摘要
日本国家计量研究所(NMIJ)研制了一台2n自重式力标准机(DWM)。对DWM的力传感器和重量接收器的改进提高了旋转位置变化的测量再现性。两个改进的小容量力传感器，额定容量为1和2n，可根据国际标准化组织(ISO) 376进行精确校准。结果表明，在100 mN至1 N和200 mN至2 N的校准范围内，与商用传感器的目录精度相比，不确定度要小得多。通过与50 N DWM的对比，验证了2 N DWM定标能力的有效性。两个DWMs得到的结果在校准的不确定度范围内是一致的。
Evaluation of small-capacity force transducers using a developed 2 N dead-weight type force standard machine
A 2 N dead-weight type force standard machine (DWM) had been developed at the National Metrology Institute of Japan (NMIJ). Modifications of the force transducers and weight receivers of the DWM improved measurement reproducibility with rotational position change. Two modified small-capacity force transducers with rated capacities of 1 and 2 N could be precisely calibrated according to International Organization for Standardization (ISO) 376. The results showed quite smaller uncertainties in the calibration ranges of 100 mN to 1 N and 200 mN to 2 N than the catalogue accuracies of commercial transducers. The validity of the calibration capability of the 2 N DWM was confirmed by comparing it with a 50 N DWM. The results obtained by two DWMs coincided within the uncertainties of calibration.
