Mechanical installation

WARNING
Handle the torque flange carefully! The transducer could suffer
permanent damage from mechanical shock (dropping), chemical effects
(e.g. acids, solvents) or thermal effects (hot air, steam).
With alternating loads, you should cement the rotor connection screws
into the mating thread with a screw locking device (medium strength) to
exclude prestressing loss due to screw slackening.
An appropriate shaft flange enables the T10FS torque flanges to be mounted
directly. It is also possible to mount a joint shaft or relevant compensating
element directly on the rotor (using an intermediate flange when required).
Under no circumstances must the permissible limits specified for bending
moments, lateral and longitudinal forces be exceeded. Due to the T10FS
torque flanges' high torsional stiffness, dynamic changes on the shaft train are
minimized.
IMPORTANT
The effect on critical bending speeds and natural torsional vibrations
must be checked to avoid overloading the measurement flanges due to
the resonance stepup.
NOTE
Even if the unit is installed correctly, the zero point adjustment made at
the factory can shift by approx. "150 Hz. If this value is exceeded, we
advise you to check the mounting conditions. If the residual zero offset
when the unit is removed is greater than "50 Hz, please send the
transducer back to the Darmstadt factory for testing.
For correct operation, comply with the mounting dimensions (see Page
64).
