[0038] like Figure 1 The entire device system is assembled as shown. Based on the temperature field measurement requirements, a thermocouple sheath 9 of appropriate length is selected and inserted into the through-hole 4 on the temperature measuring bracket 3. The closed end of the thermocouple sheath 9 is located in the sheath positioning groove 8, and the open end is located outside the temperature measuring bracket 3.
