Parallel Connection Of More Than One Transducer; Connections Using The Four-Wire Technique; Cable Extension - HBM C2 Notice De Montage

Wiring code (6‐wire-technique)
Fig. 6.1 Transducer with six‐core cable

Parallel connection of more than one transducer

The transducers are connected in parallel electrically by joining together the
core ends of the transducer connection cables having the same color.
CAUTION
An overload of individual load cells cannot be detected from the output signal.
6.4 Connections using the four‐wire technique
With connections to amplifiers using the four‐wire technique the cores bu (blue)
and gn (green) should be connected together, as should bk (black) and gr
(grey). Please take in account that this causes deviations to the sensitivity and
the temperature coefficient of sensitivity that this causes.

Cable extension

Extension cables must be screened and of the low capacitance type. We rec­
ommend the use of HBM cables which fulfil these requirements. For cable ex­
