Thies Clima - Model 4.3875.xx.xxx -2D Compact Ultraschall Anemometer

The following measurement data are available:

• Orthogonal wind velocity vectors (X- and Y-distance)
• Scalar /­ vectorial wind velocity wind direction
• Acoustic-virtual temperature

The instrument is especially suitable for the use in the fields of:

• Regenerative power generation, wind power plants
• Industry automation
• Wind warning devices, building construction and building security
• Traffic engineering, aviation and navigation
• Meteorology
• Climatology

The measurement principle allows, compared to the classic anemometers, an inertia-free measurement of running variable dimensions with highest precision and accuracy.

• The data can be served
• analogically*, as standard signal or /­ and digitally in
• ASCII THIES- Format or
• binary as MODBUS RTU protocol

If necessary, the instrument is automatically heated at critical ambient temperatures. Thus, the risk of malfunction caused by icing is minimized.

The model no. 4 3875 2x xxx is equipped with an additional baro transmitter.

* only in HD (half duplex) operation no output of virtual temperature
