<p>A wind vane drives a movable contact of a voltage divider comprised of a 360 DEG potentiometer. The movable contact is connected into an electrical summing point in an electrical circuit which responds to a discontinuity in the potentiometer output to add or subtract a sufficient electrical quantity at the summing point to compensate for the discontinuity. In addition, at the end of the electrical range of the circuit an electrical quantity equivalent to a predetermined amount of vane rotation is added or subtracted from the summing point as required to reposition the electrical sum to a valve intermediate of its range.</p> |
