The electronic belt-weighers produced by Automatica SA are designed for the high precision weighing of the materials conveyed on fixed or variable speed conveyor belts.

The operating principle is based on the dynamic weighing with software fragmented and indexed belt that offers the highest achievable precision in industrial applications, in difficult operating conditions.

The weighing is not influenced by the variations in thickness, width or density of the conveyor belt.


The belt-weighers are equipped with operator consoles that insure the visualization of the operating parameters and the entering of the calibration and configuration parameters.

For the essential parameters of the belt-weigher (debit, specific load and belt speed) evolution trends are posted that are very useful in supervising the process evolution.
