WebOct 8, 2024 · The U.S. Department of Energy's Office of Scientific and Technical Information WebAn important advantage of an eroding thermocouple is the fact that a damaged junction can be remade very easily. The installation of a thermocouple in a surface exchanging heat disturbs the temperature field inside a wall. The effect of this disturbance is the least when heat properties of the wall and thermocouple materials are similar. This
WebThe Surface Eroding Thermocouple (SETC) is a novel ther-mal diagnostic, which was first introduced in a fusion plasma environment for characterizing the heat flux footprint in Alctor C-Mod [10]. The measuring junction of SETC is formed by two dissimilar metal ribbons isolated by a thin isolation layer WebJan 1, 2024 · An eroding thermocouple was embedded in the gear. It was originally developed by the authors where a thin Parylene film was employed as an insulator separating two poles [12, 13]. The thermocouple was inserted in a hole with 0.4 mm diameter on a gear flank drilled by electrical discharge machining. The data logger was …
