Abstract
A grain mass flow sensor assembly of an agricultural harvester has a continuously curved sensor plate positioned to receive a grain flow from an exit of the grain elevator. The continuously curved sensor plate is configured to change the direction of the grain flow in order to generate a reaction force for measuring the grain mass flow rate of the grain flow. The continuously curved sensor plate is attached to a sensor plate to load cell mounting bracket. The sensor plate to load cell mounting bracket is attached to a single point load cell torque or moment compensated force transducer at a single mounting point. The single point load cell torque or moment compensated force transducer produces a mass flow sensor signal that is proportionate to the grain mass flow rate.
