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 […]
The Nortek Signature Series sensor is a high-performance acoustic doppler current profiler (ADCPs) used for measuring wave current velocity (via multiple cells), current direction, water temperature, and pressure. Configure Deployment Template Nortek’s Signature Deployment software must be used to configure a Signature Series sensor for use with an X2 Data Logger. Download and install […]
Use a DC volt/multimeter to verify the battery voltage of a CB-Series data buoy on the UW-6 (6-pin) SOLAR port on the data well top plate. This method works for both user-supplied battery systems with CB-PTL pass-through lid and NexSens-supplied CB-A01 and CB-A05 SLA battery systems. Measure the voltage between pins 3 (V+) and 4 […]
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 […]
Flood warning systems are designed to help improve warning of flood and weather events. These systems help give early warning for the public and local governments based on local measurements in real time.
Dredging done correctly doesn’t hurt water quality, and can yield positive environmental results. However, ensuring these good results demands monitoring for contaminant release, sediment resuspension, and other water quality issues.
Coastal buoy monitoring systems, which are subjected to harsh and unpredictable weather and other forces, are simple to use and promise highly accurate performance despite punishing conditions.
Real-Time Water Temperature Measurements The NexSens TS210 Thermistor String provides high-precision temperature measurements for profiling in lakes, streams and coastal waters. It features an integral titanium thermistor secured and epoxied in a protective housing for underwater deployments. TS210 strings integrate with NexSens X-Series data loggers using the Modbus communication protocol and RS-485 sensor interface. A […]
Real-Time Water Temperature Measurements The NexSens T-Node FR water temperature sensor utilizes an integral titanium thermistor secured in a protective housing for underwater deployments in fresh, brackish or seawater. T-Node FR sensors integrate with NexSens X-Series data loggers using the Modbus communication protocol and RS-485 sensor interface. A pre-defined script on NexSens X-Series data loggers […]
