Data Logger
With the help of data loggers, oceanographic and geophysical parameters can be monitored cost-effectively and in real time or recorded for later analysis. Nautilus Marine Service GmbH offers a wide range of data loggers and sensors from the Canadian companyRBR Ltd. Based in Ottawa, the name RBR stands for the development and manufacture of highly precise sensors and data loggers for applications in oceanography, limnology, geophysics, as well as groundwater and polar research.
Two main factors summarize RBR’s Generation³ instruments: USB-C as the standardized connection and AA batteries—ranging from alkaline to lithium—used in every device.
To easily identify an RBR Generation³ instrument from an older logger, an important mechanical component is highlighted in red for better distinction.
Other important updates of the Generation³ include a further reduction in the instruments’ power consumption—for example, the RBRconcerto³ CTD is now the oceanographic CTD on the market with the lowest power consumption. The input voltage range has also been expanded to 4V to 30V.
The sampling rates have also been improved with | fast8 and | fast16. For CTDs mounted on rosettes and other specialized applications, RBR has developed a data rate of up to 32Hz: | fast32.
Sensors
RBR sensors are industry-leading in terms of accuracy, stability, and power consumption—even under the most challenging conditions.
Their industry-leading low power consumption enables long deployments at depths of up to 6,000 meters, making them the perfect choice for many oceanographic and limnological applications, such as monitoring boreholes, remotely operated underwater vehicles, current measurements, and harbor water levels.
The real-time sensors have the following features:
- High accuracy,
- Low power consumption,
- Long deployment times,
- Compact and lightweight,
- RS-232-Output,
- MCBH-6-MP-Connection,
- Depths down to 6000 m
Available sensors:
Temperature (T), pressure (D), dissolved oxygen (DO), optical dissolved oxygen (ODO), photosynthetically active radiation (PAR), radiometer (rad), fluorescence (Fl)
