  • Page 11: Performing A Measurement System Power Budget

    To aid with this, NexSens has developed a power budget tool which can quickly estimate the expected power performance of systems using the most common NexSens buoy platforms, data logger configurations, and commonly integrated NexSens and third-party sensors for deployment locations throughout the world.
  • Page 12 The example below shows an Airmar 200WX-IPX7 weather station, NexSens T-Node FR temperature string with 10 nodes, Nortek Signature 1000 current profiler, and a YSI EXO3 sonde all on switch power. Select sensors from drop-down list.

  • Page 15 However, if an appropriate location does not appear to be available, it is recommended to contact NexSens as new locations can normally be added quickly upon request.

  • Page 17: Advanced Custom User Entry

    Advanced Custom User Entry Because flexibility for use with user-supplied loggers, batteries, sensors and other electronics is a basic design principle of NexSens CB-Series data buoys, the power budget calculator also facilitates user entry of data for all components. Besides just the Custom sensor data entry noted in step 3 above, the Custom User Entry tab supports input of user-supplied data loggers, solar panels, telemetry systems and battery packs, as well as solar insolation for the exact deployment location.

  • Page 18: Disclaimer

    Disclaimer The NexSens power budget calculator is intended as a helping tool for correct system design. It integrates efficiency factors and other conservative estimates of power consumption in order to provide a best possible approximation of system power performance and viability. However, real-world conditions may vary, and field testing is the only way to ensure that a system will perform adequately.

  • Page 89 Acceptable values will range from a slight negative percentage (effectively zero) up to ~50%. If a logger reports humidity greater than 50%, replace the desiccant bag inside X2-CB and inspect the enclosure seal.
