Structure and mode of operation

3.1 Mechanical structure

The reference torque measuring disc comprises a measuring body applied
with strain gages and a mounting flange screw fitted to it.

4.1 General installation notes

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
