Connecting In Four-Wire And Six-Wire Configurations; Shortening The Cable; Cable Extensions - HBM PW12C3 Serie Notice De Montage

PW12C3... Single point load cells

2.1 Connecting in four-wire and six-wire configurations

When load cells in a six-wire configuration are connected to amplifiers with a
four-wire configuration, the sense leads of the load cells must be connected to
the corresponding excitation leads.

2.2 Shortening the cable

When the 6−wire configuration is used, the load cell's 6−wire cable can be cut
off without impairing measurement accuracy.

2.3 Cable extensions

You must only use shielded, low-capacitance measurement cables to extend
the cables, making sure that there is a proper connection with minimal contact
resistance.
The cable of a six-wire load cell can be extended with a cable of the same type.
