‘High-precision torque measurement system’ - .PDF file.

The demand for economical drive concepts for vehicles that meet environmental guidelines is always accompanied by an increase in requirements for the test equipment. Highly dynamic, high-resolution torque measurements in the shaft train are essential for designing and optimising engine-transmission combinations. Reproducibility is very good with modern torque transducers with strain gauges. The overall accuracy of the torque measuring system is basically determined by the mechanical disturbance variables and by thermal and humidity effects that have not been compensated. The resolution limit, as the total of errors resulting from the measuring body and the strain-gauge application that cannot be compensated, exceeds the metrological possibilities of the electronics currently used in rotating transducers, with a DC amplifier, analogue signal conditioning and frequency analogue signal transmission. This paper from HBM discusses the development of a contactless torque measuring system with a carrier frequency amplifier.
