GLASS CONDUCTIVITY AND TEMPERATURE PROBE

摘要

A device for measuring the conductivity and/or temperature of glass in molten state. A probe including a hollow elongated member of nonconductive material has a pair of spaced external bands of conductive material near one end with an internal lead from each band extending to the other end of the elongated member. The leads are connected with power input means and an AC to DC converter, the latter of which is connected with a voltage readout to supply direct voltages thereto which are indicative of the conductivity of the molten glass between the bands on the probe. In addition, a thermocouple is positioned within the elongated member at the end with the bands thereon with leads therefrom being connected with a temperature readout that is externally positioned with respect to the probe.
