_______________

The Research range of 3-axis ultrasonic wind sensors are all-round wind and turbulence sensors providing accurate measurements of horizontal and vertical wind speed and direction. They offer a higher sampling rate than the Professional range.

The entry level USA-1 Research 100 model has a sampling rate of up to 50 Hz and has an internal memory for data storage (around 12000 standard data sets) and a battery buffered clock. It has no moving parts, is maintenance free and comes with a field calibration kit for user confidence checks.

What it does

The USA-1 Research 100 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 0-540ºo 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 synchronized 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 ie:

SNC 940815090015 UTC

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

_____________________________________________________________________

where

x	mean x wind component in the sensor related orthogonal coordinate system (parallel to the black arrow on the electronic box); unit m/s
y	mean y wind component in the sensor related orthogonal coordinate system (horizontally perpendicular to x); unit m/s
z	mean z wind component in the sensor related orthogonal coordinate system (vertical); unit m/s
T	mean temperature; unit ºC
