Excerpt from Laboratory Notes on Heat Measurements
The Le Chatelier thermo-electric pyrometer is based upon the increasing electromotive force which exists at a junction of two metals as the temperature rises. If we have a pair of dissimilar metallic wires, their junction becomes the seat of an electromotive force, and if they be joined at both ends, a current will flow through them as the result of the difference between the electromotive forces. At the two ends of the wires. In general, this current is dependent upon the difference in temperature, though not directly proportional to it. In order to use this phenomena as a basis for a pyrometer, since there is no known relation existing directly between temperature and electromotive force in such a cir cuit, we must expose the 'junction to known temperatures and note the current flowing, and in this way calibrate. It is usually customary to observe, not the electromotive force, but the current, keeping the total resistance of the circuit constant in order that this may be allowable.
