<p><P>PROBLEM TO BE SOLVED: To solve a problem that a proper protection to optical fiber is impossible after a short time, because of a rapid melting of protective covering in measuring apparatuses using a conventional optical fiber. <P>SOLUTION: This measuring apparatus of the temperature of molten metal measurement system supports an optical fiber connected with a measuring instrument directly or indirectly by a supporter and while the dipping end of optical fiber is guided through a consumptive main body wasting away within molten metal, the consumptive main body has a depletion rate equal to or larger than a destroying rate of the dipping end of optical fiber but less than 10 cm/min. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
