Sinusoidal Force Standard

The NIST 2 kHz force standard provides SI-traceable dynamic force excitation at frequencies up to 2 kHz with expanded uncertainties in the 1 % to 2 % range for sinusoidal forces.  It provides a primary standard by which force measuring instruments may be tested, with dynamic force amplitudes up to 2 kN. The uncertainty of the applied force in a given test depends on a number of factors, including the device under test. Sinusoidal operation at frequencies up to 4 kHz is possible.
