Loading capacity
Nominal (rated) 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" section, on page 41.
9.1 Measuring dynamic torque
The torque transducer is suitable for measuring static and dynamic torques.
The following applies to the measurement of dynamic torque:
• The T10FH calibration performed for static measurements is also valid for
dynamic torque measurements.
• The natural frequency f
pends on the moments of inertia J
and the torsional stiffness of the T10FH.
Use the equation below to approximately determine the natural frequency f

• The mechanical vibration bandwidth must not exceed the values stated in
the specifications (see "Specifications", starting on page 41). The vibration
bandwidth must fall within the load range designated by the upper and
lower maximum torques. The same also applies to transient resonance
points.
