High electrical conductivity, accuracy and cost-effective
RTD cable with copper conductors
Mineral insulated RTD cable with copper conductors is a common choice for temperature measurements up to 400°C. Copper conductors have a very stable resistance vs temperature relation. Furthermore, the material is economically priced.
