Abstract

La presente se refiere a un método para medir la temperatura de un bano de metal fundido por medio de una fibra optica que está circundada por una cubierta. La fibra optica es sumergida en el bano en estado fundido y la radiacion absorbida por la fibra optica en el bano en estado fundido es alimentada a un detector, en el cual la fibra optica es calentada cuando se sumerge en el bano en estado fundido. La curva de calentamiento de la fibra optica tiene al menos un punto P(t0, T0), en el cual el incremento deltaT1 en la temperatura T de la fibra optica a través de un tiempo deltat durante un primer intervalo de tiempo t0deltat hasta la temperatura T0 es menor que el incremento deltaT2 en la temperatura de la fibra optica a través del tiempo deltat durante un segundo intervalo de tiempo t0+deltat inmediatamente subsiguiente.
