Grain Yield Monitor

 As the clean grain elevator paddles rotate around the top of the clean grain elevator, the grain is expelled from the elevator by centrifugal force Grain mass flow is most commonly measured using a load cell with an impact plate attached to the load cell located at the top of the clean grain elevator. and makes contact with the impact plate attached to the load cell. The force applied by the grain is converted to an electrical signal by the load cell that is used to estimate the mass flow of the grain. A calibration of the sensor to develop a relationship of the amplitude of the electrical signal to grain mass flow and is calibrated on a harvester specific basis with the grain mass reported on a wet basis. This technology was developed and first commercialized by Ag Leader Technology.
