HD51.3D… – Ultrasonic Anemometer (Aluminium Alloy):
HD51.3D… is a series of high-performance dual-axis static ultrasonic anemometers for precise measurements in all environmental conditions.
All combos are available with heating. For particularly harsh environments, the HD51.3DR-AL model is available for the measurement of wind speed (up to 80 m/s) and wind direction, Cartesian U-V components, Wind Gust, and atmospheric pressure (optional – model HD51.3D4R-AL).
This model is equipped with an upgraded heater for quick defrosting and an anodized aluminum alloy case with an 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 RS-232, RS-485, and RS-422 serial outputs. NMEA, MODBUS-RTU, and proprietary ASCII communication protocols Two analog outputs for wind speed and wind direction, factory set to 420 mA (standard), 0….1 V, 0….5 V, or 0….10 V.
Operating temperature: -40…+70 °C Instrument power supply: 12–30 Vdc. the heater power supply is 24 volts. Software HD52.3D-S, for instrument configuration and monitoring, is downloadable here.
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.
