Glass melt temp measurement - by electrical conductivity determination of melt section

摘要

The temp. of glass melts in furnaces is determined by measurement of the electric conductivity of the bath by passage of a low voltage current through it and determining the voltage drop across it. The prefd. voltage current is between 5 and 20 V. Mo or Pt electrodes are used for passing the current into the bath. The method permits continuous monitoring of the melt temp. at various furnace sections.
