Description
The WINDCRANE V20 wind vane is a high-accuracy wind direction sensor for use with the WINDCRANE wind monitoring system and use with boom wind.
How does a wind vane work? It measures wind direction by aligning itself with the wind, using its tail and potentiometer to provide precise directional readings.
Includes
- V20 Wind direction vane with a 1m cable and M12 connector and Z mast
- 10m extension cable with M12 connectors
- U-bolt clamp
