Abstract:

The patent relates to a device whereby a wind vane rotates the arm of a potentiometer having a three-terminal voltage divider. The filtered out-put voltage of the potentiometer is an indication of wind direction. Avoidance of any discontinuities in the output voltage due to the potentiometer gap is accomplished by a logic device and a relay which switches the voltage range of the potentiometer whenever the arm crosses the gap. Therefore, the filtered output of the potentiometer will be a continuously varying voltage extending over three full revolutions of the wind vane.
