Abstract:
An apparatus for continuously measuring the wear of a wall of a metallurgical vessel, comprised of:a probe including at least two electrically conducting elements which extend generally mutually parallel, wherein one of said conducting elements includes a tubular sheath that contains the other of said conducting elements, and an insulator for mutually insulating said elements from one another within said sheath, wherein said elements have distal end means spaced apart from one another and substantially flush with said insulator of said sheath for contacting metal in said metallurgical vessel when said probe is mounted in said wall of said vessel, anda measurement system connected to proximal ends of the electrically conducting elements for measuring an electrical characteristic of a circuit formed by said elements, which characteristic is dependent upon the length of said elements,wherein the distal end of the probe has a diameter less than 1 mm.
