This article presents a study carried out on a 2 kN·m torque transducer at the Central Office of Measures (GUM) and the Physikalisch-Technische Bundesanstalt (PTB). The weighted least squares method was used to generate the linear regression equations for this torque transducer. The Monte Carlo method and the law of uncertainty propagation were used to calculate the expanded uncertainty. In addition, a creep study was carried out at eight measurement points ranging from 200 N·m to 2000 N·m. The investigations showed that the highest readings of the torque transducer, expressed in electrical units as mV/V, occur within the initial few seconds of the test after the removal of the maximum reference torque.

在 GUM 和 PTB 测试的 2 kN·m 扭矩传感器研究，包括蠕变行为

本文介绍了中央测量办公室 (GUM) 和德国联邦物理技术局 (PTB) 对 2 kN·m 扭矩传感器进行的研究。加权最小二乘法用于生成该扭矩传感器的线性回归方程。采用蒙特卡罗方法和不确定性传播定律计算扩展不确定性。此外，还在 200 N·m 至 2000 N·m 范围内的 8 个测量点进行了蠕变研究。调查显示，扭矩传感器的最高读数（以电气单位 mV/V 表示）出现在最大参考扭矩移除后测试的最初几秒钟内。
