5 Mechanical installation
5.1 Important precautions during installation
NOTE
A torque flange is a precision measurement element and therefore needs careful
handling. Dropping or knocking the transducer may cause permanent damage. Make
sure that the transducer cannot be overloaded, even while it is being mounted.
• Handle the transducer with care.
• Check the effect of bending moments, critical speeds and natural torsional
oscillations, to prevent the transducer being overloaded by increases in
resonance.
•
Make sure that the transducer cannot be overloaded.
W ARNING
There is a danger of the transducer breaking if it is overloaded. This can cause danger for
the operating personnel of the system in which the transducer is installed .
Implement appropriate safety measures to avoid
overloads and to protect against resulting
dangers
.
• Use a screw locking device (medium strength, e.g. LOCTITE No. 242) to glue the
screws into the counter thread to exclude pre-stressing loss due to screw
slackening, if alternating loads are to be expected.
• Comply with the mounting dimensions to enable
correct operation.
An appropriate shaft flange enables the torque flange 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 should the permissible
limits specified for bending moments, lateral and longitudinal forces be exceeded. Due to
the torque flange's high torsional stiffness, dynamic shaft train changes are kept to a
minimum.
