Electrical connection
3.1 General instructions
We recommend to use shielded, low−capacitance cable from HBM for the elec-
trical connection between torque transducer and measuring amplifier.
With cable extensions it is important to ensure that a good connection is pro-
vided, with minimum contact resistance and good insulation. All plug connec-
tions or cap nuts have to be tightened firmly.
Do not route measurement cables in parallel to power lines and control circuits.
If this is not possible (for example in cable ducts), maintain a minimum dis-
tance of 50 cm and protect the cable with a steel tube.
Avoid transformers, motors, contactors, thyristor controllers and similar
sources of stray fields.
3.2 Connector
The transducer is equipped with a permanent housing connector.
It can be connected to the relevant measurement electronics by using the
transducer connection cable (accessories, see Page 19). The pin assignment
for the transducer connection cable can be found in the following table:
