Technical article: Mike Might Know — making sense of load cell sense connections - .PDF file.

In some applications, the distance between a load cell or force transducer and the measuring instrument may be considerable, possibly hundreds of metres. The voltage drop along the connecting cable of a four-wire connection system and its associated temperature coefficient of resistance may contribute significantly to the overall system error. This additional error can be eliminated by the use of the six-wire connection technique where the voltage is sensed locally to the load cell and maintained at a constant level by a remote sensing power supply that automatically compensates for cable resistance variations. This article from Sherborne Sensors provides further information.
