Pressure logger

摘要

RBR, Canada, reports the commercial release of the new RBRquartz3 Q|plus pressure logger "to meet the demands for high-accuracy, long-term measurements of sea level, tidal and wave dynamics by coastal oceanographers worldwide"."At the heart of the RBRquartz3 Q|plus is an integrated Paroscientific Digiquartz pressure sensor for best-in-class initial accuracy, resolution and low-drift performance," said the company. Intended for long-term autonomous or real-time observations, the new system can resolve water level changes as small as 100ppb at 16Hz sampling rate - for example, at 50 metres depth that would be a resolution of ±0.005mm.The RBRquartz3 Q|plus also comes standard with a ±0.002°C high-accuracy temperature sensor and may be configured with an optional three-axis tilt sensor. In combination with RBR's Ruskin software, the end-user has the availability of flexible measurement schedules, burst sampling and configurable integration times to allow for a broad range of applications in coastal dynamics.Greg Johnson, president of RBR, said: "The RBRquartz3 Q|plus addresses the demands of scientists and engineers who require long-term quartz pressure sensor measurements in a package where ease-of-use is prioritised. We are happy to bring this instrument to the market and fill the gap that is present."
