HD 2003. HD 2003.1
THREE AXIS ULTRASONIC ANEMOMETER




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.
• Processing algorithms and validation of the raw measurement signals to provide a measure of greatness anemometer with ± 1%.
• Digital high frequency data acquisition mode with 50Hz data output.
• Self diagnostics with error checking and report.
• Reliability and accuracy throughout the measuring range without further calibration.
• Flexible. easy-to use demo software. configurable according to the user’s needs through Computer interface.
• User interface for managing the setup and software upgrade via RS232 or RS485.
• Compass magneto sensor for automatic alignment to magnetic north.
• No moving parts. maintenance costs and reduced service.
• Robust construction. suitable to operate continuously in harsh conditions.
• Low power consumption.
• (On request) Heating 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
