Mathematical representation of reference torque transducers in partial-range regimes

A. Brüge

Abstract

Investigations with regard to the mathematical description of reference torque transducers used in comparison calibration facilities are described. A method is presented which uses only the direct loading calibration data of a torque transducer in the full range in order to calculate its behaviour in any reasonable partial range. Examinations of typical reference torque transducers demonstrate how to find transducers which are qualified for this calculation method and provide estimations of the possible effects on the measurement uncertainty caused by the calculation of the partial-range behaviour.
