  • Page 7: Specification Summary

    2.0 INTRODUCTION MODEL 81000 The Young Model 81000 measures three dimensional wind velocity ULTRASONIC ANEMOMETER and speed of sound based on the transit time of ultrasonic acoustic signals. Sonic temperature is derived from speed of sound which is corrected for crosswind effects.

  • Page 8: Command Menu

    SETUP allows editing operating parameters to suit the needs of a connections. If the problem cannot be corrected, contact your particular application. The SETUP menu and detailed explanation YOUNG representative. of each menu item follows: 4. Verify sensor response by gently blowing through the measuring SET PARAMETERS section.
  • Page 9 7) 3D SPEED Normally, this value should not be changed since each instrument 8) AZIMUTH 9) ELEVATION is calibrated in the YOUNG factory wind tunnel. Users who wish A) SOS to alter the scaling based on independent calibration assessment B) Ts may use this parameter to do so.
  • Page 10 RA! cmds (ms) NMEA sends wind speed and direction in NMEA marine format to Young Model 06206 Marine Wind Tracker display or other NMEA device. The sentence is $WIMWV,aaa,R,ss.s,N,A where aaa = wind direction angle in degrees and ss.s = wind speed in knots.

  • Page 11: Application Notes

    81000 is individu- ally calibrated in the YOUNG factory wind tunnel (NIST traceable) VOLTAGE OUTPUT FULL SCALE = 5 to generate a unique correction table which is stored in the unit.
