- Page 2 I. General Model W639-ED1 is an Aero plane type Wind speed & direction sensor. Wind speed is output with pulse voltage that is converted by propeller rotation. As for wind direction, the rotation angle of the counterbalanced tail is detected with a brushless potentiometer and voltage of 0 to 1V is output at 0 to 360 °...
- Page 3 Ⅲ. Handling 1. Installing the propeller of the sensor (refer to the attached sheet No. 1) Be sure to fully tighten the screw. If the propeller is improperly installed, it may drop, resulting in danger.
