NexSens CB-150 Data Buoy

The CB-150 data buoy is designed for smaller water bodies, portable or short-term deployments, and applications requiring compact or low-power sensors

Category: Tag:



With an overall 24-inch diameter by 63-inch height, the CB-150 can be deployed quickly and easily from a small boat. Fully configured systems typically weigh less than 100 lbs.




Three integrated solar panels are angled and evenly spaced around the buoy to capture sunlight from any direction and provide adequate battery charging.


Data Well:


A 10-inch diameter by 12-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 2-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 2-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, 3rd 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-150 is designed for years of service.
