CB-50 Data Buoy Overview


The CB-50 Data Buoy is an ultra-portable real-time system for short-term or seasonal monitoring of dredging projects, industrial spills, natural disasters, and other emergency response situations. It is designed to accommodate the NexSens X2-SDL submersible data logger for quick deployment of real-time monitoring with a range of compatible sensors.

Key Components and Definitions

Buoy Hull – Constructed of cross-linked polyethylene foam with a durable polymer outer layer and rugged stainless steel frame providing a net buoyancy of 50 lb (23 kg).

Data Well – The center hole of the hull designed specifically to accommodate the X2-SDL submersible data logger.

Tower – The top of the CB-50 is covered with a removable foam tower with top plate which is secured by a set of three eye nuts. This protects the X2-SDL logger while still allowing for wireless transmission, and the top plate allows for mounting of topside instruments like the M550 solar marine light for nighttime visibility.

Buoy Frame – The skeleton of the buoy is comprised of 316 stainless steel with three topside lifting eyes and one subsurface mooring eye for single-point moorings. The frame supports attachment of an optional instrument cage for secure connection of subsurface sensors, battery packs and additional ballast weight for stability.
