Aufbau einer neuartigen Kraft-Normalmesseinrichtung für den Bereich 1 mN bis 2 N

(PresseBox) (Braunschweig, )
Die Kraft-Normalmesseinrichtungen der PTB dienen zur Darstellung der Einheit Newton von bisher 0,5 N bis 16,5 MN. Um diesen Messbereich zu kleineren Kräften hin zu erweitern, wurde eine neue Einrichtung in Betrieb genommen. Zur Rückführung werden statt herkömmlicher Belastungskörper moderne elektromagnetisch kompensierte Wägezellen verwendet. So können Kraftaufnehmer im Bereich von 1 mN bis 2 N mit bekannter Messunsicherheit kalibriert werden.

Der Fachbereich Festkörpermechanik bietet als Dienstleistung für die Industrie, für Kalibrierlaboratorien und andere Anwender an, Referenz-Kraftaufnehmer normgemäß zu kalibrieren. Zu diesem Zweck werden Kraft-Normalmesseinrichtungen betrieben, die es erlauben, die Kraft in der Einheit Newton im Internationalen Einheitensystem (SI) rückzuführen. Von
