| Zusammenfassung | Keeping in mind the need to have lower measurement uncertainties associated with force standard machines (FSM) to calibrate force instruments, the National Physical Laboratory of India (NPL(I)) has recently installed a new 1 MN force standard machine. The force is generated by dead weights up to 100 kN and a lever multiplication of dead weights up to 1000 kN. The machine has certain novel design features, which result in the lowest uncertainties. This paper contains a description of the functional principles and new design aspects of this machine. The uncertainties of measurements are calculated for both the lever and the deadweight side according to the new EURAMET calibration guide. The results of a comparison with the Physikalisch-Technische Bundesanstalt (PTB) are presented here, too. |
