general information:
HD51.3D4R and 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.).
The anemometers measure:
- wind speed up to 80 m/s (HD51.3D4R-AL) or 85 m/s (HD51.3D4R)
- wind direction
- wind gust
- atmospheric pressure (with internal sensor)
The average of wind speed and direction over a period that is configurable up to 10 minutes is calculated.
specifications:
| wind speed: | sensor: ultrasound measuring range: 0 to 85 m/s (HD51.3D4R) 0 to 80 m/s (HD51.3D4R-AL) resolution: 0.01 m/s accuracy: ±0.2 m/s or ±2 %, the higher value applies (0 to 60 m/s), ±3 % (> 60 m/s) |
| wind direction: | sensor: ultrasound measuring range: 0 to 359.9°. In order to avoid oscillations of the analog output around 0°, the extended range 0 to 539.9° can be set resolution: 0.1° accuracy: ±2° RMSE (wind speed >2 m/s) |
