Paper Abstract

The quality of the steel, among others, depends on the temperature profile during the last cooling process. Because of that, the capability of real-time temperature measurements at several points of the steel bars during the aforementioned production process is highly desirable in order to build a smart structure. To measure temperatures in the range of 800 - 1300 degrees centigrade, the sensor system proposed, is doted of new fiber optic transducers. They are based on the measurement of the optical radiation generated by the hot steel bars through a geometric cavity which is properly designed and fabricated to maximize its accuracy.
