RBRquartz³ BPR: Bottom Pressure Recorder

The RBRquartz³ BPR uses an integrated Paroscientific Digiquartz® pressure sensor for the best-in-class initial accuracy, resolution, and low drift performance. The RBRquartz³ BPR is intended for long-term autonomous or real-time observations of water level, tides, and tsunamis in deepwater.

  • Long deployments
  • High accuracy
  • 10ppb resolution
  • 240M readings
  • Up to 16Hz sampling
  • USB-C download
  • Twist activation
Download Datasheet

The RBRquartz³ BPR is ideal for tsunami detection and early-warning systems, providing continuous measurements while connected to a cabled realtime network. Flexible measurement schedules and configurable integration times enable water level and tide observations in deep water.

The Paroscientific Digiquartz® pressure sensor supports instantaneous pressure measurements, average pressure measurements over specified sampling duration, and burst-sample pressure measurements at up to 16Hz. A high-accuracy marine thermistor 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.
