Control system for gain in weight feeder

The DE-CONbatch scale control system regulates the batch weighing of filling, hopper and platform scales. Due to the self-learning algorithm, a permanent time optimization is achieved.


  • Controls setpoint-accurate weighing according to the „Gain in Weight“ principle
  • Supports recipe-controlled weighing and logging of of up to 16 raw materials
  • Highly accurate weighing due to optimized control sequence
  • Two operating modes available:
    • Coarse/Fine (for maximum speed)
    • Time-optimized (for constant dosing behavior)
  • Suitable for single and/or multi-component weighing
  • System memory for raw material dependent parameters e.g. coarse/fine, tolerances +/-, etc.
  • Self-learning algorithm for time optimization with constant batches (automatic lead correction)
  • Increased process reliability through optional buttons or in conjunction with scanner systems
  • Suitable for weighing bulk materials/raw materials over:
    • Filling scales
    • Platform and bench scales
    • Hopper scales
  • Parameterizable discharge process

We rise to every challenge. We offer custom-fit solutions for dosing, weighing, conveying and refilling of

Bulk solids & Powder and Pastes & Liquids


  • Supports the control of BigBag stations (bag emptying stations, silos, additional discharge stations, additional discharge aids (e.g. knockers), filter cleaning, docking system for dust prevention)
  • In time-critical processes also as „Loss in Weight“ weighing
  • Integrated control of a conveyor system (option)
  • Automatic scale calibration
  • Control of additional components for product activation (screws, beaters) and dust prevention (filters, extractors)
  • Digital filtering of the weight values ( detection digital / analog) for an exact calculation of the feeding capacity
  • High-resolution weight recording via digital/analog load cells
  • Direct connection of load cells (4/6-wire technology)
  • Control of frequency inverter serial/analog
  • Internal alarm buffer
  • Integrated web server for complete configuration and parameterization
  • Can be used in the control cabinet or directly in the plant
  • 4 digital inputs/ and outputs with a number of standard functions (enable, operating contact, external fault, refill process, alarm, etc.) assignable or available for free use


  • Digital/Analog Extensions
  • Operating Options
    • DE-COP 5 single (for single operation of a dosing unit)
    • DE-COP 5 multi (for operating up to 6 dosing units)
    • DE-COP 16 (for operating up to 16 dosing units)
    • Provis (Line software: up to 8 lines á 16 dosing units)
    • AIO-Control (Plant visualization = dosing units + other devices)


  • Numerous interface protocols OnBoard and selectable/ parameterizable via web server
  • Data contents of interface can be adapted flexibly
  • Greatest possible flexibility during project planning, since data contents are available on all interfaces

Supported protocols:

  • Profinet
  • Modbus TCP
  • Ethernet IP
  • EtherCAT
  • Profibus
  • RK512
  • OPC UA
  • serial fieldbus
