A new type of nickel resistance round wire was developed for temperature transmitter. Seven kinds of nickel alloys were prepared and the temperature coefficient of electrical resistance was researched. The influences of nickel constituent and heat treatment on resistance were also studied. The nickel resist-ance wire prepared had excellent stability and special temperature coefficient of electrical resistance.
