Abstract
A heater system includes a heater and a controller. The heater 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, and a resistive heating element having two ends and made of a material that is different from the first and second conductive material of the first and second power pins. The resistive heating element forms a first junction with one end of the first power pin and a second junction at its other and with the second power pin. The controller is in communication with the power pins for measuring changes in voltage at the first and second junctions to determine an average temperature of the heater based on the changes in voltage.
