The material of conductor is not identical, and there are biggish differences for thermal expansion coefficient, and under conditions of high temperature, the two can occur in various degree
Expansion, cause measurement end temperature element pin (or conducting wire of cold end) and middle conductor contact area reduce, or even hair
Raw hanging, i.e., measurement end (or cold end) is disconnected with pitman, along with the generation of high-frequency vibration, measurement end (or cold end) and
Contacted when pitman, when and disconnect, can not normal use, that is, lose using function, while the measurement end thermometric of different materials
After pin (or conducting wire of cold end) and the middle conductor assembling of element, under high temperature and high-frequency vibration, stress can occur for the two not
Balance, with the extension of use time, unequal power distribution phenomenon gradually aggravates, and eventually leads to the pin of measurement end temperature element
