NEW METHOD FOR ONLINE COMPENSATION OF PARASITIC EFFECTS IN FORCE MEASUREMENT

摘要

The proper evaluation and classification of force realizing machines requires transfer force transducers providing measurement results that ensure reproducibility and minimum measurement uncertainty even with changing mounting conditions. This article is to introduce a transfer force transducer which -due to its mechanical and electrical structure - ensures a reduced mounting-position dependent measurement uncertainty. By using a multi-channel measuring amplifier system and applying a compensating algorithm for the axial force signal, a further significant increase in reproducibility can be achieved.
