However, the wind direction sensor is installed at the top of the wind tower, the wind tower is as high as more than 10 meters, the service stipulates that the wind tower height is 10.5 meters, and the verification difficulty during installation is very high. When the operator carries the compass to carry out the orientation contrast, because the compass is far away with the north arrow on the shell of wind direction sensor, can only observe the sighting by the people's eye and realize the contrast, there is great error, in addition, the pointing of compass receives the influence of levelness great, is difficult to guarantee the compass level when the operation in high altitude. Therefore, it is difficult to ensure the accuracy of north pointing when the wind direction sensor is installed.
