CB-150 Data Buo
Quick Start Guide
Instrument Cage Installation
- Use the provided bolt, lock washer, and castle nut to attach the cage to the buoy frame. See Figure 1.
Overview
Tighten firmly with a pair of 1-1/8 wrenches. Ensure to flatten the lock washer and align the bolt hole with a notch on the castle nut. See Figure 2.

- Data Well Dimensions: 10.3 (26.2 cm) inside diameter; 13.5 (34.2 cm) tall
Mooring Configurations
To develop an effective mooring strategy, a variety of application-specific criteria (water level fluctuations, currents, and wave action, debris loads, etc.) must be thoroughly reviewed prior to deployment. NexSens does not endorse any particular mooring strategy for any specific application. For more information on mooring configurations, follow the link provided: https://www.nexsens.com/cb150kb/mooring-configurations.htm
Safe Deployment
Warning: Always follow safe marine and boating practices. Heavy anchors, ballast weights, and chains require careful maneuvering. Small boats with limited lifting equipment and boat clutter can be unsafe. Care must be taken during deployment to maintain a clean and safe environment.
Ballast Weight & Stability
To prevent the overturning of a CB-150 buoy system and to ensure that it is stable in the water, additional ballast weight may be needed. The buoy’s center of gravity is near the water surface without instruments connected. Any weight added above the water surface must be appropriately counterbalanced by adding ballast weight below the surface. For more information regarding top- side and ballast weight, follow the link provided: https://www.nexsens.com/cb150kb/top-side-ballast-weight.htm The buoy data well is not rated for submersion, so proper ballast weight is critical to ensure that the buoy does not overturn, including when the buoy is subjected to additional loading (e.g. high wind/waves, periodic snow/ ice loads, etc.).
Saltwater Deployment
Sacrificial zinc anodes should be used whenever a buoy is deployed in a saltwater environment to prevent corrosion. These zinc anodes must be inspected and replaced as needed. For additional information, please reference the CB-150 Resource Library on the NexSens Knowledge Base. nexsens.com/cb150kb

Product Usage Instructions
- Attach the instrument cage to the buoy frame using the provided bolt, lock washer, and castle nut. See Instrument Cage Installation above for detailed instructions and Figures 1-2 for reference.
- Tighten the cage firmly with a pair of 1-1/8 wrenches.
- Place the cotter pin through the bolt hole and bend the long leg of the pin. See Figure 4 for reference.

Overview
The CB-150 data buoy is constructed of an inner core of cross-linked polyethylene foam with a polyurea coating that provides 150 lb. buoyancy. A stainless steel internal frame provides topside lifting eyes and subsurface mooring eyes for single- and multi-point mooring. An integrated data well accommodates internal batteries, which are recharged by (3) 10-watt solar panels mounted on the buoy tower. The data well lid is available as a NexSens X2-CB buoy-mounted data logger or as a standard lid with included pass-through fittings.
