| Zusammenfassung | A torque-generating measuring device in the 1 MN force standard machine of PTB 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. |
