热电偶的中间金属材料定则表明:在热电偶回路中接入第三种金属材料,只要这第三种金属材料两端温度相同,则热电偶所产生的热电势保持不变,即不受第三种金属材料接入的影响。根据这个定则,在进行温度测量时,可将两根热电偶丝分别焊接在待测金属的有关部位上。这种测温方法,是以待
The thermocouple’s intermediate metal rule states that the thermocouple generates a thermoelectric potential that is constant as long as the third metal material has the same temperature across the thermocouple loop The third metal material access impact. According to this rule, during the temperature measurement, two thermocouple wires can be respectively welded on the relevant parts of the metal under test. This temperature measurement method is waiting
