The automatic belt weigh-feeders are used in any industrial process requiring a constant afflux of material (granular or powder) with a constant mass flow. The belt conveyor includes a weighing system for the material on the feeder-belt.

The equipment allows communication with a computer or PLC and it is produced by Mitsubishi Electric, characterized by the following performances:

  • Special flexibility in the configuration of any application,
  • Easy integration in the industrial communication networks (Ethernet, Profibus, DeviceNet, RS 485, CC-Link, Can Open),
  • Initial low cost of the equipment,
  • Low maintenance cost, the spare parts being produced in large series,
  • Compatibility with CE industrial standards, guaranteed through certification.
