A system for determining a side of an electrical circuit exposed to a high temperature includes a printed circuit board having at least two outer edges and first and second board stiffeners of a first material disposed along the outer edges. The system also includes a control unit and a plurality of traces formed of a material that is different than the first material and has a second Seebeck coefficient. The control unit determines whether the first edge or second edge is closer to the high temperature based on a voltage differential between a trace connecting it to the first end of the first board stiffener and a trace connecting to the first end of the second board stiffener.

In one aspect, a temperature sensing assembly for measuring temperature of a surface of a structure includes a thermocouple device and a docking device. The thermocouple device includes a temperature sensing junction point disposed within an elongate sheath to measure the temperature of the surface of the structure at a desired location.
