Abstract
A thermocouple is disclosed for the continuous measurement of the temperature of a molten phase, which thermocouple comprises two cermet elements of dissimilar metals in which the thermoelectric circuit is closed by the medium, the temperature of which is being measured. The use of dissimilar cermet elements as opposed to conventional metallic wires imparts to the thermocouple sensor a superior resistance to high temperature, corrosive environments which allows it to be used for extended periods of time and for varied applications. A method of using the thermocouple is also disclosed.
