  • Page 15: 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 16 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. Figure 3: Select sensors from drop-down list.
  • Page 17 b. While the pre-populated sensor list is fairly extensive and frequently updated, it does not list all compatible sensors. In such cases, it is possible to enter up to four devices manually by selecting Custom 1/2/3/4 from the drop-down list. Figure 4: Custom sensor entry.
  • Page 18 c. Once selected, proceed to the Custom User Entry tab of the spreadsheet. Then, navigate to the Sensor Details section. Fill in the prompted information either using data from the device manufacturer or measured data during device testing. Figure 5: Custom sensor data entry.
  • Page 19 Note that some instrument types have a number of different configurations which may affect power performance. The predefined sensors in the drop-down list reflect a typical configuration and information provided by the manufacturer or NexSens bench testing where applicable. These therefore represent a best approximation based on available information.

  • Page 21: 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 additional inputs.

  • Page 22: Disclaimer

    Disclaimer The NexSens power budget calculator serves 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.

  • Page 31 a. An X2 cannot simultaneously connect to a mobile device and a local wireless network. Any mobile device connection to the X2 will prevent it from connecting to the local wireless network and contacting the WQData LIVE web datacenter. b. Due to the above, it is generally advisable to have the device ‘forget’ the X2’s network so that it does not auto-reconnect to it.

    These sensors are not commonly supported by the X2, but can be added through the creation of a user-defined script. The script is written in Lua and utilizes NexSens-created functions to simplify programming.

    A new location is necessary to avoid overwriting the original device configuration, which may cause incorrect sensor/parameter labeling and create parsing issues on the web. A NexSens support specialist will walk you through this process, rename the old device, and ensure the new device is reading correctly.
  • Page 94 If the user only adds sensors/parameters, these will be added to the end of the configuration, and the user can update without a NexSens support specialist. In that instance, the user should do the following: 1. Reconnect the antenna to the data logger.

  • Page 95: At What Voltage Should Batteries Be Replaced

    Factors such as the number and types of connected sensors, logging interval, transmission interval etc. influence the required power supply. A general rule of thumb is to consider replacing the X2-SDL’s (16) D-Cell batteries when the voltage falls below 9.0V. At a minimum, however, replace X2-SDL batteries when the reported system voltage falls to 8V (1V per cell).
