Ideal for wind-energy applications
Resumen
El A100LK es un anemómetro para uso en meteorología y para evaluación del recurso eólico. Su bajo consumo y amplio rango de voltaje de alimentación lo han hecho ser popular en instalaciones remotas donde no hay disponible 220Vac. Su señal de salida tipo pulsos/frecuencia es ideal para usarlo en nuestros dataloggers Campbell Scientific. El sensor está construido en una aleación de aluminio anodizado, acero inoxidable, y plásticos resistentes a la intemperie que le proporcionan una larga vida útil. Leer másVentajas y características
- IEC Class 1 performance
- Low power consumption
- High rate of pulses per revolution produced makes it suitable for wind-surveying applications where turbulence is estimated
- Bearings protected from the entry of moisture droplets and dust, resulting in an instrument suitable for permanent exposure to the weather

Descripción detallada
Rotation of the A100LK’s three-cup rotor is electronically converted to pulse output signals proportional to wind speed. The A100LK produces a higher rate of pulses per revolution (up to 13) compared to relay-based sensors, making it suitable for wind surveying where turbulence needs to be estimated.

Ultrasonic anemometers are unable to make measurements if the sonic path is blocked. The path may become blocked by water that puddles on the lower transducer face or droplets that hang from the upper transducers. Sonic wicks, which come with all sonics, can be placed on the transducers to wick away moisture from the faces of the transducers. Ensure that these wicks are removed during cold conditions to prevent ice from building up around them.
-
No. The offset is a function of temperature and time. Once a year, spot-check the sonic anemometer wind offset using the procedure outlined in the CSAT3B instruction manual. If the measured offset is outside the specification, return the sensor to the factory for calibration. To request a return material authorization (RMA) number, follow the steps listed on our Repair and Calibration page.
-
The CSAT3A or CSAT3B is calibrated over the temperature range of -30° to +50°C. The sonic anemometer operating temperature range can be shifted by 10 degrees to cover the range of -40° to +40°C. For low-temperature applications, it may be more appropriate to consider a heated version of our sonic anemometers.
The instrument will continue to operate outside the calibrated temperature range until the signal becomes too weak; however, the proper calibration will not be applied to the measurements because the calibration file only spans the specified temperature range.
-
Yes. The CSAT3B and CSAT3BH measurement frequency can be changed by the user. The user can either choose a prompted or unprompted output rate. The prompted output rate is based on the scan interval of the data logger, which must be an integer. Therefore, the measurement frequencies supported would be 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, and 100 Hz. The unprompted output rate allowed is 10, 20, 50, and 100 Hz.
-
The CSAT3A, CSAT3AH, CSAT3B, and CSAT3BH—like other sonic anemometers—measure wind speed along the sonic path using ultrasonic signals. If the salt spray blocks the sonic path, the sonic anemometer will not be able to make measurements. The same is true if a thick layer of salt is deposited on the transducer faces.
-
No. The sonic anemometer does not report time with the wind measurements. A time stamp will be assigned to the wind data by the data-acquisition system—either a data logger or a PC.
-
Yes. If the matching layer is damaged or missing, return the sonic anemometer to the factory for repair. Follow the steps listed on our Repair and Calibration page to request a return material authorization (RMA) number.
-
The CSAT3A, CSAT3AH, CSAT3B, and CSAT3BH are calibrated over temperature for the effects of transducer delays on the wind speed, and to a lesser extent, for the speed of sound measurements.
There is no NIST-traceable standard for ultrasonic anemometers.
-
The sonic anemometer measures three-dimensional wind in a right-handed Cartesian coordinate system. From these measurements, use trigonometry to compute the wind flow angle, horizontal angle, and wind speed.

Data Logger Considerations
The A100LK uses one pulse count channel on the data logger.
Programming
The A100LK is read by the PulseCount Instruction in CRBasic and by Instruction 3 (Pulse Count) in Edlog. Wind speed measurements can be taken and processed with any of the data loggers.
