AG446 – Belt Weigher Controller

September 13, 2013

The PR446 controls the feed rate of material from a conveyor belt by adjustment of the belt speed or by adjustment of material feed onto a fixed speed belt. It connects with 1 to 4 load cells fitted to the belt weigher mechanism from which it generates a calibrated weight signal. It also connects with a tacho from which it receives pulses in proportion to belt movement. From these two inputs and from calibrated and control data held in its system memory it calculates the rate of flow of material over the belt.

  • For feedrate & batch quantity control.
  • Provides rate and total information while controlling the flow rate of material into a process.
  • Stored feed rate characteristics.
  • Choice of Kgs/hour or Tonnes/hour feed rate control and display.
  • Both resettable and non-resettable totals.
  • Serial communications and analogue I/O options.
  • Out-of-Tolerance and control limit alarms.
  • Batch quantity feed option.
