Can i use a 1.0Sq. mm signal cable to transmit a load cell output signal from the field to control room at an opproximate distance of 200 mtrs" what are the possible defects that can occurs on the receiving end.

Can i get specfication for the Load cell cable?

For a typical cell your cable should be shielded with 6 wires (3 pair)

Pair 1 from the control room to power the cell (excitation)

Pair 2 to bring back the cell output

Pair 3 to read back the cell excitation voltage. Pair 3 is normally connected to the same cell terminals as pair 1 and reads the actual voltage applied across the cell. As you know the cell output is rated in mV/V so it's important to ignore the voltage drop in pair 1

I have often used twisted pair instrument cable for this purpose however a 6 conductor shielded will also work.

If your cell is not used for a weigh scale and accuracy is not required you may get away with just 4 conductor shielded.

Post your systems Make & Model, you might get a clearer answer. Most system manuals show how to extend the cell cables

Good luck
