Air Speed
2 Axis Ultrasonic Anemometer
The HD52.3D… are 2 axes ultrasonic static anemometers for measuring:
- Wind speed and direction, U-V Cartesian components of wind speed
- Wind Gust – Measurement available only with MODBUS-RTU and SDI-12 protocols
- Relative Humidity and Temperature (optional),
- Global Solar Radiation (optional)
- Barometric pressure (optional)
- Rainfall (optional)
All models are equipped with a magnetic compass.
Advantages:
- No moving parts = less maintenance.
- High sensitivity for detecting very low speeds, which are not detectable by traditional methods.
- The low power consumption allows installation at remote sites using a small solar panel and battery.
- The heating option ‘R’ prevents the accumulation of snow and ice, allowing accurate measurements in all environmental conditions.
- Fast and easy installation, and alignment facilitated by the built-in compass.
- MODBUS-RTU output allows instrument networking.
- Accurate and reliable. Factory calibrated in an ISO/IEC 17025 accredited göttinger-type wind tunnel equipped with laser doppler anemometry.
