- Abstract:
- Since November 2008, PTB's force scale has been complemented in the range from 2 to 5 MN by a further force standard machine. This automatically working 5 MN Force Standard Machine (FSM) utilizes the hydraulic amplification of a 50 kN mass stack and enables low uncertainties of smaller than 0.01% by using innovative methods for the control principle and the link-up of the force standard. In the paper, the constructional design of the machine, the control and the innovative link-up procedure will be published. Supplementary to this, results from comparison measurements of the machine with PTB's 2 and 16.5 MN FSM are presented.
