外文摘要：A material flow sensor for a harvesting machine comprising an acoustic chamber comprising an impact plate and a housing, microphone, a pneumatic impulse line connecting the housing and the microphone, and an electronics module, wherein the housing is shaped so as to direct sound waves created by crop matter striking the impact plate into the pneumatic impulse line, wherein the sound waves move through the pneumatic impulse line into the microphone, which detects the sound waves and converts them into an electrical signal that is a representation of the sound power derived from the sound waves, which in turn is a representation of the mass of the crop matter striking the material flow sensor.
