NexSens CB-950 Data Buoy

The CB-950 offers sufficient power and sensor payload for demanding instruments including video cameras, ADCP’s and more

Category: Tag:



The platform integrates three 40-watt solar panels on the tower with space for up to three 28 A-Hr batteries in the data well.




The stainless steel tower includes a top mounting plate for solar marine light and radar reflector. Mounts are also available for weather sensors, video cameras and other topside instruments.


Data Well:


A 10-inch diameter by 26-inch tall data well provides a watertight housing for batteries, data loggers, sensors, and other hardware.




The data well lid provides pass-through connections for sensors, power, venting, and more. When integrated with the optional NexSens data logger and connectorized lid, the system is truly plug-and-play.


Top-to-Bottom Ports:


Three 6-inch pass-through ports allow for sensors to be mounted underwater while securely routing the cable. Instrument deployment pipes and custom sensor mounts attach to 6-inch NPT bottom threads.


Solar Beacon:


The optional solar marine light has a one to three nautical mile range and securely mounts to the buoy top plate for maximum visibility.


Data Logging:


The data well lid is pre-configured to accommodate the NexSens data logger. Alternatively, third party data loggers can be housed inside the data well.


Wireless Communication:


Waterproof telemetry modules securely mount to the buoy top plate. Communication options include radio-to-shore, cellular and Iridium satellite.


Built to Last:


Constructed of cross-linked polyethylene foam with a heavy polymer skin and an indestructible stainless steel frame, the CB-950 is designed for years of service.
