Abstract
A heater is provided that includes a first power pin made of a first conductive material, a second power pin made of a second conductive material that is dissimilar from the first conductive material of the first power pin, and a resistive heating element having two ends and made of a material that is different from the first and second conductive materials of the first and second power pins. The resistive heating element forms a first junction at one end with the first power pin and a second junction at its other end with the second power pin, and changes in voltage at the first and second junctions are detected to determine an average temperature of the heater.
