Campbell Scientific A100LK Anemometer Specification

The Campbell Scientific A100LK Anemometer is a precise and reliable instrument designed for measuring wind speed. Engineered with a lightweight, robust construction, it is suitable for various meteorological applications. The anemometer features a three-cup rotor system, optimized for minimal friction, which ensures accurate wind speed measurements across a range from 0 to 75 meters per second. This design allows for exceptional sensitivity and a low threshold of starting speed, making it effective in detecting even slight breezes. The A100LK is equipped with a high-resolution optical encoder that translates the rotational speed of the cups into an electrical signal, providing a digital pulse output that is easily integrated with data loggers or other recording devices.

The instrument is housed in anodized aluminum and stainless steel, offering durability and resistance to harsh environmental conditions, ensuring longevity in field deployments. It operates effectively in a wide temperature range from -30°C to +70°C, making it versatile for both extremities of weather conditions. The A100LK requires a power supply of 5 V to 24 V DC, consuming minimal power, which is advantageous for remote installations. Its compact design, with a height of 220 mm and a rotor diameter of 126 mm, allows for easy transportation and installation.

Overall, the Campbell Scientific A100LK Anemometer combines robust construction with high precision and efficiency, making it an ideal choice for detailed wind analysis in diverse applications, including research, agriculture, and renewable energy sectors.

Campbell Scientific A100LK Anemometer F.A.Q.

What is the recommended procedure for installing the Campbell Scientific A100LK Anemometer?

To install the A100LK Anemometer, mount it on a stable, vertical mast away from obstructions. Ensure the sensor is level and securely fastened. Connect the sensor cable to the data logger, ensuring all connections are weatherproof.

How can I troubleshoot if the A100LK Anemometer is not providing any data?

First, check all cable connections for security and integrity. Ensure the data logger is powered and properly configured. Verify the sensor is not physically obstructed and the cup assembly is free to rotate.

What maintenance is required to keep the A100LK Anemometer functioning optimally?

Regularly inspect the anemometer for dirt, debris, or ice accumulation. Check the bearings for wear and ensure the cups spin freely. Clean the sensor with mild detergent and water if necessary.

How can I calibrate the Campbell Scientific A100LK Anemometer?

Calibration should be conducted in a wind tunnel or controlled environment. Compare the output of the A100LK with a reference anemometer and adjust the calibration factor in the data logger as needed.

What should I do if the A100LK Anemometer is providing erratic wind speed readings?

Check for loose or corroded connections and ensure the cable is intact. Examine the anemometer for physical damage or obstruction of the cups. Verify the data logger settings for correct configuration.

Can the A100LK Anemometer be used in extreme weather conditions?

Yes, the A100LK is designed for harsh environments, but it is important to ensure it is mounted securely and checked regularly for ice or debris buildup that could affect performance.

What data output can I expect from the Campbell Scientific A100LK Anemometer?

The A100LK provides an AC sine wave output with a frequency proportional to wind speed. This can be converted by a data logger into wind speed measurements.

How can I protect the A100LK Anemometer from lightning strikes?

Install surge protection devices and ensure the anemometer mast is properly grounded. Use shielded cables and maintain a safe distance from large metallic structures.

What should I do if the anemometer cups are damaged or missing?

Replace the cup assembly immediately to ensure accurate wind speed measurements. Contact Campbell Scientific for replacement parts or authorized service providers.

How do I integrate the A100LK Anemometer with a Campbell Scientific data logger?

Connect the anemometer's output cable to the appropriate channel on the data logger. Configure the logger to interpret the frequency signal as wind speed using the manufacturer's guidelines.
