Balancing Machine Sensitivity Calculator
Calculate minimum detectable unbalance (Umin) and achievable balance grade for soft or hard bearing balancing machines per ISO 21940-21 (formerly ISO 2953).
Results
Minimum Detectable Unbalance
Ang pinakamaliit na matutuklas na unbalance (Umin) ng isang balancing machine ay nakasalalay sa sensitivity ng sensor, electronic noise floor, at display resolution:
Achievable Balance Grade
Kung saan ang ω ay ang angular velocity sa service speed (hindi ang bilis ng pagbabalanse).
Praktikal na panuntunan: Umin should be well below the permissible residual unbalance (Uper) — typically no more than about 10% — so that measurement uncertainty does not dominate the result. Balancing machines themselves are described and evaluated per ISO 21940-21 (formerly ISO 2953), which defines the minimum achievable residual unbalance (Umar) and unbalance reduction ratio (URR) tests.
