1. A system for obtaining real time measurements of a variable of a molten metal bath where the magnitude of the variable is measured by the immersion into the molten metal of a primary element for detecting said variable, and said primary element is an expendable device which plugs into the end of a lance for immersion into the molten metal and unplugs from the lance after the measurement is made and the lance is withdrawn from the molten metal, comprisinga data transmitting assembly connected to receive the output of said primary element and operable to convert that output to a digital form and to transmit a radio signal indicative of the magnitude of said digital form only when the magnitude of said variable is within a predetermined range, which indicates that the primary element is plugged into said lance and that it is providing a valid reading;

  • a data receiving assembly operable to receive said transmitted radio signal; and

    a display device responsive to the output of said data receiving assembly to display the magnitude of said variable.
