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.

Only high quality RTD Constantan cable
- By Japanese manufacturer Okazaki, made with Japanese and European sourced materials
- Supplied with a material 3.1 certificate
- Excellent temperature stability and low thermal EMF
- Good corrosion resistance, and mechanical robustness
- Available in coiled form, with an option for straight lengths, which may retain a natural curvature.
- The wall thickness is generally no less than 10% of the cable diameter.
- Can be bent around a mandrel with a radius twice the sheath diameter without compromising sheath integrity or insulation resistance.
- The sheath is compatible with welding, brazing, and soldering, preserving insulation resistance when standard care is applied for the metal type and thickness.
