铂铑_(10)—铂热电偶是一种很重要的温度测量元件,它具有测量范围宽、使用方便、精度高等优点,故广泛地用于工业、农业、国防和科研等的各部门。 1968年四家美国工厂、三家英国工厂提供丝材,而由美国标准局(NBS)、英国物理研究所(NPL)、加拿大国家研究院(NRC)三家对铂铑_(10)—铂热电偶进行了分度研究。由NBS负责材料的收集和热电偶的装配,然后将制成的热电偶送一半给NRC。由NBS和NRC对热电偶进行定点分度,并从0℃—金点进行比较分度。从NBS和NRC中挑选的热电偶,由NPL
Platinum and rhodium _ (10) - platinum thermocouple is a very important temperature measurement element, it has wide measurement range, easy to use, high accuracy, it is widely used in various sectors of industry, agriculture, national defense and scientific research. In 1968, four American factories and three British factories supplied wire materials, while three American counterparts from the National Bureau of Standards (NBS), the British Institute of Physics (NPL) and the National Research Council of Canada (NRC) An indexing study was conducted. NBS is responsible for material collection and thermocouple assembly, and then half the resulting thermocouple to the NRC. Thermocouples are indexed by NBS and NRC at a fixed point and compared from 0 ° C to the gold point. Thermocouples selected from NBS and NRC, by NPL
