Campbell Scientific Met One 034B-L Windset Specification

The Campbell Scientific Met One 034B-L Windset is a robust and reliable anemometer designed for precise wind speed and direction measurement. It features a lightweight, four-blade propeller that efficiently measures wind speed with a range of 0 to 75 meters per second and an accuracy of ±0.3 m/s up to 15 m/s. The wind direction is gauged using a durable, stainless-steel vane that offers a range of 0 to 360 degrees and an accuracy of ±3 degrees. The unit operates efficiently in a temperature range of -50°C to +50°C, making it suitable for diverse environmental conditions.

The windset is constructed from corrosion-resistant materials, ensuring long-term durability even in harsh weather conditions. It is equipped with a cable length option, denoted by the 'L' in the model name, which allows users to select a cable length that suits their installation requirements. The 034B-L is compatible with Campbell Scientific dataloggers, which facilitate data collection and monitoring, providing users with comprehensive wind data analysis capabilities.

Installation of the Met One 034B-L is straightforward, with the unit designed to be mounted on a vertical pipe with an outer diameter of 1.0 to 1.75 inches. The windset requires a 12 VDC power supply and consumes minimal power, making it an energy-efficient choice for continuous operation. Its analog output signal is easily interpretable by a wide range of data acquisition systems, ensuring seamless integration into existing meteorological setups.

Overall, the Campbell Scientific Met One 034B-L Windset is an ideal choice for meteorological stations, environmental research, and any application requiring accurate wind measurements. Its combination of precision, durability, and ease of integration makes it a valuable tool for professionals in the field.

Campbell Scientific Met One 034B-L Windset F.A.Q.

How do I properly install the Met One 034B-L Windset?

To install the Met One 034B-L, mount the anemometer and vane on a mast with the supplied u-bolts. Ensure the north alignment arrow is pointing true north. Connect the sensor to your data logger using the supplied cables, following the wiring diagram in the manual.

What is the recommended maintenance schedule for the 034B-L Windset?

Regular maintenance should be performed every six months. This includes checking for loose connections, inspecting the cable for wear, cleaning the sensor components, and verifying calibration. Lubricate the bearings if necessary.

How can I troubleshoot inaccurate wind speed readings?

First, check for obstructions near the anemometer. Inspect the sensor and cable for damage. Verify that the data logger is configured correctly. If the issue persists, check the calibration and consider replacing the bearings.

What should I do if the wind vane does not rotate freely?

Inspect for physical obstructions or debris around the vane. Clean the pivot point and ensure it is free of dirt. If the problem continues, check for damage to the vane or replace the bearings.

Can the Met One 034B-L Windset be used in extreme weather conditions?

The 034B-L is designed to operate in a wide range of environmental conditions. However, it should be inspected after extreme weather events to ensure it remains in good working condition.

How do I calibrate the Met One 034B-L Windset?

Calibration involves comparing the windset's output with a known standard. Adjustments can be made via the data logger's settings. For detailed instructions, refer to the calibration section in the user manual or contact technical support.

Is it possible to replace the cable on the 034B-L Windset?

Yes, the cable can be replaced. To do so, disconnect the existing cable from the sensor and data logger, then install the new cable following the wiring instructions in the manual. Ensure all connections are secure.

What are the common causes of erratic wind direction readings?

Erratic readings can result from electrical interference, loose connections, or mechanical obstructions. Check the wiring and ensure the vane is free of debris. Verify that the data logger settings match the sensor configuration.

How do I clean the Met One 034B-L Windset?

Use a soft cloth and mild detergent to clean the anemometer and vane. Avoid using harsh chemicals or abrasive materials. Ensure the components are dry before reassembling. Regular cleaning helps maintain optimal performance.

What should I do if the anemometer cups are damaged?

If the cups are damaged, they should be replaced to ensure accurate wind speed measurements. Contact Campbell Scientific or an authorized distributor for replacement parts. Follow the instructions provided for installation.
