Ultrasonic Anemometer compact

The Ultrasonic Anemometer compact serves for the 2-dimensional acquisition of the horizontal components of the wind velocity, the wind direction and of the acoustic-virtual temperature.

The instrument is particularly suited for the use in the fields of

•

Industry automation
• Traffic engineering, aviation and navigation
• Regenerative energy production, wind energy plant
• Meteorology
• Climatology
• Wind warning devices, building construction and building security

The following measuring values are available

• Orthogonal wind velocity vectors (X- and Y-distance)
• Scalar/vectorial wind velocity, wind direction
• Acoustic-virtual temperature
• NMEA data protocol
• ASCII THIES FORMAT
• Analogue data output

The measurement principle allows, compared to the classic anemometers, an inertia-free measurement of running variable dimensions with highest precision and accuracy.
The measuring values can be output digitally and/or in analogue form.
The serial or analogue output of the data is carried out alternatively as instantaneous value or as gliding mean value with selectable time frame.
If necessary, the instrument is automatically heated in case of critical ambient temperatures.
The possibility of malfunction, caused by icing, is minimized. The sensor arms and the ultrasonic sensors are heated
