Notes on cabling
Electrical and magnetic fields often induce interference
voltages in the measuring circuit. These interferences
arise primarily from power lines lying in parallel to the
measuring leads, but also from contactors or electric mo­
tors in the vicinity. In addition, interference voltages can
be induced galvanically, especially through the grounding
of the measurement chain at several points.
Please follow the instructions below:
S Only use shielded, low-capacitance measurement
cables for extensions (HBM cables fulfill both condi­
tions).
S Do not route measurement cables parallel to power
lines and control circuits. If this is not possible (in
cable pits, for example), protect the measurement
cable with a rigid steel conduit, for example, and keep
it at least 50 cm away from the other cables. The
power lines or control circuits should be twisted (15
twists per meter).
S Avoid stray fields of transformers, motors and con­
tactors.
S Do not ground the transducer, amplifier and indicator
more than once. All the devices in the measurement
chain must be connected to the same grounded con­
ductor.
S The connection cable shield is connected to the trans­
ducer housing.
