Mechanical installation
20 A3276-8.0 HBM: public T40FM
prestressing loss due to screw slackening, in the
event of alternating loads.
S Comply with the mounting dimensions to enable cor
rect operation.
An appropriate shaft flange enables the T40FM 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 T40FM torque flange's
high torsional stiffness, dynamic shaft train changes are
kept to a minimum.
Important
Even if the unit is installed correctly, the zero point adjust
ment made at the factory can shift by up to approx. 0.5%
of the characteristic value. If this value is exceeded, we
advise you to check the mounting conditions. If the resid
ual zero offset when the unit is removed is greater than
1% of the sensitivity, please send the transducer back to
the Darmstadt factory for testing.
5.2 Conditions on site
The T40FM torque flange must be protected against
coarse dirt particles, dust, oil, solvents and moisture.
There is wide ranging compensation for the effects of
temperature on the output and zero signals of the trans
ducer (see Chapter 14 "Specifications"). If there are no
static temperature ratios, for example, because of the
temperature differences between the measuring body
