Erzeugung eines statischen Drehmoments im Bereich von 1 mN·m bis 1 N·m nach dem Laufgewichtsprinzip

摘要

Torque sensors with a small measurement range up to 1 N·m are part of the different precision devices, for example robot or tools for medical operations and also in nanofabrication. The torque transducers frequently need a calibration for which traceability need to be been proven. According to legal mandate, the national metrological institutes has the task to realize the torque units and to enable the required traceability. This article shows how to generate static torque in the range from1 mN·m to 1 N m according to the new principle. In the future, the main goal is to implement this new idea of torque generation to create a new, more precise torque standard machine (TSM). The new method of static torque generation was also compared with the generation of torque to the state of the art of technogy (PTB torque standard machine, The National Metrology Institute of Germany).
