Previous studies have shown that capacitance throughput units can be used as a source of output voltage signal for satisfactory hop-picking machine throughput control. This study investigated the possibility of capacitance throughput sensor integration into some appropriate location of a PT-30 stationary hop-picking machine, the possibility of its calibration, the possibility of control procedure development, and its performance verification under operational conditions. A capacitance throughput sensor was integrated into the pocket belt conveyor that transports freshly picked hop material to the separation part of the machine. Control of the frequency converter, which powers the electric motor of the pocket belt conveyor, was realized by a simple controller application, with a graphic touch panel serving as an interface with the machine operator. The mathematical model of capacitance sensor sensitivity distribution helped us to better understand its function in its practical application on a pocket belt conveyor with metal pockets. A linear dependence of sensor output voltage on wet hop material throughput was determined for a throughput range from 0.38 to 0.66 kg s(-1) with a suitable coefficient of determination (R-2 = 0.98). Based on calibration results and harvesting losses measurement, a simple mode of automatic control algorithm was developed. The functioning of the control system was observed for 2 h (picking of hop plants from one trailer) during an ordinary harvesting day with the aim to verify its performance. In the case of throughput automatic control usage, the periods with high material throughput rates (higher than 0.5 kg s(-1)), which are the cause of losses, occurred six times less in comparison with the situation without control. The peaks of harvesting losses dropped from 8% to 4%. The machine operator quickly evaluated this situation and spontaneously started to use the automatic control mode after the control system was installed to the machine.
