    摘要： The invention is related to a method and apparatus for measuring the temperature of a melt 52, particularly of a molten metal, with an optical fiber 10, whereby the optical fiber is fed into the melt through a disposable guiding tube 40 and whereby the optical fiber and an immersion end 50 of the disposable guiding tube are immersed into the melt both having a feeding speed whereby both feeding speeds are independent from each other. The optical fiber 10 is partially arranged in the disposable guiding tube 40, whereby the inner diameter of the disposable guiding tube is bigger than the outer diameter of the optical fiber, whereby an elastic plug 30 is arranged at the second end opposite to the immersion end of the disposable guiding tube, whereby the optical fiber is fed through the elastic plug and whereby the elastic plug reduces the gap between the optical fiber and the disposable guiding tube. The apparatus comprises a fiber coil and a feeding mechanism for feeding the optical fiber and the disposable guiding tube, whereby the feeding mechanism comprises at least two independent feeding motors 25, 45 , one 25 for feeding the optical fiber and one 45 for feeding the disposable guiding tube.

    摘要： The vertical filling level of electrically conductive material in a cavity (3) of a metallurgical vessel is measured by a system comprising a transmitting conductor (5) for generating an electromagnetic field when connected to an alternating power source, and a receiving conductor (6) which is arranged to sense the electromagnetic field for generation of an output signal. The transmitting and receiving conductors (5, 6) are arranged inside a metal casing of the vessel to co-extend with a mutual spacing to define a spacing area (7) that faces the cavity (3) and extends along the periphery of the cavity (3) 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 to the spacing area (7). At least part of the spacing area (7) defines a vertical measurement region in which the spacing area (7) is slanted along the periphery so as to diverge from the horizontal and vertical directions of the vessel. Thereby, the spacing area (7) may be adapted to any shape of the cavity (3) so as to design the system with any desired transfer function, e.g. linear without turning points outside the extent of the vertical measurement region.
