A light-guide transducer has been developed and experimental 
investigations of the distinctive features of radiant heat exchange 
between the smelting zone and the wall of the crystallizer of an 
electroslag-remelting unit have been carried out. A relation making 
it possible to determine the slag or metal temperature has been 
obtained. A method of measurement and the structure of a sensor 
of liquid-metal level have been developed; its operating 
characteristics have been investigated.
