HD51.3D… is a series of high performance two-axis static ultrasonic anemometers for accurate measurements in all environmental conditions.

Available in different combinations for the measurement of: Wind speed (up to 85 m/s), Wind direction, Cartesian U-V components of wind speed, Wind Gust, relative humidity and temperature (optional), global solar radiation (optional), atmospheric pressure (optional).

This model is equipped with an upgraded heater, for quick defrosting, and an anodised aluminium alloy case with anti-corrosion coating that makes it possible to use the instrument even in particularly aggressive environments. The anemometer meets the requirements of MIL-STD-810G Method 509.6 (salt spray corrosion test). High immunity to electromagnetic interference makes it suitable for measurements in electrically noisy environments.

All models have RS232, RS485 and RS422 serial outputs. NMEA, MODBUS-RTU and proprietary ASCII communication protocols. Two analogue outputs for wind speed and wind direction, factory configurable as 4÷20 mA (standard), 0…1 V, 0…5 V or 0…10 V.

Operating temperature -40…+70 °C. Instrument power supply 12…30 Vdc. Heater power supply 24 Vdc. Software HD52.3D-S, for instrument configuration and monitor, downloadable here.

Applications:

  • Wind farms monitoring
  • Remote weather stations
  • Buildings, constructions and bridges control
  • Ports, airports and heliports
  • Road and railway tunnels
