International Classification:

G01F 130

US Classification:

7386173

Abstract:

A mass flow sensor for a combine is positioned in the transition housing between the paddle elevator of the clean grain elevator and the loading auger of the clean grain tank. The mass flow sensor comprises an impact plate having an arm which is axially aligned with the predominant grain flow from the paddle elevator. The arm is coupled to a force measuring assembly having a potentiometer for generating an electric signal that is proportional to impact force.

Abstract:

A moisture sensor for an agricultural combine comprises a chamber having an inlet and an outlet and a paddle wheel flow controller located adjacent to the outlet. The paddle wheel flow controller is rotated by an electric motor which is controlled by an electronic controller. Grain from the clean grain elevator is directed through the inlet of the chamber past a capacitance sensor comprising a first, second and third plates. By measuring the capacitance of the grain, the moisture in the grain can be determined.
