Description

  • Large liquid crystal display which is easy to read under almost any conditions.
  • Three operating modes: wind speed, average wind speed, and maximum wind speed.
  • The display units can be changed at any time, with choices to suit a wide variety of applications (knots, meters per second, kilometers per hour, miles per hour, or feet per minute).
  • A precision ultra-light impeller mounted in jewel bearings measures wind speed.
  • This impeller yields high accuracy (± 3%) and a low startup speed (0.3 M/S).
  • Shock-mounted in a glass reinforced plastic housing which can simply be popped out and replaced with a new assembly in the event that the impeller mechanism becomes worn or damaged.
  • The Kestrel is waterproof and floats.
  • The hard case slips on and off easily, protecting the display and all moving parts from damage.
  • Performance is guaranteed for one full year.
  • US Patent No. 5,783,753.
Performance Specifications
  • On-axis Accuracy: +/-3% of reading or +/-least significant digit, whichever is greater.
  • Off-axis Response: -1% @ 5 °, -2% @ 10 °, -3% @ 15 °.
  • Calibration Drift: <2% after 100 hours operation at 7 M/S.
  • Minimum Speed: 0.3 M/S (~0.6 KT, 1KM/H, 0.7 MPH, 60 FPM).
  • Maximum Speed: 40 M/S (~78 KT, 144 KM/H, 89 MPH, 7830 FPM). Some loss of accuracy from bearing wear may occur with sustained operation over 25 M/S.
