Abstract

Un método, puesto en práctica por un dispositivo informático controlado por un software y/o por un hardware dedicado, que está diseñado para sondear un material objetivo eléctricamente conductor (M), por ejemplo, metal fundido o material semiconductor, en una vasija metalúrgica (1). El método consiste, en particular, en adquirir una señal de medida desde un sensor (4), que está insertado en el material objetivo (M), durante un desplazamiento relativo entre el material objetivo eléctricamente conductor (M) y el sensor (4), siendo la señal de medida indicativa de la conductividad eléctrica en la proximidad del sensor (4) La señal de medida se genera para representar cambios momentáneos en un campo electromagnético alrededor del sensor (4), en donde se crea activando al menos una bobina (82; 92) en el sensor (4). A partir de la señal de medida, se genera un perfil de señal para indicar la conductividad eléctrica como una función del movimiento relativo. El método permite sondear la distribución interna del material objetivo (M) dentro de la vasija (1) sin importar el nivel de detalle. El perfil de señal puede analizarse para proporcionar información sobre zonas/capas (S, M1, M2) que difieren, por ejemplo, por la composición de materia, el grado de fusión o el grado de mezcla.
