9 Loading capacity
Nominal torque can be exceeded statically up to the limit
torque. If the nominal 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,
on Page 91.
9.1 Measuring dynamic torque
The torque flanges can be used to measure static and
dynamic torques. The following rule applies to the
measurement of dynamic torque:
The T10FM calibration made for static measurements
is also valid for dynamic torque measurements.
The natural frequency f

for the mechanical
measuring system depends on the moments of inertia
J

and J

of the connected rotating masses and the
T10FM's torsional stiffness.
Use the equation below to approximately determine the
natural frequency f

The mechanical vibration bandwidth (peak‐to‐peak)
must be no more than 200 % (measuring range
100 NV@m 400 %; measuring range 3 ... 10 kN@m
160 %) of the nominal (rated) torque identified for the
T10FS. The vibration bandwidth must fall within the
