Notes on cable routing

Electrical and magnetic fields often cause the introduction of disturbing volt­
ages into the measuring circuit.
Please note the following hints:
S Use only screened, low capacitance measuring cable (cable from HBM ful­
fils these requirements).
S Do not lay the measuring cable parallel to power and control lines. If this is
not possible (e.g. in cable ducts), the measuring cable can be protected,
e.g. by steel conduit.
S The stray fields of transformers, motors and contactors must be avoided.

Connection technique

Strain‐gage based load cells can be connected to:
S carrier frequency
S DC‐measuring amplifiers.
The transducer connection is implemented using the six-wire technique. The
connection assignment can be taken from the following illustration (Fig. 6.1)
