  • Device for detecting the surface level of molten metal in a mold
    Patent number: 4112759
    Abstract: A device for detecting the surface level of molten metal in a mold, in which a thermo-sensitive magnetic element the relative magnetic permeability of which varies depending upon temperature is provided on an outer wall surface of the mold, and a coil connected to an A. C. power supply is mounted so as to leave a gap between the thermo-sensitive magnetic element and the coil, so that variation in electromagnetic coupling between the coil and the thermo-sensitive magnetic element due to temperature increase of the mold according to the rise of molten metal level can be detected.
