Connection
Strain‐gauge based Ioad cells can be connected to:
S carrier frequency or
S DC‐measuring amplifiers.
The transducer connection is implemented using the six‐wire technique. The
connection assignment can be taken from the following illustration.

Wiring code (6‐wire‐technique)
Electrical and magnetic fields often induce interference voltages in the mea
surement circuit.
Therefore:
S Use screened low‐capacitance measurement cables only (HBM cables sat
isfy this criterion).
S Do not route the measuring cable parallel to power and control lines. If this
is not possible, protect the measurement cable, e.g. with steel conduit.
S Avoid the stray fields of transformers, motors and conductors.
