PCT No. PCT/EP91/00958 Sec. 371 Date Jan. 22, 1993 Sec. 102(e) Date Jan. 22, 1993 PCT Filed May 22, 1991 PCT Pub. No. WO91/18269 PCT Pub. Date Nov. 28, 1991Continuous 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.
