A zirconia single-crystal fibre-optic sensor for contact measurement of temperatures above 2000\0\C

A radiation-based zirconia single-crystal fibre-optic temperature sensor has been developed. This novel sensor can be operated up to 2300\0\C. A 60 mm long and 0.45 mm thick yttria-stabilized zirconia single-crystal fibre, coated at one end with a layer of BeO ceramic, is used to generate and transm...

Summary:A radiation-based zirconia single-crystal fibre-optic temperature sensor has been developed. This novel sensor can be operated up to 2300\0\C. A 60 mm long and 0.45 mm thick yttria-stabilized zirconia single-crystal fibre, coated at one end with a layer of BeO ceramic, is used to generate and transmit radiation signals at high temperature. Another 520 mm long and 0.80 mm thick sapphire fibre is used as a sub-high temperature waveguide. Experimental results from 1200\0\C to 2300\0\C demonstrate that the sensor is very promising for applications beyond 2000\0\C. (Original abstract - amended)
