X2-CB Buoy-Mounted Data Logger
The X2-CB includes all the features of the flagship X2 data logger in a lid-mounted package designed for integration on CB-Series data buoys.
A smartphone, tablet, or laptop connects by Wi-Fi to access sensor data and view or change settings. No application-specific hardware or software is required. Works within an existing Wi-Fi network or as a direct link from the X2-CB to the device.
All connections are made with a simple waterproof thread-in connector. This removes the complications and errors associated with connecting individual wires.
When communicating within a Wi-Fi network or connecting via remote telemetry, measurement data streams directly to the WQData LIVE web datacenter.
Wi-Fi provides short range and local connectivity. Remote options include radio, cellular, and satellite communications.
SensorBUS technology incorporates industry standard SDI-12, RS-485 and RS232 interfaces in a single watertight cable. Smart sensors are available for most environmental measurements.
Buoy Mount Housing
The X2-CB is sealed in a watertight PVC enclosure mounted directly to the bottom of a NexSens CB-Series buoy's 316 stainless steel data well top plate. With (5) integrated sensor ports, a vent, an antenna port, and a communication/power port, the X2-CB provides ultimate flexibility and ease of access to all connections.

To clean up environmental contaminants released in its waters going back to the 1960s, the San Diego Regional Water Control Board ordered dredging actions to begin in San Diego Bay in March 2012. The plan of approach was clear: A section of the bay, called the South Site, would be dredged first, and then a second phase of the work would dredge the North Site. Organizations involved in the work […]Read More →
Keeping an eye on the health of Lake Erie is a big job, involving a lot of agencies, organizations and monitoring equipment. The collective efforts help make the lake one of the best studied in the world, along with the other four Great Lakes. Buoy networks in Lake Erie are important to those efforts, as they help scientists around it keep tabs on measurements influencing the lake and its health. […]Read More →
With Lake Erie’s algal bloom problem persisting in its western basin, state officials and researchers are working to expand monitoring capabilities there. Many of those are supported by networks of buoys that collect readings from advanced sensors measuring water quality. The issue of most concern is maintaining the safety of drinking water for those living near the lake. In Sandusky Bay, the problem is no different. But there is a […]Read More →
