Abstract
A sensing system for an agricultural combine that measures crop material flow between the threshing system and the sieves. A number of sampling positions are provided along the longitudinal axis of the threshing system. A sensing member with a vibration sensor is provided at each sampling position to measure the volume of material flow between the threshing system and the sieves. In a rotary threshing system the sensing members are hollow tubes that are radially shaped to wrap around a portion of the outside of the concave or the grate.
