ELECTRICAL CONNECTION

7.1

General information

To make the electrical connection between the torque transducer and the amplifier, we
recommend using shielded, low-capacitance measurement cables from HBM.
With cable extensions, make sure that there is a proper connection with minimum contact
resistance and good insulation. All plug connections or swivel nuts nuts must be fully
tightened.
Do not route the measurement cables parallel to power lines and control circuits. If this
cannot be avoided (in cable pits, for example), maintain a minimum distance of 50 cm
and also draw the measurement cable into a steel tube.
Avoid transformers, motors, contactors, thyristor controls and similar stray-field sources.
Notice
Transducer connection cables from HBM with attached connectors are identified in accor­
dance with their intended purpose (Md or n). When cables are shortened, inserted into
cable ducts or installed in control cabinets, this identification can get lost or become con­
cealed. If this is the case, it is essential for the cables to be re-labeled!
7.2

Shielding design

The cable shield is connected in accordance with the Greenline concept. This encloses
the measurement system in a Faraday cage. It is important that the shield is laid flat on
the housing ground at both ends of the cable. Any electromagnetic interference active
here does not affect the measurement signal.
In the case of interference due to potential differences (compensating currents), operat­
ingvoltage zero and housing ground must be disconnected on the amplifier and a poten­
tial equalization line established between the stator housing and the amplifier housing
(copper conductor, 10 mm
