7.1 Important precautions during installation
NOTE
A torque flange is a precision measuring element and therefore needs careful
handling. Dropping or knocking the transducer may cause permanent
damage. Make sure that the transducer cannot be overloaded, including while
it is being mounted.
Handle the transducer with care.
Check the effect of bending moments, critical rotational speeds and natural
torsional vibrations, to prevent the transducer being overloaded by
resonance sharpness.
Make sure that the transducer cannot be overloaded.
WARNING
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 threadlocker (medium strength, e.g. LOCTITE) to glue the screws
into the counter thread to exclude prestressing loss due to screw
slackening, in the event of alternating loads.
Comply with the mounting dimensions to enable correct operation.
An appropriate shaft flange enables the T12 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 T12 torque
flange’s high torsional stiffness, dynamic shaft train changes are kept to a
minimum.
