PRIMARY SINUSOIDAL CALIBRATION OF FORCE TRANSDUCERS UP TO 2 KILOHERTZ

• Abstract:

  We report the implementation of a swept-sine dynamic force calibration system at NIST. This system is designed to perform primary calibration of force transducers at frequencies up to 2 kHz and forces up to 2 kN. We demonstrate the use of this system to measure the dynamic sensitivity of a strain-gauge based force transducer up to 2 kHz. The current dominant source of uncertainty in the system is angular motion of the calibration assembly.
