CAUTION
Check the effect on speeds and natural torsional oscillations critical to
bending, to prevent the transducer being overloaded by increases in
resonance.
NOTE
Even if the unit is installed correctly, the zero point adjustment made at
the factory can shift by up to approx. 2 % of the characteristic value. If
this value is exceeded, we advise you to check the mounting conditions.
If the residual zero offset when the unit is removed is greater than 1 % of
the characteristic value, please send the transducer back to the
Darmstadt factory for testing.
For correct operation, do, in any case, comply with the mounting
dimensions.

3.1 Conditions on site

The T40 torque flange must be protected against coarse dirt particles, dust,
oil, solvents and humidity. During operation, the prevailing safety regulations
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 T40 torque flange (see specifications).
If there are no static temperature ratios, for example, because of the
temperature differences between the measuring body and the flange, the
values given in the specifications can be exceeded. So for accurate
measurements, static temperature conditions must then be obtained by
cooling or heating depending on the application. As an alternative, check
thermal decoupling, by means of heat radiating elements such as multiple
disc couplings.

3.2 Mounting position

The transducer can be mounted in any position. With clockwise torque, the
output frequency is 60 to 90 kHz (Option 5, Code SU2: 10 kHz to 15 kHz;
HU2: 240 kHz to 360 kHz). In conjunction with HBM amplifiers or when using
the voltage output, a positive output signal (0 V to +10 V) is present.
