镍铬硅—镍硅(N 型)热电偶丝是一种新型的镍基合金测温材料,主要用于工业生产和科学研究过程中的温度测量和控制。七十年代由澳大利亚国防部材料研究所和美国国家标准局联合研制成功。一九八五年九月国际电工委员会(IEC)65B 分会发布97号文件,推荐为 IEC 标准型号热电偶,并把它补充进IEC_(584-1)分度和 IEC_(584-2)允差标准中。我们研制的 N 型热电偶丝等效采用 IEC 标准,并在企业标准中增加头尾热电动势均匀性和热电动势长期稳定性等技术指标,产品性能达
Nickel-chromium-silicon-nickel (N-type) thermocouple wire is a new nickel-based alloy temperature measurement material, mainly used in industrial production and scientific research process temperature measurement and control. Seventies by the Australian Department of Defense Materials Institute and the United States National Bureau of Standards jointly developed. Sept. 1985 IEC IEC Sub-Committee No. 65B Issue No. 97, recommended as IEC standard thermocouple and added to IEC_ (584-1) Graduation and IEC_ (584-2) Tolerance Standard. We developed the N-type thermocouple wire equivalent to the use of IEC standards, and in the corporate standards to increase the head and tail thermal EMF and thermal EMF long-term stability and other technical indicators, product performance
