Long Deployments
RBRquartz3 Q
Tide and wave logger
The RBRquartz³ Q integrates the Paroscientific Digiquartz® pressure sensor for best-in-class accuracy and low drift performance. Intended for long-term autonomous or realtime observations of water level, tides and waves, the RBRquartz³ Q can resolve small changes over long deployments.
- Long deployments
- High accuracy
- Quartz stability
- 240M readings
- Up to 16Hz sampling
- USB-C download
- Twist activation
- Wi-Fi option
Features & Configurations
The RBRquartz³ Q can record instantaneous pressure measurements, average pressure samples to remove wave action, and burst-sample pressure at up to 16Hz for wave height and period calculations. Wave measurements are made by burst sampling, with programmable sample rate, number of samples, and burst interval. High accuracy marine temperature data are recorded with each measurement. Wave, tide, and temperature measurements are standard with every RBRquartz³ Q.
The RBRquartz³ Q pressure recorder is ideal for applications such as long-term wave, tide, and sea level measurements, high-accuracy depth sensing in ROVs and AUVs, and critical engineering projects such as offshore platform leveling, dam and reservoir level sensing, and underwater pipe surveying. Online applications are enabled via RS-232 or RS-485 communications. Data transmission to a surface buoy can be performed reliably using the RBR inductive modem system.
