Ultrasonic Anemometer 1D

Part number: 4.3866.0x.xxx

  • Description

    4.3865.0x.xxx
    The Ultrasonic Anemometer 1D serves for the measurement of the horizontal air flow
    of a fixed flow direction and the acoustic-virtual temperature.

    The device has a 8-pol. plug connector

    Heated components:
    • sensor arms
    Different measuring values are
    available, among others:
    • Flow vector
    • Scalar flow velocity
    • Acoustic-virtual temperature
    • Standard deviation of the wind velocity
    • Standard deviation of the scalar air flow
    • Standard deviation of the acoustic-virtual temperature
    • Flow velocity of the gust

    The instrument is especially suited for the use
    • In the traffic engineering
    • Indoor flow measurement
    • In tunnels
    • In tubes

    The measurement principle allows, compared to the classic anemometers, an inertia-free measurement of running variable dimensions with highest precision and accuracy. It is especially suited for the measurement of gust- and peak values. 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 sensor arms are automatically heated with critical ambient temperatures.
