Abstract

A bubbler device and method of its operation are disclosed. The bubbler device includes a bubbler tube that provides bubbles to a molten material in a furnace; a protective layer disposed on the bubbler tube; and a wire that is electrically coupled to the protective layer. The wire extends through the bore, and the protective layer and the wire partially form an electrical circuit for measuring integrity of the bubbler device based on at least one of conductivity or resistance in the electrical circuit. Sometimes, an inner protective material may be disposed on an inside surface of the tube and coupled to the protective layer, and the wire can be coupled to the inner protective material or multiple wires may be used. The use of dissimilar materials in these components may be used to form a thermocouple junction to measure the temperature of the molten material in a furnace.
