Dynamometrisches Messinstrument mit magnetischer Dämpfungsvorrichtung.
Die Erfindung betrifft die Anordnung einer magnetischen Dämpfungsvorrichtung an dynamometrischen Messinstrumenten, vorzugsweise solchen mit Eisen im magnetischen Feld. Gemäss der Erfindung wird die Dämpfungsvorrichtung unterhalb der aus ferromagnetischem Material bestehenden Grundplatte des Instrnmentensockels angeordnet. Es wird auf diese Weise das System gegen jede Beeinflussung durch die permanenten Magnete der Dämpfungsvorrichtung geschützt, andererseits aber auch der Dämpfungsmagnet vor Entmagnetisierung durch die in dem Instrument fliessenden Ströme bewahrt.
Auf der Zeichnung ist eine Ausführungsform des neuen Messinstrumentes dargestellt, und zwar zeigt Fig. 1 einen Längsschnitt, Fig. 2 einen Grundriss.
Die eine Spule a des dynamometrischen Instrumentes ist auf einem ringförmigen Eisenkern b verteilt, welcher in seinem Innern einen festen Kern c aufnimmt. In dem Luftspalt zwischen beiden bewegt sich die rahmenförmig gewickelte zweite Spule d. Die mit dieser beweglichen Spule d verbundene Instrumentenachse e tritt durch die aus Gusseisen. Eisenblech oder dgl. bestehende Grundplatte 9 des Instrnmentensockels s hindurch und tragt innerhalb des Sockelraumes eine Metallscheibe f, welche sich zwischen den Pollen/2 eines oder mehrerer Dauermagnete m bewegt und bei der Einstellung des S) stemes in bekannter Weise eine dämpfende Wirkung ausübt.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Dynamometric measuring instrument with magnetic damping device.
The invention relates to the arrangement of a magnetic damping device on dynamometric measuring instruments, preferably those with iron in the magnetic field. According to the invention, the damping device is arranged below the base plate of the instrument base, which is made of ferromagnetic material. In this way, the system is protected against any influence from the permanent magnets of the damping device, but on the other hand the damping magnet is also protected from demagnetization by the currents flowing in the instrument.
The drawing shows an embodiment of the new measuring instrument, namely FIG. 1 shows a longitudinal section and FIG. 2 shows a plan.
One coil a of the dynamometric instrument is distributed on an annular iron core b, which receives a solid core c in its interior. The frame-shaped wound second coil d moves in the air gap between the two. The instrument axis e connected to this movable coil d passes through the cast iron. Sheet iron or the like. Existing base plate 9 of the instrument base s through and carries a metal disk f within the base space, which moves between the pollen / 2 of one or more permanent magnets m and when the S) stem is set, it has a damping effect in a known manner.
** WARNING ** End of DESC field may overlap beginning of CLMS **.
