Abstract

Results of an evaluation of a single crystalline sapphire fiber with a Cr^3- doped (ruby) tip for thermometric use up to 1500°C are reported. The study shows that the single crystal probe is able to operate continuously at temperatures up to 1400°C. and can reliably cover a wide temperature measurement range from -50°C to 1400°C.
