•  Self-powered data logging buoy 
  • Wi-Fi, radio, cellular or satellite telemetry 
  • Supports a variety of environmental sensors 
  • Accommodates most environmental data loggers 
  • Rugged polymer-coated foam hull 

The NexSens CB-150 Data Buoy is designed for deployment in lakes, rivers, coastal waters, harbors, estuaries and other freshwater or marine environments. The floating platform supports both topside and subsurface environmental monitoring sensors including weather stations, wave sensors, thermistor strings, multi-parameter sondes, Doppler current profilers and other monitoring instruments. The buoy is constructed of an inner core of cross-linked polyethylene foam with a tough polyurea skin. A topside 13” tall stainless steel tower includes three 6-watt 12 VDC solar panels, and a center 10” ID x 13.5” tall data well accommodates batteries, data loggers, sensors and more. Three 2” passthrough holes with female NPT bottom threads allow for quick connection of instrument deployment pipes and custom sensor mounts. The stainless steel frame supports both single point and multi-point moorings.

The CB-150 Data Buoy is optimized for use with NexSens data loggers. Wireless telemetry options include Wi-Fi, spread spectrum radio, cellular and Iridium satellite. Compatible digital and analog sensor interfaces include RS-232, RS-485, SDI-12, VDC, mA and pulse count. The top of the instrument well includes 8 pass-through ports for power and sensor interface. Each port offers a UW receptacle with double O-ring seal for a reliable waterproof connection.
