Abstract
919,879. Measuring temperature electrically. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 23, 1959 [Nov. 26, 1958], No. 39656/59. Class 40 (1). A method of measuring the temperature of molten metal in a bath using a thermo-couple comprising two separated wires of dissimilar metals enclosed within a metal envelope, with the interposition of inorganic insulating material between one pair of ends of the wires and between these ends and the wall of the envelope, the metal envelope having a melting pointlower than that of the molten metal, comprises dipping the end of the thermo-couple in the molten metal in the bath so that the envelope melts and the molten metal in the bath establishes an electrical connection between the ends of the wires. The inorganic insulating material can be MgO or Hl 2 O 3 , the metal of the envelope can be nickel, the wires can be of platinum/ platinum-rhodium and the molten metal can be steel. The metal envelope containing the wires is passed through any slag on top of the bath into the molten metal. After use the ends of the wires can be cut off and the metal obtained therefrom.
