Construction of a standard force machine for the range of 100 μN–200 mN

A new force standard machine (FSM) for the range of 100 μN–100 mN has been developed [1]. The machine is based on the comparison of a force transducer with the indication of an electromagnetic compensated balance (ECB). Construction details as well as first measurements will be presented. To guarantee traceability to the established deadweight force machines, the new facility was compared with the PTB 200 N FSM.

► Standard force machine for forces below 1 N.
► Fully automated micromechanical design.
► Nanometer precise positioning devices integrated.
► Traceability to standard deadweight machines approved.
