小型固定点装置温坪性能研究

Performance Study of Temperature Plateau with Mini Fixed-piont Furnaces

给出了锡点、锌点和铝点三个小型固定点装置的垂直温场调节方法和温坪复现方法,并对调节前后的温屏曲线进行了比较。该小型固定点装置温坪曲线特性满足现有国家计量检定规程对于检定二等标准铂电阻温度计和精密级铂电阻温度计的要求。

This paper introduces the methods of adjusting vertical temperature field and the realization methods of temperature plateau with the mini fixed-point furnaces of Tin, Zinc and Aluminum points. Then it gives the comparison of the temperature plateau curves . The performance of temperature plateau curves about these mini fixed-point furnaces can be satisfied to the national calibration specification. It can also be satisfied to the index of calibrating the class II standard and precise grade SPRT.
