CB-250 Data Buoy Overview
The CB-250 data buoy strikes a balance between compact and easy to deploy, yet buoyant and
powerful enough to be deployed in larger water bodies including lakes, rivers, coastal waters, harbors,
estuaries and other freshwater or marine environments. Like all solar-powered NexSens CB-Series data
buoys, it is a highly customizable platform that may be configured with NexSens or user-supplied
electronics. It supports a wide variety of topside and subsurface sensors and measurement instruments.
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 250 lb (114 kg). Three 2” passthrough holes
with female NPT bottom threads allow for quick connection of
Data Well – The waterproof compartment located in the center of the buoy hull for placement of system
electronics such as batteries and data loggers. On the CB-250 model, the data well has a 10.3” (26.2
cm) diameter and 19.5″ (49.5 cm) height.
For complete NexSens systems, the data well is fitted with
battery harnesses and
, which includes five sensor ports with
supporting
common standards such as SDI-12, RS-232 and RS-485. Waterproof sensor connection is achieved by
factory installation of
onto sensor cables.
