T12CVS8 HBM: public 21
no circumstances should the allowed limits specified for bending moments, lat-
eral and axial forces be exceeded. Due to the T12CVS8 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 adjustment made at the fac-
tory can shift by up to approx. 3% of the characteristic value. If this value is
exceeded, we advise you to check the mounting conditions. If the residual zero
drift when the unit is removed is greater than 1% of the rated output, please
send the transducer back to the Darmstadt factory for testing.
8.2 Conditions on site
The T12CVS8 torque transducer is protected to IP54 according to EN 60529.
Protect the transducer from coarse dirt, dust, oil, solvents and moisture. During
operation, the prev

tions for the security of personnel must
be observed (see Safety instructions).
There is wide ranging compensation for the effects of temperature on the
output and zero signals of the T12CVS8 torque transducer (see specifications
on page 72). This compensation is carried out at static temperatures. This
guarantees that the circumstances can be reproduced and the properties of the
transducer can be reconstructed at any time.
If there are no static temperature ratios, for example, because of the tempera-
ture differences between flange A and flange B, the values given in the specifi-
cations can be exceeded. Then for accurate measurements, you must ensure
static temperature ratios by cooling or heating, depending on the application.
As an alternative, check thermal decoupling, by means of heat radiating ele-
ments such as multiple disc couplings.
8.3 Mounting position
The transducer can be mounted in any position. With clockwise torque, the
output frequency is 10 to 15 kHz (Option 5, code DF1/DU2: 60 kHz to 90 kHz).
In conjunction with HBM amplifiers or when using the voltage output, a positive
output signal (0 V to +10 V) is present.
