Parallel Connection (Option); Emc Protection - HBM PW12C3 Serie Notice De Montage

2.4 Parallel connection (option)

Only single point load cells with an aligned output (nominal (rated) sensitivity
and output resistance) are suitable for parallel connection. Many of HBM's
single point load cell types are available with this option.

2.5 EMC protection

Electrical and magnetic fields often induce interference voltages in the
measuring circuit. Therefore:
S Use shielded, low-capacitance measurement cables only
(HBM cables fulfill both conditions)
S Do not route the measurement cables parallel to power lines and control
circuits.
If this is not possible, protect the measurement cable, in rigid steel conduits,
for example
S Avoid stray fields from transformers, motors and contact switches
To ensure the best EMC protection, the load cell, together with the connection
cable and the subsequent electronics, should be placed in a shielded housing.
Exception:
Load cells with shielded, round cables are EMC-tested in accordance with EC
directives and identified by CE certification. But you must make sure that the
shield of the connection cable is connected to the shielding housing of the
electronics.
