*Available with a desired wire diameter
Temperature control sensors used in steel, glass, electrical, semiconductor, and chemical industries
As the negative electrode of pure platinum used in type R thermocouples has the disadvantage of easily fracturing at high temperatures, zirconium oxide was dispersed in platinum for the first time in the world, which creep strength of negative electrode at high temperature by ten-time of conventional ones.
Thermoelectromotive force in type R thermocouples
Initial stress and creep fracture time
This exhibits the same thermoelectromotive characteristics as the negative electrode of pure platinum currently in use, and can therefore be replaced conventional lines.
* The standard wire diameter is φ0.5, with class 2 precision.
For <φ0.5, the maximum length is 3m.
If you would like a different wire diameter or class 1 materials, please inquire separately.
