ABSTRACT:
The grain moisture sensor of the present invention includes a plurality of conductors for communicating a variable voltage between two points. The conductors are mounted on the continuous flow dryer wall between the exterior and interior walls, in the heat plenum and oriented such that the grain flows between the conductors in response to the action of the variable discharge means. The sensor further includes electrical circuitry for measuring the capacitance of the conductor, calculating the percent moisture content of the grain and controlling the speed of a discharge means so as to control the discharge of grain from the dryer in response to the moisture content of the grain being lowered to a predetermined level.
