Countermeasures:
1. Optimum alignment of the shaft run (note alignment
data in the Specifications!).
As long as you do not exceed the permissible limits
for bending moments, transverse force and longitud­
inal force, no special couplings or other measures are
required to install the reference torque measuring‐disc
(effect on the measurement result approx. 1 % of
nominal torque).
2. If you cannot achieve the requisite alignment accur­
acy, use non‐interacting couplings.
3. Keep the weight of the shaft sections acting on the
torque measuring‐disc as low as possible.
Depending on the design of the test bench, decoupling
measures with torsionally stiff but pliable torsion bars
may be necessary.
Different stiffness conditions
If the stiffness conditions in the shaft run (near the torque
measuring‐disc) differ to the conditions during calibration
in the HBM normal measuring device, this can change
the torque introduction to the torque measuring‐disc.
Countermeasures:
1. Keep strictly to the prescribed fastening bolt tightening
torques.
2. Use high‐strength or hardened adaptation compon­
ents, especially close to the torque introductions and
torque outlets of the torque measuring‐disc.
