Ultraschall Anemometer 2D Compact

Part number: 4.3875.6x.xxx

  • Description

    4.3875.xx.xxx
    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.

    • Heater with 48V DC supply for increased icing resistance

    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. 4.3876.2x xxx is equipped with an additional baro transmitter.

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