Measurement of hop material throughput by capacitive sensor

Popis výsledku v původním jazyce

The information about instantaneous hop material throughput could be used for stationary hop picking machine control which should bring higher harvesting efficiency with better quality of harvested product. In this research, a capacitive throughput sensor as a source of electronic control signal has been tested. Linear dependence of capacitive sensor output voltage on wet hop material throughput was found. Coefficients of determination R2 ranged from 0.92 to 0.97. Nevertheless, the behaviour of capacitive sensor was necessary to explain by a mathematical model of the electric field intensity. This model was created by using of finite elements method. Based on the experiments carried out it can be concluded that the output voltage signal from capacitivesensor can be used for the aim of stationary hop picking machine throughput control with adequate precision under real harvesting conditions.
