Primary Sinusoidal Calibration of Force Transducers up to 2 Kilohertz



Akobuije D. Chijioke, Nicholas A. Vlajic


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 show an example calibration of a strain-gauge based force transducer to better than 1 % expanded uncertainty (k = 2) over the calibration frequency range. The current dominant source of uncertainty in the system is angular motion of the calibration assembly.
