<Desc/Clms Page number 2>
EMI2.1
Anordnung nur Metalle gewählt, welche ferromagnetische Eigenschaften zeigen, z. B. Eisen in Verbindung mit Eisen-Nickel-Legierungen oder verschiedene Nickellegierungen.
Der Mehrmetallstreifen könnte jedoch auch so angeordnet sein, dass er den Gegenpol bewegt. In diesem Falle muss bei der Zusammensetzung des Mehrmetallstreifens auf die magnetische Leitfähigkeit des Me. hrmetallstreifens keine Rücksieht genommen werden.
Auch könnte, wie schon erwähnt, an Stelle eines Mehrmetallstreifens ein nicht aus mehreren Metallen zusammengesetzter, beispielsweise nur aus Zink bestehender Stab in der beschriebenen Art vorgesehen sein.
Die Einrichtung ist selbstverständlich bei Einphasen- und Mehrphaseninduktionsmessgeräten anwendbar.
PATENT-ANSPRÜCHE :
1. Anordnung zur Änderung des Temperaturkoeffizienten bei Induktionsmessgeräten mit Triebsystemen mit wenigstens einem Gegenpol, dadurch gekennzeichnet, dass die Gegenpolwirkung durch eine temperaturabhängige Einrichtung selbsttätig änderbar ist.
EMI2.2
wirkung ein Mehrmetallstreifen (10) dient.

EMI2.1
Arrangement only selected metals which show ferromagnetic properties, e.g. B. Iron in conjunction with iron-nickel alloys or various nickel alloys.
However, the multi-metal strip could also be arranged in such a way that it moves the opposite pole. In this case, when composing the multi-metal strip, the magnetic conductivity of the metal strip does not have to be taken into account.
As already mentioned, instead of a multi-metal strip, a rod not composed of several metals, for example consisting only of zinc, could be provided in the type described.
The device can of course be used with single-phase and multi-phase induction meters.
PATENT CLAIMS:
1. Arrangement for changing the temperature coefficient in induction measuring devices with drive systems with at least one opposite pole, characterized in that the opposite pole effect can be changed automatically by a temperature-dependent device.
EMI2.2
effect a multi-metal strip (10) is used.
