RESEARCH FOR A NATIONAL FORCE STANDARD MACHINE IN THE RANGE FROM MICRO NEWTON TO NEWTON RELYING ON FORCE COMPENSATION

Jens Illemann, Rolf Kumme
Abstract:
Electromagnetically compensated balances (ECB) are reliable and well-established weighing instruments. As completely electromagnetically compensated types they are commercially available with mass ranges from two grams to several kilograms. They also represent a highly stable and linear scale for force. In this publication it will be shown how ECBs can be used for force standard machines (FSM) having a range of a few Newtons and a feed-back stabilized resolution of single micro Newtons. Moreover, such FSMs conform to the future requirements of continuous calibration.
