SEAGUARD® Platform The new Aanderaa SeaGuard Platform is the basic module of our new Underwater Observatory. The SeaGuard Platform is used as data logger in SeaGuard RCM, SeaGuard CTD, SeaGuard WTR and SeaGuard WLR and SeaGuard O2 Advantages: • Great Flexibility: data registration from up to 20 sensors • High resolution and low drift • Low maintenance needs • Selectable interval from 2 seconds to 2 hours • SeaGuard Studio visualization software • Smart sensor topology based on a reliable CANbus interface (AiCaP) • Real-Time XML Output on RS-422(optional) • Windows CE based datalogger with TFT colour touch panel for configuration • For use in sea and fresh water • 300m/2000m/6000m version • Available sensors: Z-Pulse Doppler current sensor, Pressure,Temperature, Oxygen optode, Pressure, Conductivity, Wave and Tide • Up to 4 Analog sensor input (0-5V), e.g. Turbidity Aanderaa Data Instruments SeaGuard Platform is a self recording instrument with storage on SD card. Storage capacity is more than adequate for any practical applications. The instrument is delivered with pressure case. The SeaGuard Platform and the Aanderaa smart sensors are interfaced by means of a reliable CANbus protocol (AiCaP), using XML for plug and play capabilities. The smart sensors can be mounted directly on the top-end plate or connected via cable to an Aanderaa SeaGuard Platform. During power-up, each of the sensors that are connected to the bus will report their capabilities and specifications to the datalogger. The datalogger then assembles the information and provides the user with the possibility to configure the instrument based on the present nodes. Since all calibration and temperature compensation data are stored inside the sensor, the parameters are by default presented directly in engineering units without any external calculation. Six sensors can be fitted onto the Top-end Plate of the Platform; four of which can be analog (0 - 5V) sensors. The SeaGuard Platform has 2 Battery Compartments for long deployment time; the AiCaP CANbus based protocol ensures low power consumption. The ouput parameters from the SeaGuard Platform are easily presented in SeaGuard Studio. The SeaGuard Platform can be configured to suite your requirements and applications. The SeaGuard Instrument can be deployed in an In-line string mooring, Fixed bottom frame mooring, Buoy deployment, Long term/short term deployment. The SeaGuard Instrument can be used with Aanderaa Real-time Collector for Real-time data.

SEAGUARD® Recording Current Meter The SeaGuard RCM series is a completely new generation of current meters based on the SeaGuard Platform and the ZPulse™ Doppler Current Sensor. Modern computer technology combined with advanced digital signal processing provides accurate and detailed measurements with almost unlimited resolution. The new current sensor comprises acoustic pulses of several frequency components to lower the statistical variance in the Doppler shift estimate. The new Doppler Current Sensor also incorporates a robust fully electronic compass and a tilt sensor. Optional...
