Abstract
PURPOSE:To perform high-accuracy force measurement by constituting a secondary vibration system which has a lower natural oscillation frequency than the basic frequency of an arcuate or tuning-fork vibrator by using a weight and a spring, and coupling it additionally with both sides or one side of the vibrator. CONSTITUTION:Vibration mechanisms 8 are formed integrally at both ends of the vibrator 4. The mechanism 8 is the secondary vibration system which has the longitudinal natural vibration frequency determined by the spring coefficient of the ring spring 9 and the mass of the weight 10 including bar 11. Then when static force F to be measured is applied to the mechanism 8, the spring 9 expands slightly, but the presence of the weight 10 is irrelevant to the transmission for the force F to be measured and a measurement result has no difference regardless of whether or not there is the mechanism 8. Further, the natural oscillation frequency of the mechanisms 8 can be set much smaller than the basic frequency of the of the vibrator 4 to the outside is reduce and the influence of external vibration is also small. Thus, the high-accuracy measurement is performed.
