TIDE SENSOR 4647/4647R is a compact fully integrated sensor for measuring the tidal conditions. The 4647 sensor is designed to be mounted on the AADI SEAGUARD® or connected to SMARTGUARD using AiCaP CANbus or in other measurement systems using the RS-232 interface. The 4647R sensor is designed for use with long cables by means of RS-422 full duplex interface. Advantages: • Smart Sensor technology - plug and play • Sensor Calibration coefficients are stored in the sensor • Low maintenance needs • Low current drain • Output formats 4647: AiCaP CANbus, RS232 • Output formats 4647R: RS-422 • Selectable interval from 1 sec. to 255 min. • Tidal averaging period: 10 sec. to 8 min. • 2Hz and 4 Hz sampling frequency • Output parameters: Pressure, Tide pressure, Tide Level, Temperature. • Real-time XML output • Measurement range: 400, 700, or 3100 kPa • Maximum operating depth: 300m 4647/4647R is based on a silicon piezoresistive pressure sensor. The pressure measurements are sampled and temperature compensated by an advanced Digital Signal Processor. The sensor application areas are in fixed installations, either deployed in a seabed installation in shallow waters, or mounted onto a fixed structure in the upper water column. The tide measurement is an average of the hydrostatic pressure measured over a time period of 10 seconds to 8 minutes (Integration time configurable by the user). The update interval is between 1 second and 255 minutes. The Tide sensor output parameters are Tide pressure, Tide level, Pressure and Temperature. Tide levels are preliminary, internally calculated estimates, based on fixed, user selectable values of atmospheric pressure and water salinity. Compensation for actual atmospheric pressure and salinity can be postprocessed if such data is available. Tide pressure is an average of hydrostatic pressure over the integration time. data are stored inside the sensor, the parameters are by default presented directly in engineering units without any external calculation. The sensor also provides raw data of the pressure and the temperature measurements. Tide Sensor 4647 is a compact yet intelligent sensor designed to be used with AADI SMARTGUARD or SEAGUARD® as well as in other measuring systems. The SMARTGUARD/SEAGUARD® and the smart sensors are interfaced by means of a reliable CANbus interface using an XML based protocol (AiCaP). The Smart sensors can be mounted directly on the top-end plate of the AADI SEAGUARD® and are automatically detected and recognized. The output format of Tide Sensor 4647 are AiCaP CANbus and RS-232, while the output format of the 4647R version is RS-422. The sensor version must be specified when ordered as the two versions are not interchangeable. The R-version cannot be used in SEAGUARD® applications. Since all calibration and temperature compensation The Tide sensor can be used as stand-alone sensor with AADI Real-Time Collector for real-time data.
