CB-Series Data Buoy Planning & Precautions
Buoy deployments are usually complex operations that involve many elements including sensors, data loggers, mounting hardware, and mooring equipment. Careful planning and precautions are essential to the success of a buoy project, not only for system operation and data collection but also to ensure the safety of project personnel and minimize the risk of damage to […]
CB-Series Data Buoy Instrument Cage Installation
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 […]
M550 Beacon for CB-Series Data Buoys
The NexSens M550 Solar Marine Light is a common accessory added to NexSens 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 comes […]
Sea-Bird Scientific HydroCAT CTD X-Series Integration Guide
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 […]
TriOS NICO UV Nitrate Sensor: X2 Integration Guide
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. […]
X-Series Logger Supported Sensors
All X-Series data logger systems incorporate multiple waterproof UW sensor ports with available sensor interfaces including SDI-12, RS-485 and RS-232. This allows for compatibility with a wide range of sensors and data transmission protocols such as SDI-12, NMEA0183 and Modbus. Many compatible sensors can be automatically detected by X-Series loggers, while others require custom configurations […]
UW-6 Power Bulkhead Connector Assembly Wiring
CB-Series Buoys supplied with a CB-PTL Pass-Through Lid for integration of user-supplied electronics include a UW-6 power bulkhead connector (UW6-BULK) port on the lid. The UW6-BULK connects to the solar tower on the outside of the buoy and has bare wires with Molex connector on the inside of the data well. Information regarding the port […]
Lighter Buoys Mean Quicker, In-House Responses
