RBRquartz³ Q
The RBRquartz³ Q uses the proven Digiquartz® pressure sensor to achieve stable long-term measurements for water level and wave observations. 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.
