HD51.3D Two-Axis Static Ultrasonic Anemometer

HD51.3D Two-Axis Static Ultrasonic Anemometer

Deltaohm HD51.3D is a series of high-quality two-axis static ultrasonic anemometers by which you can carry out accurate measurements in all environmental conditions. Deltaohm HD51.3D Two-Axis Static Ultrasonic Anemometer is available in different combinations for the measurement of:

(All combination options are available with heating)

  • Wind direction
  • Wind speed (up to 85 m/s)
  • Wind Gust
  • Cartesian U-V components of wind speed
  • atmospheric pressure (optional)
  • global solar radiation (optional)
  • relative humidity and temperature (optional)

Regarding harsh environments, the HD51.3DR-AL two-axis static ultrasonic anemometer is also available for measurement of wind direction, Cartesian U-V components, wind speed (up to 80 m/s), wind Gust and atmospheric pressure (optional for HD51.3D4R-AL).

This model is provided with an anodized aluminum alloy case with anti-corrosion coating which enables it to be used in aggressive environments. Also, for or quick defrosting HD51.3D Two-Axis Static Ultrasonic Anemometer is equipped with an upgraded heater.

Moreover, Deltaohm Two-Axis Ultrasonic Anemometer meets the requirements of MIL-STD-810G Method 509.6 (salt spray corrosion test). Also, high immunity to electromagnetic interference makes it possible to be used in measurements in electrically noisy environments.

Available outputs of HD51.3D Two-Axis Static Ultrasonic Anemometers

  • RS485, RS232 and RS422 serial outputs with MODBUS-RTU and NMEA standard protocols and ASCII proprietary protocol.
  • Two analog outputs for wind direction and wind speed, or for velocity U-V cartesian components, which are factory-configurable within 4÷20 mA (standard), 0÷10 V, 0÷5 V or 0÷1 V (to be customized when ordering).
