Excellent temperature stability and low thermal EMF
RTD cable with constantan conductors
Mineral insulated RTD cable with constantan conductors is a perfect choice for temperature measurements up to 650°C. Constantan conductors have a very stable resistance for a wide temperature range since it is a copper-nickel alloy.
