TB2
Please note, when measuring dynamic torques:
• The calibration performed for static torques is also valid for dynamic torque
measurements.
• The natural frequency f
the moments of inertia J
TB2's torsional stiffness.
Use the equation below to approximately determine the natural frequency f

• The oscillation width (peak‐to‐peak) can be max. 200 % (for nominal (rated)
torques 3 to 10 kN⋅m=160 %) of the nominal (rated) torque designated for
the TB2, even under alternating load. The oscillation width must fall within
the loading range specified by -M
ATTENTION
The mechanical limit values must be complied with even in a resonance
situation. The torsional spring stiffness and inertia torque for estimating
the natural frequency can be found in Chap. 9.
