Sistema y metodo para la medicion del nivel de llenado vertical de un material conductor de la electricidad en un volumen de contencion de un recipiente metalurgico, donde este se define mediante una carcasa metalica exterior que rodea el volumen de contencion, dicho sistema comprende un hilo conductor transmisor y un hilo conductor receptor, donde los hilos conductores se disponen en el interior de la carcasa mecanica

摘要

The vertical filling level of electrically conductive material in a cavity of a metallurgical vessel is measured by a system including a transmitting conductor for generating an electromagnetic field when connected to an alternating power source, and a receiving conductor which senses the electromagnetic field for generation of an output signal. The conductors are arranged inside a metal casing of the vessel to co-extend with a mutual spacing defining a spacing area that faces the cavity and extends along the periphery in an essentially closed loop. The mutual spacing is selected such that changes in the output signal is dominated by changes to the electromagnetic field caused by local changes in the amount of the conductive material adjacent the spacing. Part of the spacing area defines a vertical measurement region slanted along the periphery so as to diverge from the horizontal and vertical directions of the vessel.
