The NexSens buoy instrument cage attaches to the bottom of CB-Series buoys for water sensor deployments while simultaneously lowering the center of gravity and increasing stability. Model number CAGE is 39″ (99 cm) in length and is normally used with the CB-50, CB-150, CB-250, and CB-450 buoys. It is an optional accessory for the CB-50 […]
The NexSens CB-PTL Pass-Through Lid is used on NexSens CB-Series data buoys for custom integrations of user-supplied electronics. NexSens CB-Series data buoys with CB-PTL pass-through lids have optional bulkhead accessories for providing power, sensor connections, and telemetry to internal electronics. The pass-through lid includes (6) ports for sensor cables, a solar tower connection port, and […]
Sacrificial zinc anodes are recommended for use on CB-Series data buoys any time they will be used in saltwater environments. This helps to prevent corrosion on the stainless steel frame, as zinc is a more active metal that will be consumed while protecting the stainless steel. NexSens Sacrificial Anodes Anodes sourced from NexSens are sized specifically […]
The NexSens M550 Solar Marine Light is a common accessory added to NexSens CB-Series data buoys up to and including the CB-450. Depending on the configuration, it has a 1-3 nautical mile range and is normally delivered with flange mount hardware, yellow color and default 15 flash/minute pattern (Model M550-F-Y). Installation While it typically […]
Ballast weight may be needed to prevent overturning a CB-series buoy system and ensure stability in the water. The center of gravity of NexSens CB-Series buoys is near the water surface without instruments connected. Therefore, any top-side weight added above the water’s surface (e.g., sensors, sensor mounts) must be appropriately counterbalanced by ballast weight below the […]
The following article provides information on the proper settings required for communication between a Nortek AWAC Current Profiler and an X2 data logger. Advanced information describes the NMEA messages and parameters recorded from the sensor by the X2 and includes troubleshooting procedures for common error codes. Nortek AWAC Current Profiler Setting Requirements […]
Real-Time Water Quality Measurements The Sea-Bird Scientific HydroCAT CTD is ideally suited for extended deployments in remote, biologically rich environments to measure conductivity, temperature, pressure, and optical dissolved oxygen. The sensor is compatible with NexSens X-Series data loggers using the SDI-12 communication protocol and sensor interface. Parameter data is transmitted, in real-time, at a user-specified […]
The TriOS NICO UV Nitrate Sensor is an in-situ UV photometer that measures nitrate in lakes/rivers, drinking water, and wastewater applications. Nitrate is measured using the common principles of UV optical absorption utilized in laboratories worldwide. The sensor is compatible with the X2 data logger over the RS-485 sensor interface using the Modbus-RTU communication protocol. […]
The table below indicates the minimum recommended buoy ballast weights for each CB-Series data buoy, assuming no additional topside weight and calm environmental conditions. Included instrument cages mounted to the buoy frame helps stabilize the buoy and provides a deeper location for mounting additional weight. The small model instrument cage (10 lbs.) is included with […]
The following buoy storage requirements are required when storing a CB-Series data buoy with an X2-CB data logger: Storage Requirements Store the buoy in a dry environment that is kept above freezing. A climate-controlled location may be necessary. Extremely cold temperatures can negatively impact the performance of the batteries. Cold or excessively fluctuating storage temperatures […]
