Abstract
The present disclosure is directed toward a heater that includes a resistive heating element, a first power pin, and a second power pin. The first power pin forms a first junction with a first end of the resistive heating element, and the second power pin forms a second junction with the second end of the resistive heating element. The second power pin includes a first lead wire and a second lead wire. The first lead wire forms the second junction with the second end of the resistive heating element and defines a first conductive material. The second lead wire forms a primary sensing junction with the first lead wire at a first reference area, and defines a second conductive material different from the first conductive material to measure a temperature at the first reference area based on a voltage change created by the primary sensing junction.
