Abstract
A thermocouple assembly may feature a plurality of temperature sensors formed by thermocouple junctions. The sensors may be disposed within an inner diameter of the tubular element and sealed within the tubular element by thermally conductive material. An air gap may be defined by the thermally conductive material and the interior diameter of the tubular element between each pair of adjacent temperature sensors to improve thermal isolation.
