CB-650 Data Buoy Overview
The CB-650 data buoy offers a compact platform with convenient tower mounting for met sensors,
navigation lights, and radar reflectors. It is designed for deployment in 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 650 lb (295 kg). Three 4” 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-650 model, the data well has a 10.3” (26.2
cm) diameter and 21.5″ (54.6 cm) height.
For complete NexSens systems, the data well is fitted with
or
data logger. The X2-CB has five UW sensor ports, and waterproof sensor connection is
achieved by factory installation of
onto sensor cables. The X2-CBMC has
five sensor ports with wet-mate marine connectors for enhanced performance in extreme conditions.
Both loggers support the common standards such as SDI-12, RS-232 and RS-485 with the internal X2
electronics.
