ABSTRACT:
Sensing structure including a microwave sensor monitors the velocity, mass flow and moisture of cotton in a harvester air duct. As the flow of cotton in the air duct nears maximum capacity, the cotton velocity will decrease and the sensor provides a signal to the controller so that harvester speed will be reduced. Cotton mass and moisture level signals are used to determine the percentage capacity and anticipate loading of the cotton cleaner or other crop processor. The signals can also be used to control cross auger and impeller speed to even out the flow of cotton within the air duct system in highly variable yield conditions in the field.
