  • Thermo-couple with linear drift for liquid steel
    Patent number: 5675118
    Abstract: Continuous temperature measurement for liquid steel has in the past been made only with a thermocouple with exponential drift. With a diameter ratio of about 2 between metal and ceramic wells and with exceptionally thin electrical insulation, a lower, calculable linear drift can be achieved thus giving a substantially longer service life.
