benutzt. Erfolgt der Ausschlag des Magneten nach der entgegengesetzten Rieh- 45 tung, so wird die Umdrehungsdifferenz in entgegengesetztem Sinne auf das Zählwerk übertragen. that they get the same number of revolutions, and the counter Z switched by the differential gear therefore stops. If the magnet M is moved around the armpit by a measured variable that is greater than zero, in that the disk S 1 enters the magnet M more while the disk S 2 protrudes more, then S 1 receives a larger and S 2 a smaller braking torque, so that the number of revolutions of S 1 becomes smaller than the +0 of S 2 . The difference between the two revolutions is transmitted to the counter Z via the differential gear and used as a measure for the measured variable. If the magnet is deflected in the opposite direction, the difference in rotation is transferred to the counter in the opposite direction.
