Sensor for only measuring wind direction
气象 应用支持 水资源 应用支持 能源 应用支持 湍流通量 应用支持 基础结构/工业设施 应用支持 土壤 应用支持

概览

03301 叶片，包括在我们的03002和03001中。一些我们的用户可能只需要测量风速（不包括风向），或只测量风向（不包括风速）。而03301有两种用途：
  1. 只作为风速计的备用叶片使用或
  2. 作为用户的升级版的装备，最初只购买风速计而现在想添加叶片做出一套完整的风力风速风向系统。

Data Logger Considerations

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

  1. 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.

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

    No.

  3. Using Short Cut, how can the average wind direction be calculated?
    1. Using Short Cut, click the applicable wind direction sensor in the Selected Sensors list of the Outputs screen.
    2. The two output options enabled are Sample and WindVector. Select WindVector.
    3. The WindVector instruction has output options. Select an option with mean wind direction in it.
