Title: Thermocouples with two tabs spaced apart along a transverse axis and methods

Abstract: Methods for determining a temperature of a portion of an electrically conductive substrate are provided wherein the substrate is heated by applying an electrical current flow through the substrate. The method for determining the temperature employs a thermocouple including a first tab element and a second tab element that are spaced apart from one another along an axis transverse to a direction of the current flow. In another example, an apparatus includes an electrically conductive substrate and a direct heating apparatus configured to heat the substrate with an electrical current flow through the substrate. The apparatus includes first and second coupling positions of a thermocouple that are spaced apart from one another along an axis transverse to a direction of the current flow.
