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:
•t Large storage capacity on SD card
•t Broadband ZPulse multi-frequency technology
reduces power consumption and improves quality
•t Down to 2 second recording interval
•t Low current drain
•t Smart sensor topology based on a reliable semihigh speed CANbus interface (AiCaP)
•t Up to 4 Analog sensor input (0-5V)
•t Windows CE based datalogger with TFT based
color touch panel for local configuration
•t SeaGuard Studio visualization software
•t For use in sea and fresh water
•t 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.
