ABSTRACT:
An improved flow sensor is disclosed for use with a crop harvesting device to determine flow volume of a crop yield product. The improved flow sensor is of the type which uses a strain gauge and includes an improved probe coupled to the strain gauge and adapted to cooperate with the strain gauge to produce a signal indicative of pressure being applied to the probe by the crop yield product. The improved probe includes first and second connection members adapted to couple the probe to the strain gauge. A probe middle portion is coupled to each of the first and second connection members and extends from a location between the first and second connection members into a middle portion of the flow path of the crop yield product. First and second probe legs are coupled to and extend from first and second sides of the probe middle portion into first and second sides of the flow of crop yield product.
