The DE-CONscrew control system is used to support the operation of loss-in-weight feeders for the dosing of bulk materials and powders by dosing screws. Due to continuous performance determination and evaluation, automatic performance adjustment can be made at any time.


  • Controls the setpoint-precise dosing according to the „Loss in Weight“ principle into a continuous process
  • Supports the gravimetric and volumetric operation of differential weighers when dosing bulk materials and powders by dosing screws
  • Highly accurate dosing due to adaptive control
  • Optimized refill handling
  • Integrated control of a conveyor system (option)
  • Automatic scale calibration
  • Speed monitoring of the discharge unit (digital / analog)
  • Continuous performance determination and analysis for automatic performance adjustment in startup and shutdown mode
  • Single and group operation
  • Time-based throughput counters
  • Control of additional components for product activation (screws, beaters) and dust prevention (filters, extractors)
