High speed dynamic weighing of unit loads
In order to save time and also to reduce the weighing error it is recommended to read the signal at a time that corresponds to the point of intersection between the curve of dynamic deflection and the line of static equilibrium of the weighing device.
The formulas that are derived give the theoretical calculation of this time for transient process whenω0>λ,ω0=λ; they also determine the error of weighing.
Calculations show that when the mass measured is within acceptance limits corresponding to 3–5% of the measured mass, the dynamic deflection curve intersects the static equilibrium line at practically one and the same instant of time. The error of measurement is least during the transient process whenω0>λ.
