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 instrument deployment pipes and custom
sensor mounts.
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 CB-A05 battery harnesses and an X2-CB or
X2-CBMC data logger. The X2-CB has five UW sensor ports, and waterproof sensor connection is
achieved by factory installation of fully-sealed UW connectors 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.

For users supplying their own electronics, the CB-650 is delivered as an open platform with empty data
well or with battery only. A data well top plate can be supplied in one of three ways:
1. A standard CB-PTL Pass Through Lid for passing of instrument cables through gland fittings
2. A CB-PTL lid with UW8-BULK sensor bulkhead cable assemblies (alternative version with marine
wet-mate connectors available)
3. A blank lid with only UW6-BULK power cable assembly and vent that users may drill their own
holes and install connectors into
Solar Tower – Three 32W solar panels on the solar tower capture sunlight from any direction and
charge batteries located inside the data well. The tower also supports the mounting of aan M650 solar
marine light for nighttime visibility. Aside from regular cleaning to ensure solar panels are unobstructed
from receiving maximum sunlight, there is little to no maintenance required. However, solar assemblies
may be function tested if any performance issue is suspected by placing in the sun and measuring
output on the UW-6 (6-pin) port plug.

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

CB-Series Data Buoy Planning & Precautions
Buoy deployments are usually complex operations that involve many elements including sensors, data
loggers, mounting hardware and mooring equipment. Careful planning is essential to the success of a
buoy project, not only for system operation and data collection but also to ensure the project personnel’s
safety and minimize the risk of damage to expensive system components. When planning a buoy
deployment, be sure to give careful consideration to the following aspects:
Buoy sizing and power budget – Buoys come in various physical sizes with differing batteries and
solar charging capacities. A buoy must be adequately sized to tolerate the site environmental conditions
while providing sufficient power for continuous system operation. A power budget should be calculated
to ensure the system can meet the demand for sensor measurements and data transmission.
Buoy ballast – Proper ballast of a buoy is critical to buoy stability when it is deployed in the water. Be
sure to review the ballast weight and stability guide when designing a buoy system. Some
experimentation may be required before final deployment.
Buoy mooring – Mooring systems come in many forms depending on the location, water depth, and
environmental conditions to which a buoy will be exposed. As a starting point, the mooring data buoys
guide provides an overview of common mooring strategies. However, NexSens does not endorse any
particular mooring strategy, and systems should be designed and executed based on careful
consideration and local knowledge of the deployment site.
Electrical connections – Many NexSens buoy systems utilize UW connectors for connection of power
and sensor cables. Data loggers such as the X2-CB have UW receptacle ports to receive sensor cables
fitted with UW plug connectors. UW connectors provide a double O-ring seal, with one O-ring inside the
receptacle and one around the plug. In order to ensure waterproof connection, check the following each
time a UW connection is made:
1. The O-ring inside the receptacle is present (has not fallen out)
2. The receptacle and plug are clean, dry and free of debris
3. The O-ring on the plug is lightly greased
4. Connection is tight, secure and fully seated
5. Unused receptacle ports are fitted with UW port plugs
Connections may be periodically inspected and maintained with O-ring grease, at a minimum before
each buoy deployment.
CB-Series data buoys contain a waterproof data well constructed of stainless steel where batteries are
mounted. Whenever installing or maintaining battery systems, use caution to avoid short-circuiting of
battery poles to the metal walls of the data well. Gloves and tools with rubber grips are recommended,
and any exposed connections should always be covered with electrical tape or other suitable coverings.
Safe deployment – Above all else, safety is the most critical consideration to take during the planning of
a buoy deployment. Any time a buoy system is deployed, there are countless hazards, including, but not
7
limited to, working on/near water and lifting of heavy equipment. Important factors to consider for
personnel safety are:
Use of safety equipment (i.e., life jackets, gloves, steel toed boots, etc.,)
Proper lifting and mooring techniques
Awareness of on-site and surrounding weather conditions and advisories
Despite careful planning, unforeseen situations are always still a possibility. Buoy deployments are an
at-risk operation, and the user assumes liability for any injury or damages that may occur.

2. Buoy Assembly
Using NexSens Electronics in CB-Series Data Buoys
Although users may provide their own electrical components including data loggers, modems and
batteries, many CB-Series data buoys are delivered as complete, plug-and-play system packages with a
NexSens data logger as the central component of the system.
Data Loggers
NexSens offers four different data logging systems for buoy deployment, all of which are based on the
central processing unit of the X2 environmental data logger:
1. X2-SDL Submersible Data Logger – fully submersible unit designed for standalone operation or
installed in the CB-50 platform
2. X2-SDLMC Submersible Data Logger – fully submersible unit with topside wet-mate sensor
connectors for standalone operation or installed in the CB-25 platform
3. X2-CB Buoy-Mounted Data Logger – waterproof, lid-mounted package for integration on CB-
Series data buoys with data well and solar charging (model CB-150 and larger)
4. X2-CBMC Buoy-Mounted Data Logger – lid-mounted package with wet-mate connectors for use
on CB-Series data buoys in challenging environments such as offshore, typical on model CB-650
and larger
Reference the Data Loggers section of the NexSens Knowledge Base for resources including Quick
Start and User Guides to install, configure and operate NexSens data loggers with CB-Series data
buoys. Data logger user guides include detailed instructions on interfacing with sensors and setting up
transmission of data to the WQData LIVE web datacenter.

Battery Packs
X2-SDL and X2-SDLMC data loggers rely on internal batteries to supply power. X2-CB and X2-CBMC
data loggers are designed for use on CB-Series data buoys with solar charging (model CB-150 and
larger). These buoys have a data well for installation of battery packs, and the data logger serves as the
top plate to provide a waterproof seal on the data well.
NexSens offers two standard types of battery harnesses, which include sealed lead acid (SLA) batteries,
solar regulator, mounting bracket and data logger connection cable pigtail (UW-6 connector):
1. CB-A01-2 – contains two 8.5 A-hr batteries (CB-150 only)
2. CB-A05-x – contains one to four 28 A-Hr batteries (depending on buoy capacity – see table below)
The following table shows what battery harness models each CB-Series data buoy model has capacity
for in the data well. However, what model is selected should be based on a complete power budget
analysis that includes system power demand, solar charge capacity (panel size) and available sunlight
based on deployment location to aid in determining how much reserve battery power is needed.
