Shortening The Cable; Extension Cable; Parallel Connection; Emc Protection - HBM PW29P Series Mounting Instructions

Important
The TK value given in the specifications for the transducer therefore does not
c
apply for the cable and transducer combination when connection is in a
four‐wire configuration, where the cable percentage must be added.

4.3 Shortening the cable

If the transducer is connected to an amplifier in a six‐wire configuration, the
transducer cable can be shortened as required, without adversely affecting
the measurement accuracy.

4.4 Extension cable

Only use shielded, low‐capacitance measurement cables for extending.
Ensure that connection is perfect, with a low contact resistance.
The cable of a six‐wire transducer can be extended with a cable of the same
type.

4.5 Parallel connection

Only load cells with an aligned output (nominal (rated) sensitivity and output
resistance) are suitable for parallel connection. This option is not available
with type PW29P load cells.

4.6 EMC protection

Important
The load cells with shielded, round cables are EMC‐tested in accordance with
EC directives and identified by CE certification. However, you must connect
the shield of the connection cable on the shielding electronics enclosure in
order to achieve EMC protection for the measuring chain.
Electrical and magnetic fields often induce interference voltages in the
measuring circuit. Therefore:
 Use shielded, low‐capacitance measurement cables only (HBM cables
fulfill both conditions).
