____________________

 The Wind Research 200 is a very fast response 3-axis ultrasonic anemometer for highly accurate measurements of horizontal and vertical wind speed and direction in extreme icing conditions and freezing precipitation.

The Wind Research 200 has a brass measuring head to optimise the powerful heating which keeps the measuring head ice free.

This makes the Wind Research 200 sensor ideal for use where extremes of weather or heavy icing conditions are experienced and comes with a field calibration kit for user confidence checks and a robust transport case.

What it does

The Wind Research 200 provides the following information in various data outputs which can be polled or output automatically:

  • instantaneous and averaged data for the three component wind vectors
  • virtual temperature
  • horizontal wind speed and direction plus vertical wind component
  • chart mode (provides 0-540o wind direction and speed values)
  • NMEA value outputs
  • raw data mode (uncorrected) or 2D / 3D head corrected data

Data can be averaged by several methods:

  • scalar or vectoral
  • clock synchronised or running average
  • separate output rates and sampling times

Some other important features:

  • user definable north orientation (range 0-359o alignment off axis)
  • data quality control to perform confidence checks on raw data
  • date / time stamps with several options
  • check sum information
  • calibration validity output monitoring

Examples of data output

Normal data example (instantaneous). Every data string starts with a header line that consists of the string SNC followed by a space and 12 characters for the date/time stamp, another space and finally the UTC string i.e.:

SNC 940815090015 UTC      HTR

x = 1.83     y = -0.79    z = 0.20       T = 20.17     

_____________________________________________________________________

where

HTR informs the user that the sensor head heating is turned on
x mean x wind component in the sensor related orthogonal co-ordinate system (parallel to the black arrow on the electronic box); unit m/s
y mean y wind component in the sensor related orthogonal co-ordinate system (horizontally perpendicular to x); unit m/s
z mean z wind component in the sensor related orthogonal co-ordinate system (vertical); unit m/s
T mean temperature; unit ºC
