The NexSens X2-CBMC is an all-in-one environmental data logger specifically designed for offshore use with a NexSens CB-Series data buoy. It automatically recognizes sensors and sends data to the web via cellular or Iridium satellite telemetry. The X2-CBMC includes five sensor ports that are compatible with most environmental sensor protocols including SDI-12, RS-232 and RS-485. All connections are made using MCIL/MCBH wet-mate connectors, and the built-in sensor library automatically facilitates setup and configuration. Sensor data is recorded on common or independent schedules.
The X2-CBMC is powered from the CB-Series buoy’s solar rechargeable battery reserve. Advanced power management combined with ultra-low sleep and run currents extend battery life and reduce the need for larger buoy and solar charging systems. The X2-CBMC monitors itself while collecting environmental data. Internal temperature, humidity, voltages and currents are constantly recorded. Failure alerts can be sent automatically to a predefined list of contacts.
The X2-CBMC integrates the sensor ports, solar panel connector, pressure relief valve, and wireless antenna all on the data well lid for quick installation on CB-Series data buoys. Integrated cellular or Iridium satellite telemetry modules offer real-time remote communications via the WQData LIVE web datacenter. There, data is presented on a fully-featured and easy-to-use dashboard. Other features include automated reports, alarms, push notifications and much more.
