In cab Terminals offer a monitoring and application control system for self-propelled / trailed belt spreaders spreading lime / granular materials. Forward speed measurement enables full proportional control, to maintain (within limits) a set application irrespective of changes in forward speed. The four major components are the head unit, Spreader ECU, Load Cell ECU and Loadcells.
Machines without loadcells: The system relies on volumetric calculation from the known gate height and width, and a known product density (or selecting the product from a pre-defined list). It works best for relatively free-flowing material of consistent density.
Machines with loadcells: Loadcells enable fully-automatic, continuous calibration. There are advantages for controlling the rate of material with more variable density. By constantly measuring the weight of product in the spreader, the floor speed is continuously adjusted to achieve the correct target application rate. The system therefore quickly reacts to changes in product characteristics or spreading conditions without having to adjust or re-calibrate the machine.
