T10FS
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.

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:
S The T10FM calibration made for static measurements
is also valid for dynamic torque measurements.
S The natural frequency f
measuring system depends on the moments of inertia

T10FS. The vibration bandwidth must fall within the
