Structure and mode of operation

The reference torque measuring disc comprises a measuring body applied

with strain gages and a mounting flange screw fitted to it.

Measuring body

Fig. 3.1: Mechanical structure

When the torque measuring disc is fitted in test benches, the test bench

components (frame, couplings, mounting flanges, screw fittings, etc.), affect

the deflection performance in the shaft run and thus the measuring

characteristics (zero point, sensitivity, reproducibility). The causes for this can

include:

• Additional parasitic loadings such as radial forces, axial forces or bending

moments

• Asymmetrical torque introduction in the transducers
