MB-300 Data Buoy

The MB-300 buoy platform with 300 lb. buoyancy is ideal for deploying temperature strings, multi-parameter sondes and other monitoring instruments in small reservoirs, lakes, rivers, streams, and protected coastal waters.

NexSens MB-300 and MB-500 Data Buoys are designed specifically for offshore water monitoring systems. The floating platform supports both topside and subsurface environmental monitoring sensors with options for spread spectrum radio, cellular, and satellite data transmission to shore. Temperature strings, multi-parameter sondes, Doppler current meters, weather stations, and other monitoring instruments can be quickly deployed in reservoirs, lakes, rivers, streams, and protected coastal waters.

The buoys are constructed of an inner core of cross-linked polyethylene foam with a tough polymer skin. A 6" diameter PVC pipe passes through the center of the buoy for quick deployment of subsurface instruments. On the topside, a hinge-mount aluminum tower offers quick access to instrumentation for calibration and maintenance. Three topside cutouts accommodate NexSens SP5 solar power packs, which include a 5-watt solar panel, charge regulator, and 8.5 A-Hr SLA battery housed in a watertight enclosure. Top and bottom-mounted stainless steel eye-nuts support mooring lines and lifting rigs for quick deployment.

The 300 lb. and 500 lb. buoyancy buoys are designed to accommodate NexSens SDL500 submersible data loggers. The SDL500 is configured with five sensor ports for connection to industry-standard digital and analog sensor interfaces, including RS-485, SDI-12, 1-wire temp string, 0-2.5V, pulse count, and more. Each sensor port offers a UW receptacle with double o-ring seal for a reliable waterproof connection. NexSens iChart Software is a Windows-based program for interfacing both locally (direct-connect) and remotely (through telemetry) to a single Data Buoy or network of Data Buoys.
