Physikalisch-Technische Bundesanstalt的1 MN力标准机中的扭矩产生测量装置允许产生组合载荷条件。轴向载荷的测量范围从20 kN到1 MN，扭矩的测量范围从20 N·m到2 kN·m。该测量设备在世界上是独一无二的，提供了专门针对多组分传感器的信号串扰来表征其特性的机会。轴向力的扩展相对测量不确定度(k = 2)为2·10−5。下面将描述扭矩测量装置的技术细节和从建模到测量不确定度预算的计量特性。该模型提供了扩展的相对测量不确定度(k = 2) <； 3.9·10−4。
A torque-generating measuring device in the 1 MN force standard machine of Physikalisch-Technische Bundesanstalt allows combined load conditions to be generated. Superposition is possible in measuring ranges from 20 kN to 1 MN for axial load and from 20 N · m to 2 kN · m for torque. The measurement facility is unique in the world and offers the opportunity to characterize multi-component sensors specifically with regard to their signal crosstalk. The expanded relative measurement uncertainty (k = 2) of the axial force is 2 · 10−5. In the following, the technical details of the torque measuring device and the metrological characterization from the modelling to the measurement uncertainty budget will be described. The model provides an expanded relative measurement uncertainty (k = 2) < 3.9 · 10−4. The results of comparison measurements will be discussed.
