UNCERTAINTY EVALUATION OF SINUSOIDAL FORCE MEASUREMENT

Christian Schlegel, Gabriela Kiekenap, Rolf Kumme
Abstract:
Periodical force measurement is used for the primary calibration of force transducers. This abstract describes models for an uncertainty determination of the sensitivity, which is the main measurand. Influences like the mechanical coupling of test masses as well as their rocking during a measurement are the dominating contributions to the uncertainty of measurement. The achievable uncertainties will be demonstrated on the basis of intercomparison periodical force measurements between CEM and PTB as well as the comparison between standard GUM and Monte Carlo based uncertainty evaluation.
