- Abstract:
- This paper present the completion and the measurement uncertainty budget of a multi-component measuring facility. The new facility is part of the 1 MN force standard machine of the PTB. It enables the simultaneous generation of a torque in the range from 20 N·m to 2 kN·m in addition to axial forces 20 kN to 1 MN. This allows the characterization of measuring systems which require combined loads of axial forces Fz and torques Mz like friction coefficient sensors. The aim is a measurement uncertainty of (k = 2) for Mz < 0.01% and Fz < 0.002%. The physical model yields to extended measurement uncertainties (k = 2) for 20 N·m of 5.9 · 10-5 and for the maximum load step 2000 N·m 4.2 · 10-5.
