11 Load-carrying capacity
Nominal (rated) torque can be exceeded statically up to the limit torque. If the
nominal (rated) torque is exceeded, additional irregular loading is not
permissible. This includes longitudinal forces, lateral forces and bending
moments. Limit values can be found in the “Specifications” chapter (Chapter
15, page 56).
Measuring dynamic torque
The torque transducer is suitable for measuring static and dynamic torques.
The following apply to the measurement of dynamic torque:
The T12 calibration run for static measurements is also valid for dynamic
torque measurements.
The natural frequency f
0
of the mechanical measuring system depends on
the moments of inertia J
1
and J
2
of the connected rotating masses and the
T12’s torsional stiffness.

The maximum oscillation width is 200% (measuring range 3 kN@m to 10
kN@m: 160%) of the typical nominal (rated) torque for the T12 (see
“Specifications”, page 56) The oscillation width must lie between the
maximum upper and lower torques of the defined loading range. The same
also applies to transient resonance points.
