Conductivity Sensor 4319
is a compact fully integrated sensor for
measuring the electrical conductivity
of seawater. It is designed to be used
with SMARTGUARD or SEAGUARD®
datalogger using AiCaP CANbus or as
stand-alone sensor using RS-232
Advantages:
•t Smart Sensor for easy integration with
SEAGUARD® and SMARTGUARD
•t Direct readout of engineering data
•t Internal pressure never exceeds 1 bar
therefore electronics and sensors are
unaffected by sea depth
•t Rugged and Robust with low maintenance needs
•t Output format AiCaP CANbus, RS-232.
•t 3 depth ranges available maximum
6000 meter

Conductivity is a key parameter for in-situ
determination of several fundamental
physical properties of seawater.

Utilization of miniature components have
made it possible to integrate all the required
electronics.

For seawater, the ability to conduct electrical
current is mostly dependent on temperature
and the amount of inorganic dissolved solids.
This means that, together with temperature
and depth information, a good estimate of
the salinity may be determined.

The Conductivity Sensor outputs data in
AiCaP CANbus and RS-232. Output
parameters are Conductivity and Temperature
in AiCaP and Conductivity, Temperature,
Salinity, Density and Sound speed. Data can
be presented in Engineering unit or raw data.

Salinity is defined as the concentration of
dissolved solids. Other important properties
of seawater are again dependent on the
salinity. Among these are the density and
the speed of sound.

The SEAGUARD® datalogger and the smart
sensors are interfaced by means of a reliable
CANbus interface (AiCaP), using XML for
plug and play capabilities.

The Conductivity Sensor 4319 is based on
an inductive principle. This provides for
stable measurement with­ ut electrodes that
o
are easily fouled and may wear out in the
field.

The smart sensors can be mounted directly
on the top end plate of the AADI SEAGUARD®,
in a String System node or connected to
the SMARTGUARD and are automatically
detected and recogniced.
