The instruments of the series HD51.3D… are 2-axis ultrasonic static anemometers. In addition to the measurements of wind speed and direction, they also provide the U-V Cartesian components of wind speed and the Wind Gust values. The average of wind speed and direction over a period configurable up to 10 minutes is calculated. Versions with housing in technopolymer or in anodized aluminium alloy with anti-corrosion coating which allows the instrument to be used even in a particularly aggressive atmosphere (e.g., marine environment) are available. The versions with housing in technopolymer can optionally be equipped with an integrated heater, in order to prevent the accumulation of snow and ice formation, allowing accurate measurements in all environmental conditions. The versions with housing in anodized aluminium alloy are always equipped with an enhanced heater, for rapid defrosting. The anemometers can optionally integrate the atmospheric pressure measurement. The versions with housing in technopolymer can optionally also integrate the temperature, relative humidity and global solar radiation measurements, making the instrument a compact and light meteorological station. 

Available outputs:

  • RS232, RS485 and RS422 isolated serial outputs with NMEA and MODBUS-RTU standard protocols and ASCII proprietary protocol.
  • Two analog outputs, for wind speed and direction or for velocity U-V cartesian components, which are factory-configurable within 4÷20 mA (standard), 0÷1 V, 0÷5 V or 0÷10 V (to be specified when ordering).
Mounting on ∅ 40 mm mast. The optional function of detecting the orientation (compass) and tilt angles allows the spatial orientation of the instrument to be determined at any time, allowing installation on mobile vehicles (for example boats) or, in the case of fixed installations, the automatic correction of both a possible misalignment with respect to the vertical axis and an imperfect orientation of the instrument towards the North. The high immunity to electromagnetic disturbances makes the anemometer suitable for measurements in electrically noisy environments (e.g., industrial environments, wind farms, etc.). All instrument sensors are factory-calibrated and do not require additional interventions of the user (field calibration is not required). The absence of moving parts minimizes the instrument maintenance.The anemometers satisfy the requirements of the following standards:

  • MIL-STD-810G Method 509.6 and EN ISO 9227:2017 (salt fog anti-corrosion test)
  • MIL-STD-810F Method 521.2 (anti-icing/freezing rain test) – Only versions with housing in anodized aluminium alloy
  • EN 60945:2002 Sect. 8.7 / IEC 60068-2-6 (vibration resistance test) – Only versions with housing in anodized aluminium alloy 

HD51.3D4R e HD51.3D4R-AL are 2 axes ultrasonic static anemometers with integrated heater. The heater prevents the accumulation of snow and ice formation, allowing accurate measurements in all environmental conditions.

HD51.3D4R-AL is equipped with an enhanced heater, for rapid defrosting, and an anodized aluminum alloy housing with anti-corrosion coating that makes it possible to use the instrument even in a particularly aggressive atmosphere (e.g., marine environment). The anemometer satisfies the requirements of the MIL-STD-810G Method 509.6 standard (salt fog anti-corrosion test). The high immunity to electromagnetic disturbances makes the anemometer suitable for measurements in electrically noisy environments (e.g., industrial environments, wind farms, etc.).

PC application software.
The PC software HD52.3D-S allows configuring the instrument, viewing the real time meas-urements both graphically and numerically, managing graphical presentation, printing and export in Excel®  format of the data acquired with the Monitor function.
