Ultraschallanemometer ohne bewegliche Teile
wetter wasser energie gas flux and turbulence bauwerke boden

Überblick

Das Windsonic4 ist ein zweidimensionales Ultraschall-Anemometer zur Messung von Windgeschwindigkeit und -richtung. Es bietet eine alternative zu traditionellen mechanischen Windsensoren und hat keine beweglichen Teile. Es gibt ein SDI12-Signal aus, das direkt mit einem CR200(X), CR800, CR850, CR1000 oder CR3000 und auch einigen älteren Datenloggern ausgelesen werden kann.

Für Gegenden mit viel Schnee oder Eisbildung ist der Windsonic nicht geeignet, da er keine Heizung hat. Auf Anfrage können wir Ihnen gern einen beheizten Windsensor empfehlen.

Bitte beachten: Die angebotenen Halterungen können sich je nach Campbell Vertretung unterscheiden.

Funktionen und Vorteile

  • Low maintenance—no moving parts significantly reduces maintenance cost and time
  • Provides a minimum detectable wind speed of 0.01 meters per second
  • Compatible with most Campbell Scientific data loggers

Technische Beschreibung

The WindSonic4 uses two pairs of orthogonally oriented transducers to sense the horizontal wind. The transducers bounce the ultrasonic signal from a hood, thus minimizing the effects of transducer shadowing and flow distortion.

Unlike mechanical anemometers, the WindSonic4 has no moving parts to be periodically replaced—minimizing routine maintenance costs.

Mounting

The WindSonic4 is shipped with the 17387 mounting kit. This mounting kit is used to attach the sensor to a CM202, CM204, or CM206 crossarm. The crossarm is then mounted to a tripod or tower.

Data Logger Considerations

The WindSonic4 is connected to one control port, +12 Vdc, and ground. Up to ten WindSonic4s (each with a unique address) can be connected to one data logger control port.

Programming

The SDI12 instruction is used to collect data from the WindSonic4.

  1. Is it possible for a WindSonic to operate in extreme conditions like snow, glacial temperatures, and freezing rain?

    Yes, as long as these two conditions are met:

    1. There are no obstructions in the measurement volume.
    2. The temperature is between -35 to +70 degrees Celsius.
  2. Can the WindSonic produce an output of 4 Hz or higher frequency?

    The fastest output frequency is 4 Hz for the WindSonic1 and 1 Hz for the WindSonic4. 

  3. Where is the interface cable for the WindSonic?

    All WindSonics (option 1 or option 4) are shipped from Campbell Scientific with an interface cable. If the cable has been lost, order a replacement. Order model WINDSONIC1CBL-Lxx for an option 1 or WINDSONIC4CBL-Lxx for an option 4, where xx is the cable length. The maximum cable length is 50 feet for option 1. The maximum cable on the SDI-1 bus is 200 feet.

  4. What is the optimum calibration frequency for a WindSonic?

    There are no user-serviceable parts on the WindSonic1 and WindSonic4. Should the WindSonic require service, it will start setting diagnostic flags. Campbell Scientific recommends that all datalogger programs record the total number of times the flags are set in an output period. For details, see the WindSonic Instruction Manual.

  5. Can vertical wind speed be measured by rotating the WindSonic 90 degrees?

    The WindSonic is not suitable for measuring the vertical wind component. The WindSonic measures the wind that passes through its measurement volume. It does not care what the orientation is. If the WindSonic is turned on its side, the reflecting top and body of the sensor will cause massive flow distortion of the wind vector, specifically for the horizontal component that is perpendicular to the reflective top. This flow distortion will most likely result in erroneous vertical wind measurements.

  6. The WindSonic has the average 1 Hz output of 40 Hz block measurements. What does the 40 Hz block measurement mean?

    The fundamental measurement frequency of the WindSonic is 40 Hz (40 measurements per second). These measurements are then averaged to give an output at some slower output frequency. For a WindSonic programmed to produce 1 Hz data, all 40 measurements are averaged. (This is called a block average.) For a WindSonic that is programmed to produce 4 Hz data, each output is the block average of 10 fundamental measurements.
