- •
The relationship between instrument sensitivity and pivot's stiffness is revealed.
- •
Cross-spring pivot with quasi-constant rotational stiffness is designed.
- •
The sensitivity of the instrument is almost the same in the whole payload range.
- •
Cross-spring pivot has good prospects in unbalance moment measurement.
