HD2003 and HD2003.1 are three axis ultrasonic anemometers, they measure
the speed and direction of wind, the U-V-W Cartesian components of speed, sound speed and sonic temperature.
The HD2003 allows also to detect temperature and relative humidity of the air and barometric pressure.
The HD2003 main features are:
� Determination of the anemometric quantities represented in diverse measurement
units: wind speed and direction, U-V-W Cartesian components of speed, sound speed, sonic temperature.
� ( HD2003 Model) additional output quantities: Temperature, Relative Humidity
and Pressure.
� 5 analogue voltage or current outputs, with different measuring ranges.
� RS232 and Multidrop RS485 Serial Communication interfaces.
� Configurable output rate of digital output data string.
� Configurable average periods 1÷ 60sec and 1÷ 60min. for all output quantities.
� Algorithmic raw date processing and validation, assuring ± 1% precision to
anemometric quantities.
� Digital high frequency data acquisition mode with 50Hz data output.
� Self-diagnosis with error checking and report.
� Reliability and precision on whole measuring range, no additional calibration required.
� Flexible, easy-to use operating software, confi gurable according to the user� s
needs through Computer interface.
� User interface for � Setup� management and software upgrade through RS232 or
RS485.
� Automatic alignment to the magnetic North through built in compass.
� No moving part, with reduced maintenance and service costs.
� Rugged and reliable structure, suitable for continuous operation even in severe environmental conditions.
� Low power consumption.
� ( On request) Heaters Option: built-in heating device of sonic transducers, to prevent ice and snow formation. Assures correct measurements even in presence of sleet or snow.
Typical applications:
- Meteorology
- Aviation and Navigation
- Tunnels, Highways
- Climatology
- Sport and winter stations
- Safety in yards
- Industrial buildings
