Abstract:
A surface temperature sensor head comprising:a first layer being a disc of 0.8 mm or less than 0.8 mm in diameter or a square of 0.8 mm or less than 0.8 mm in side and being made of a material of a heat conductivity higher than 100 W/mK; a second layer having crossing tips of a thermocouple and a brazing material; and a third layer being a disc of 0.8 mm or less than 0.8 mm diameter or a square of 0.8 mm or less than 0.8 mm in side and being made of a material of a heat conductivity higher than 100 W/mK; the brazing material unifying the crossing tips, the first layer and the third layer, wherein the crossing tips are positioned in the surface temperature sensor head without extending through either the first layer or the third layer.
