Measuring device for measurement of parameters in molten masses

摘要

MEASURING DEVICE FOR MEASUREMENT OF PARAMETERS IN MOLTEN MASSES The invention relates to a measuring device for measurement of parameters in molten masses, in particular for measuring the temperature, in particular in molten metal or molten cryolite masses having a melting point above 500 *C, having an optical fibre (6) for taking up radiation from the molten mass and having a cable reel (8) that com 10 prises an external circumference for taking up the optical fibre and an internal space that is surrounded by the external circumference. A distributor (18) and a mode filter (21) for the optical fibre (6) are arranged in the internal space. 10i8 Fig. 1
