SEAGUARD® Recording Current Meter The SeaGuard RCM series is a completely new generation of current meters based on the SeaGuard data logger 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. Optional parameters are available through a new range of smart sensors that include temperature, pressure, conductivity, oxygen, wave and tide. The new SeaGuard RCM series come in 300m, 2000m and 6000m depth ranges. Advantages: • Large storage capacity on SD card • Broadband ZPulse multi-frequency technology reduces power consumption and improves quality • Down to 2 second recording interval • Low current drain • Smart sensor topology based on a reliable semihigh speed CANbus interface (AiCaP) • Up to 4 Analog sensor input (0-5V) • Windows CE based datalogger with TFT based color touch panel for local configuration • SeaGuard Studio visualization software • For use in sea and fresh water • Real-Time XML Output (optiona The new SeaGuard RCM series replaces the industry standard RCM 9 and RCM 11 series. It has been completely redesigned from bottom up and employs modern technology in the datalogger section and in the different sensor solutions. for most applications.The SeaGuard also has a built-in power calculator which gives an etsimated deployment lenght bases on selected interval, battery type and current drain information, obtained from each smart sensor. The SeaGuard architecture is based on a general data logger unit and a set of autonomous smart sensors. The data logger and the smart sensors are interfaced by means of a reliable CANbus interface(AiCaP), using XML for plug and play capabilities. During power-up, each of the sensors that are connected to the bus will report their capabilities and specifications to the data logger. The data logger then assembles the information and provides the user with the possibility to configure the instrument based on the present nodes. The solution provides for great flexibility in both use and design of the different elements within the system. The SeaGuard RCM comes standard with the ZPulse multi-frequency Doppler current sensor. The new current sensor comprises acoustic pulses of several frequency components to lower the statistical variance in the Doppler shift estimate. The advantage of this is reduced statistical error with fewer pings, providing increased sampling speed and lower power consumption. The autonomous sensor topology also gives the sensor designer flexibility and opportunities where each sensor type may be optimized with regard to its operation, each sensor may now provide several parameters without increasing the total system load. Data storage takes place on a Secure Digital (SD) card. The current capacity for this card type is up to 2GBytes, is more than adequate The new Doppler Current Sensor also incorporates a robust fully electronic compass and a tilt sensor. The SeaGuard RCM may also be delivered with new smart sensor solutions for Temperature, Pressure, Conductivity and Oxygen. All sensors have increased resolution compared with the older models. The temperature sensor also has decreased settling time to utilize the increased sampling speed provided by the SeaGuard platform. There is also an analog Turbidity Sensor available for direct connection on the top end plate.

Illustrations and Descriptions The ZPulse Doppler Current Sensor (DCS) is the standard sensor on the SeaGuard RCM. The sensor outputs Absolute Current Speed and Direction, Speed in east and north direction, Ping count, and extensive readout of quality control parameters such as Single-ping Standard deviation, Heading, Tilt in X- and Y-direction, and Signal Strength. The SeaGuard RCM utilizes the wellknown Doppler Shift principle as basis for its measurements. Four transducers transmit short pulses (pings) of acoustic energy along narrow beams (600, 300, 150, or 50 pings in each recording...
