Aperçu

The 03301, manufacted by R. M. Young, is the wind vane included with our Wind Sentry Sets (03002, 03001). Although some customers have valid applications that require monitoring wind speed only (without direction), monitoring wind direction only (without wind speed) 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

Data Logger Considerations

The wind vane is measured by the BrHalf Instruction in CRBasic, and by Instruction 4 (Excite-Delay-SE) in Edlog.

Développer toutRéduire tout

  1. Is anything needed to attach the 03301-L to a section of pipe for connection with a Nu-Rail® fitting?

    No.

  2. Can replacement bearings for the 03301-L be ordered? If so, are they replaceable by the user?

    The wind vane does not use bearings, so replacement is not necessary. Typically, the part that needs replacing is the potentiometer. Campbell Scientific recommends factory replacement.

  3. En utilisant Short Cut, comment puis-je calculer la moyenne de la direction du vent ?
    1. En utilisant Short Cut, cliquez sur une des girouettes proposées dans la liste Selected Sensors de l'écran Outputs.
    2. Deux options de sortie sont disponibles : Sample (échantillon) et WindVector (Vecteur vent). Selectionnez WindVector.
    3. L'instruction du vecteur vent  WindVector a diverses options de sortie. Selectionnez une des options avec la direction moyenne du vent.
