RBRquartz³ BPR

The RBRquartz³ BPR (Bottom Pressure Recorder) uses an integrated Paroscientific Digiquartz® pressure sensor for the best-in-class initial accuracy, resolution, and low drift performance. This instrument is intended for tsunami detection, tide monitoring, long-term water level studies, and high-resolution depth sensing in ROVs and AUVs.

High resolution and accuracy of the quartz pressure sensor enable water level observations in deepwater. Continuous measurements allow the RBRquartz³ BPR to be used for tsunami detection and early-warning systems when connected to a cabled realtime network. Flexible measurement schedules and configurable integration times permit applications for tide and sea level measurements when powered on internal batteries. A high-accuracy marine temperature sensor records temperature data with each pressure measurement.

Realtime data applications are enabled via USB, RS-232, RS-485, or Ethernet communication. Data transmission to a surface buoy can be performed inexpensively and reliably using the RBR MLM inductive modem system. Innovative canister design allows for easy access to the battery compartment and fast data download via USB-C. Datasets can be read directly in Matlab, or exported to Excel, OceanDataView®, or text files.

Key features of the RBRquartz³ BPR are:

  • High accuracy

  • Quartz stability

  • Long deployments
