Wind Sentry Vane

Campbell Scientific

The 03301 Vane is a component of the Wind Sentry Sets. Although wind vanes have valid applications that require monitoring wind speed only (without direction), monitoring wind direction only provides little useful information. For this reason, the 03301 is available for two purposes:

  1. As a replacement vane for a Wind Sentry Set that requires replacement of the vane only

  2. As an "upgrade" for a customer that originally purchased only the anemometer and now wants to add the vane to make a complete Wind Sentry Set
