New method for measuring the high temperature of molten steel in ladle by fiber optic sensor

This paper presents a kind of low cost, one-off fiber optic temperature sensor that has been used to replace the expensive Pt-Rh thermocouple to measure the temperature of molten steel. The detail design scheme of the probe of the fiber optic sensor, the structure of the secondary instrument and the calculating method has been studied.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.
