Advantage of carrier frecquency in contactles high precision torque measurement systems

S. Kuhn

Abstract

This paper describes the advantage of carrier frequency amplifiers in rotating torque flanges. It gives an overview of the systematic effects and random errors which disturb the torque measurement and shows how the measurement errors can be suppressed by means of carrier frequency technology. The resulting high reproducibility and linearity of the new torque flange with digital signal processing and transmission is shown in torque and temperature plots.
