4.1 Important

precautions

during

installation

NOTE

A T40HS 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.

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

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 prestressing 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 T40HS 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 T40HS torque flange's high torsional stiffness, dynamic shaft train

changes are kept to a minimum.
