Description

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

Heated components:
• base plate
• cover plate
• sensor receiving sockets
• ultrasonic transducers

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
