Data Logging

The X2-CB data logger replaces the standard pass-through data well lid for turnkey systems. Alternatively, 3rd party data loggers can be integrated by the user inside the data well.

Q&A

Do I need sacrificial anodes in any saltwater application?

Sacrificial zinc anodes are recommended for any buoy deployed in saltwater or brackish conditions. Sacrificial anodes prolong the life of the buoy and protect the stainless steel hardware and instrument cage from corrosion. Both the buoy frame and the instrument cage should have a sacrificial anode attached (2 per buoy). Check the anodes during each maintenance visit and replace when necessary, which is typically six months to one year depending on conditions.

Why is it called the CB-650 data buoy and why is it yellow?

CB stands for "Coastal Buoy". The number 650 denotes net buoyancy, the buoyant capacity of the buoy after hardware is installed. A safety yellow hull is a standard international practice and requirement of the U.S. Coast Guard to signify research buoys.

What applications require a radar reflector?

Radar reflectors are important in high traffic waterways to alert boats and vessels. While the lid on top of the hull has some radar reflecting qualities, adding a radar reflector will ensure radar visibility at any time. It is recommended for any offshore buoy to be fitted with a radar reflector and navigation light.

What is the difference between the CB-650, -950 and -1250?

In addition to buoyancy capability, the solar towers offer incrementally larger solar panels for projects with a heavier power load. The bigger the buoy, the more batteries can be stored in the data well for reserve power. The instrument hole diameters are 4 inches, 6 inches and 8 inches respectively in the three large buoy models.
