Profis weighing technology – Who weighs wins!

No calibration. Top up the spreader hopper up and off we go! There is nothing simpler.

The weighing system offers controlled convenience and more reliability. It enables on-line determination of the different spreading material properties with two 200 Hz load cells – providing a high level of measuring accuracy. It automatically compares the

actually applied rate with the pre-determined rate. Deviations in the flow characteristics, for example when spreading blended mineral fertilisers, are detected and the spreader is re-adjusted automatically via the electric metering shutter slides. In addition, for field-related nutrient application, for example, the applied rate is precisely documented. In addition, the applied rate is accurately documented for field-related

nutrient application. In addition, the application rate can be altered at any time by pressing a button on the ISOBUS terminal.

The advantages
Regulating/calibrating under all operating conditions:

  • Side, border and water course spreading 
  • Part-width section control 
  • Using application maps/N-sensors 
  • Spreading of mixed fertilisers

Accurate weight measurement:

  • display of residual volume 
  • Residual area and residual hopper level display 
  • Documentation of the total volume spread

Flashing followed by the constant lighting up of the work lights signals that the fill level has been reached.

Tilt sensor for steeper sloping terrain

On the Profis system, any possible effects of gravity on the measuring of the hopper contents are taken into account during work with the help of a tilt sensor: A twin-axis tilt sensor that assesses the front and back tilt as well as to the left and right, corrects measurement errors that may arise when going up and down hills or when driving across a hillside.

For simplifying the mounting of the ZA-TS onto the tractor in the horizontal position, the angle of the ZA-TS Profis is comfortably displayed in the ISOBUS terminal.

The spread rate regulation between the Profis weighing system and the FlowControl sensors is a unique selling feature for AMAZONE.

ProfisPro for Tronic and Hydro 
The intelligent ProfisPro weighing system is available for both the Tronic version with mechanical drive, and the Hydro version with hydraulic drive.

Rate calibration completely thought through: ProfisPro

The correlation between application rates and the torque generated at the spreading disc at different working widths has been determined for all types of fertiliser on the basis of numerous spreading tests. Put simply: low application rates generate less torque on the disc than higher rates.

FlowControl reliably monitors the torque on each spreading disc drive independently and can immediately adjust the position of the application rate shutters in the event of a deviation from the target rate.

In addition, the driver has an overview of the actual quantity remaining in the hopper at all times as well as the possibility to display the remaining travelling distance until empty.

Optimised spread rate from the very first second

This combination of weighing system and FlowControl enables the fertiliser spreader to use torque in order to regulate its theoretical application rate over the complete spreading process. The Profis weighing system monitors the actual spread rate every 25 kg. This allows FlowControl to recalibrate itself at regular intervals. This takes place without any need to stop. The ProfisPro intelligent weighing system means that the spread rate is optimised from the very first second of the spreading process.

The benefits

Absolute precision from the very first second 

  • Simultaneous regulation via the weighing system and torque measurement 
  • Calibration and regulation of application rate in all field situations (border spreading/SectionControl)

Exact application rate in any field situation 

  • Regulation of the shutter slides, even when using application maps, independent of which side 

Reliable application down to the last kilogram 

  • Detection of empty runs and blockages 
  • Absolute weight recognition using the weighing system
