Weighing system | Automatic rate control

Profis weighing technology – Who weighs wins!

No calibration. Just enter the spread rate and drive off! There is nothing simpler.

The weighing system offers controlled comfort as well as peace of mind. It works on-line to determine the different characteristics of the material to be spread via two 200 Hz weigh cells with the highest degree of measuring accuracy. It automatically compares the actual applied rate with the pre-determined rate. Deviations in flow behaviour, such as, for example with blended mineral fertilisers, are detected and the spreader automatically re-adjusts via the electric metering slides. The quantity applied is also precisely documented for the purpose of site-specific nutritional application. The application rate can be changed at the touch of a button via the ISOBUS terminal to provide a balanced nutrient supply.

Tilt sensor for steeper sloping terrain

Any possible influences due to a change in the centre of gravity are taken into account on the Profis by the on-the-move signal from the tilt sensor. The two-dimensional tilt sensor, which detects angles to the front and back or side to side, corrects any errors in the measuring procedure which might occur when driving up and down hills or when driving across a slope.

Low level sensors

When spreading on slopes or when border spreading it can happen that one hopper tip is emptied quicker than the other. In order to check each outlet apertures individually, AMAZONE therefore additionally offers low level hopper sensors. With a premature emptying of one side, the relevant hopper tip is indicated in red in the operator terminal so that the driver is warned in good time.
