Parallel Connection; Emc Protection - Hbm Pw27A Notice De Montage

5.5

Parallel connection

Only single point load cells with an aligned output (nominal (rated) sensitivity
and output resistance) are suitable for parallel connection. This option is not
available with type PW27 single point load cells.
5.6

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
connection cable shield is connected to the shielded housing of the electronics.
