HD 2003.1 : 3-AXIS  ULTRASONIC  ANEMOMETER

HD2003.1 Three Axis Ultrasonic Anemometer measure the speed and direction of wind, the U-V-W Cartesian components of speed, sound speed and sonic temperature.

The HD2003.1 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.

• 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 demo software, configurable 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.

 

Typical applications:-

• Meteorology
• Aviation and Navigation
• Tunnels, Highways
• Climatology
• Sport and winter stations
