A novel lead-wire-resistance compensation technique using two-wire resistance temperature detectors is presented here. This technique compensates the effect of both identical and nonidentical lead-wire resistances in the measurements. The measured error is comparable with both conventional three-wire and four-wire techniques and lies within plusmn0.15% of reading the resistance. The proposed technique also reduces self-heating by 50%. It is quite conveniently adaptable in industry
