    Abstract:
    The quality of the iron steel bars made on the steel production industry, among other, depends on the temperature profile during the cooling and solidifying process. A new multipoint high temperature transducer based on the optical power collected by a group of multimode optical fibers has been developed for measuring the transversal cooling profile. The optic fibers are adequately sheathed by a ceramic mixture in order to achieve its mechanical and thermal protection. Besides in order to use the transducer in pollution environments, the probe is putted inside of a close chamber with a window made with a vitreous ceramic material. The use of silica fiber optic limits the spectral range to analyze, and the measured temperature range. The behavior of the transducer from the angle, the distance and the change of emissivity have been measured, and the transducer has been optimized. The transducer was calibrated in the Photonics Engineering Group laboratory and it was installed in a iron-steel bar manufacturing plant in Spain where it is working high relative humidity and high temperature environment.
