RBRquartz BPR

RBRquartz³ Bottom Pressure Recorders

RBR bottom pressure recorders offer the best in class accuracy and resolution for wave, tide and tsunami montioring. Suitable for long term deployments in the deep sea with capability for interfacing data in real time to ocean observatories.

Product Description

BPR Loggers

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. The RBRquartz³ BPR is intended for long-term autonomous or real-time observations of water level, tides, and tsunamis in deep water. The high resolution (10ppb) and accuracy (0.01% FS) quartz pressure sensor is able to detect minuscule changes in water level from the bottom of the ocean. Continuous measurements allow the RBRquartz³ BPR to be used for tsunami detection and early-warning systems when connected to a cabled real-time network. Flexible measurement schedules and configurable integration times permit applications for tide and sea level measurements when powered on internal batteries.

Shallow Water Options

The RBRquartz³ Q tide and wave recorder is a shallow variant of the RBRquartz series. The RBRquartz³ Q packs the same high specification Paroscientific Digiquartz® pressure sensor and internal marine temperature sensor into a 750m depth rated plastic housing. The quartz Q is an ideal choice for highly accurate wave and tide measurements in shallow water environments.
