NexSens CB-450 Data Buoy
The NexSens CB-450 Data Buoy is designed for deployment in lakes, rivers, coastal waters, harbors, estuaries and other freshwater or marine environments where environmental data collection is planned. The floating platform accommodates both topside and subsurface environmental monitoring sensors including weather stations, wave sensors, thermistor strings, multi-parameter sondes, Doppler current profilers and other monitoring instruments.
First Time Setup
1.1 What’s Included
The CB-450 includes the following accessories and spare parts for deployment.
1.2 Common Accessories
The following are common accessories to the CB-450 Data Buoy for power, mooring and ballast, and sensor mounts. Additionally, this list includes a recommended beacon and the optimal data logger for the CB-450, the X2-CB Buoy Mounted Data Logger.
1.3 X2-CB User Guide
The X2-CB is an all-in-one environmental data logger specifically designed for use with a NexSens CB-Series data buoy. It automatically recognizes sensors and sends data to the web via cellular, radio, or satellite telemetry. If an X2-CB was purchased with a CB-450, follow the link below to learn more about the X2-CB data logger.
2.1 Instrument Cage Attachment
Always follow safe marine and boating practices.
3.2 Ballast Weight and Stability
To prevent overturning and ensure stability, additional ballast weight may be needed.
4.1 Mooring Options
When to Use
When to Use
Important: This section contains only general information on the available mooring options for CB-450 data buoys. To develop an effective mooring strategy, a variety of application-specific criteria (water level fluctuations, currents and wave action, debris loads, etc.) must be thoroughly reviewed prior to deployment. NexSens does not endorse any particular mooring strategy for any specific application.

Proper storage of a buoy system is essential to maintain the integrity of its electrical and physical components. Follow the link below to learn the appropriate storage guidelines for the CB-450 Data Buoy, along with common errors to avoid.
5.5 Battery Check
Use a DC multimeter and measure the voltage between pins 3 (V+) and 4 (GND) on the SOLAR port.
Healthy SLA battery voltage is 12.0-14.9V.
5.6 Battery Replacement
The 12V sealed lead acid batteries installed in the data well of CB-Series buoys may require replacement if their charge falls below ~10V or every 3-5 years as their integrity declines with age. This article highlights the basic steps required to replace the A05 12V 28 A-Hr battery commonly equipped in quantities of 1 to 3 on the NexSens CB-450, CB-650, CB-950, and CB-1250 data buoys.
Follow the link below for a step by step process on replacing a CB-Series battery.
6.1 Solar Tower Testing
Three 13W diode-protected panels allow for solar charging when the buoy is facing any direction. As a precaution, these panels are diode protected in the instance that they are not receiving direct sunlight. When configured with factory installed batteries, a solar regulator is included in the data well. Otherwise, a solar regulator is required from an outside source.
Solar panel voltage output between pin 1 and pin 3 of the UW-6 SOLAR plug will vary between 8-20V depending on the available sunlight.
Connect the leads of a DC voltmeter to pin 1 and pin 3 to confirm the panels are producing the expected voltage.
