CB-450 Data Buoy CB-450 Data Buoy

CB-450 Data Buoy

The CB-450 data buoy is ideally suited for dredge turbidity monitoring, temperature profiling, dissolved oxygen monitoring, limnology research, and weather monitoring on inland lakes.

Features

Versatile

The CB-450 is light enough to be deployed from most small boats, yet it offers adequate power and charging for rigorous instrument sampling and data transmission.

Q&A

How can I ensure buoy stability?
down-arrow
Buoy stability is dependent on a number of factors including instruments attached, mooring design, water currents, and regional weather conditions. It is recommended to examine the buoy upon deployment, adding ballast weight and adjusting the mooring as needed. Given that each deployment is unique, be sure to communicate with NexSens application engineers for optimal stability.
Under what conditions would I need to remove the CB-450 data buoy?
down-arrow
Freezing and periodic maintenance are the two most common reasons to remove a buoy from the water. A large number of buoy deployments are seasonal, so customers will commonly remove the buoy in the fall and redeploy in the spring. For year-round buoy deployments, NexSens recommends pulling the buoy at least once for cleaning and maintenance inspection. The potential for large storms and river debris flows are also good reasons to pull a buoy in order to prevent any ensuing damage. NexSens recommends integrating a GPS in situations where debris loads or other circumstances have the potential to move the buoy, like in a river or coastal setting.
How do I know if I need an anti-rotation collar on the instrument cage?
down-arrow
An anti-rotation collar is not necessary if the buoy is deployed on two point mooring and no instruments are attached to cage. Anti-rotation collars are recommended for single point moorings or when instruments are attached to the cage. This provides an added strength member and prevents the potential for cable tangling.
