钨铼热电偶是在20世纪60至70年代得以发展的最成功的难熔金属热电偶。由于铂铑热电偶价格上涨,以及宇航和核工业领域的需求,进一步促进了钨铼热电偶的开发与应用。热电极丝长度的选择是由安装条件,主要是由插入深度决定的,热电偶丝的直径与长度,虽不影响热电动势的大小,但是,它却 Tungsten-rhenium thermocouples were the most successful refractory metal thermocouples that developed in the 1960s and 1970s. Due to rising prices of platinum rhodium thermocouples, as well as the needs of the aerospace and nuclear industries, the development and application of tungsten-rhenium thermocouples are further promoted. Thermocouple wire length is selected by the installation conditions, mainly by the depth of the decision, the diameter and length of the thermocouple wire, though does not affect the size of the thermoelectric force, but it is
