以金铁丝为一极的热电偶,近来在测量低温温区的温度量值很受人们的欢迎。因为在这一温区铜-康锔热电偶、镍铬-镍硅热电偶的测温灵敏度—热电势率(塞贝克字数)已经很小了,失去了使用的价值。而金铁特别是和镍铬丝相配时,却完全满足了几乎从0～273开的整个负温区的测温灵敏度的 Thermocouples with gold wire as one pole have recently gained popularity in measuring the temperature in low-temperature regions. Because in this temperature zone copper - Kang 锔 thermocouple, nickel chrome - nickel silicon thermocouple temperature sensitivity - thermoelectric power (Seek words) has been very small, lost the value of use. The iron and iron, especially with nickel chrome wire match, but fully meet almost from 0 to 273 open the negative temperature sensitivity of the entire area
