Load-carrying capacity
Nominal (rated) torque can be exceeded statically up to the torque limit. 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
Measuring dynamic torque
The torque flange can be used to measure static and dynamic torques. The
following apply to the measurement of dynamic torque:
S
The T40FH calibration performed for static measurements is also valid for
dynamic torque measurements.
S
The natural frequency f

of the mechanical measuring arrangement
depends on the moments of inertia J

and J
2
of the connected rotating
masses and the torsional stiffness of the T40FH.
