Dynamic Calibration Of Torque Transducers Applying Angular Speed Steps

Abstract

The traceability of the torque quantity finds a gap when there is a regime with torque variation rates, once the traditional calibration methods define the references to be of null torque variation (static) or of low torque rate (continuous). This paper presents a method for providing torque traceability to rotating sensors under higher torque variation rates. The principle is presented and then followed by the method description for obtaining the calibration results.
