Corrosion-resistant, mechanically robust and providing long-term stability
Mineral insulated RTD cable with nickel conductors
Mineral insulated RTD cable with nickel conductors is used for temperature measurement up to 600°C. Nickel conductors have a higher annealing temperature, making them suitable for high-temperature applications. Kamet supplies nickel conductor MI RTD cable manufactured by Okazaki in various sheath materials, diameters and conductor configurations.

Why use nickel conductors in MI RTD cable?
Nickel conductors are suitable for higher-temperature RTD cable applications because of their higher annealing temperature. Kamet’s nickel conductor MI RTD cable is used for temperature measurements up to 600°C and is available in mechanically robust and corrosion-resistant configurations for demanding environments.

Specifications of Okazaki nickel conductor MI RTD cable
- By Japanese manufacturer Okazaki, made with Japanese and European sourced materials
- Supplied with a material 3.1 certificate
- Suitable for high-temperature applications
- Corrosion-resistant and mechanically robust applications
- Providing long-term stability and reliability in harsh environments
- Provided in coiled form but can be ordered as straight lengths, which may show a slight curvature.
- The wall thickness is typically a minimum of 10% of the cable’s diameter.
- Flexible enough to bend around a mandrel with a radius at least twice the sheath diameter, maintaining sheath integrity and insulation resistance.
- The sheath allows for welding, brazing, or soldering without affecting insulation resistance, provided standard precautions are observed for the specific metals and thicknesses.
