Campbell Scientific CA27 Anemometer Specification

The Campbell Scientific CA27 Anemometer is a precise meteorological instrument designed for accurate wind speed measurements in various environmental conditions. This anemometer features a three-cup rotor assembly which is engineered to enhance sensitivity and durability. The rotor is constructed from robust materials, ensuring reliable performance in harsh weather conditions. The CA27 employs a magnet and reed switch mechanism, generating a pulse output that is directly proportional to wind speed. This design allows for straightforward integration with data loggers and other data acquisition systems, making it a versatile choice for meteorological and environmental monitoring applications.

The CA27 has a measurement range typically spanning from 1 to 90 meters per second, with a starting threshold of approximately 0.5 meters per second, ensuring responsiveness to low wind speeds. The anemometer exhibits a high degree of accuracy, with a standard deviation error within 1% of the measured value under most conditions. Its compact design facilitates easy installation on masts and other mounting structures, with compatibility for both portable and permanent setups. The CA27 is also engineered for low-maintenance operation, with its sealed bearings reducing the need for frequent servicing.

Constructed to withstand extreme temperatures and environmental challenges, the CA27 is suitable for deployment in diverse climates, from arctic to desert environments. The device's robust design minimizes the risk of mechanical failure, ensuring consistent performance over extended periods. Additionally, the CA27 can be paired with a variety of Campbell Scientific accessories and software solutions, enabling comprehensive data analysis and reporting capabilities. This makes it an ideal choice for researchers and professionals seeking reliable and precise wind measurement solutions.

Campbell Scientific CA27 Anemometer F.A.Q.

How do I properly install the Campbell Scientific CA27 Anemometer?

To install the CA27 Anemometer, first choose a location clear of obstructions. Secure the anemometer to a mast or pole using the included mounting hardware. Ensure it is level and oriented correctly according to the user manual. Connect the signal cable to the appropriate data logger inputs.

What maintenance is required for the CA27 Anemometer?

Regular maintenance for the CA27 includes checking the bearings for wear, cleaning the sensor to remove dirt or debris, and inspecting cables and connections for damage. It is recommended to perform these checks annually.

How can I troubleshoot if the CA27 Anemometer is not recording data?

First, verify all cable connections are secure. Check the data logger's configuration to ensure it recognizes the CA27. Test the anemometer's output with a multimeter to confirm it is generating a signal. Replace any damaged cables or components.

Can the CA27 Anemometer be used in extreme weather conditions?

Yes, the CA27 is designed for harsh weather. However, extremely high winds or ice accumulation can affect performance. It is advisable to regularly inspect and maintain the anemometer during such conditions.

What is the optimal height for installing the CA27 Anemometer?

The optimal height for installation varies based on the intended application. For standard meteorological use, a height of 10 meters above ground level is recommended to avoid ground interference.

How do I calibrate the CA27 Anemometer?

Calibration of the CA27 typically requires comparison against a known standard or reference anemometer. Follow the calibration procedure outlined in the user manual, which may involve adjusting the data logger settings.

What data logger models are compatible with the CA27 Anemometer?

The CA27 Anemometer is compatible with most Campbell Scientific data loggers, including the CR1000, CR3000, and CR6 series. Ensure the logger supports the anemometer's output signal type.

How do I clean the CA27 Anemometer without damaging it?

Use a soft, damp cloth to gently wipe the anemometer's surfaces. Avoid using harsh chemicals or abrasive materials that could damage the sensor. Ensure the anemometer is completely dry before reinstallation.

What should I do if the CA27 Anemometer's bearings are noisy?

Noisy bearings indicate wear and may need replacement. Contact Campbell Scientific for replacement parts and follow the bearing replacement procedure in the user manual to avoid further damage.

How can I extend the life of my CA27 Anemometer?

To extend the life of your CA27 Anemometer, perform regular maintenance, protect it from physical damage, and ensure it is installed in an optimal, unobstructed location. Regularly update your data logger's firmware to maintain compatibility.
