Important
Even if the unit is installed correctly, the zero point adjustment made at the
factory can shift by up to approx. 3% of the sensitivity. 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 sensitivity,
please send the transducer back to the Darmstadt factory for testing.
7.2 Conditions on site
The T12 torque transducer is protected to IP54 according to EN 60529.
Protect the transducer from coarse dirt, dust, oil, solvents and moisture.
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 T12 torque transducer (see specifications on
page 56). 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
temperature differences between flange A and flange B, the values given in
the specifications 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 elements such as multiple disc couplings.
7.3 Mounting position
The transducer can be mounted in any position. With clockwise torque, the
output frequency is 10 to 15 kHz (Option 4, 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.
With counterclockwise torque, the output frequency is 5 kHz to 10 kHz (Option
4, code DF1/DU2: 30 kHz to 60 kHz).
In the case of the rotational speed measuring system, an arrow is attached to
the head of the sensor to clearly define the direction of rotation. When the
transducer rotates in the direction of the arrow, a positive rotational speed
signal is output.
