Wiring a Four-Wire Strain Bridge Sensor When Four-Wire Measurement
Configured
Where possible, four core cable should be used to connect the strain bridge sensor
directly to the PSDS connector.
If the cable has twisted pairs, refer to the wiring table above where it is indicated which
connections should share a twisted pair. Note: shield connections are described
further on in this section. Also, the extra two cores required for TEDs connection (If
used) are not shown in the diagram.

Shield Connection

All connection cables should be shielded/screened and the recommended shield
connection point is as follows:
Where Strain Bridge Sensor Chassis is Metallic (or surrounding strain bridge sensor
structure)
Cable shield should be connected to the strain bridge sensor chassis and remain
unconnected at the PSDS end.
