  • Method and measuring instrument for measurement of the casting level in a mould
    Patent number: 11731190
    Abstract: A method for measurement of the casting level in a mould incudes the steps of: a) impressing a temporal current profile into a transmitting coil that is arranged at the mould, during a measuring time interval; b) measuring a temporal signal profile resulting in a receiving coil during the measuring time interval, wherein the receiving coil is coupled inductively to the transmitting coil; c) selecting a time window within the measuring time interval, and d) evaluating the measured temporal signal profile within the selected time window to determine the casting level.
    Type: Grant

  • Method for detecting a level of a melt, method for detecting a thickness of a casting powder, detector and detector system
    Patent number: 10768036
    Abstract: A method detects a level of a melt contained by an oscillating mold. The method includes a) sensing radiation interacted with the melt and generating from the sensed radiation radiation signals, such that the generated radiation signals are varied by the mold oscillation, b) determining a radiation signal variation of the generated radiation signals, c) determining an oscillation deflection variation of the oscillating mold, and d) determining from the determined oscillation deflection variation and the determined radiation signal variation, the level of the melt.
