Chapter 1 : Introduction
1.1 Introduction
The SODIMAT - Model 9073 permits the
measurement of sodium in industrial
ultrapure waters.
The measurement is based on a direct
potentiometric technique using a highly
sensitive sodium glass electrode. The
difference of potential between the glass
electrode and the reference electrode is
directly proportional to the sodium
concentration as shown by the Nernst law:
1.2 Applications
Modern high-pressure power plants require
feedwater of very high purity. Safety in that
sector is of great importance and the
sodium measurement plays a specific role
compared to pH, conductivity and silica
trace.
Actually, sodium cations and anions are
always linked. Most cations have a
corrosive influence in water and vapor
cooling circuits.
Because of this chemical link between
sodium ions and anions, sodium
measurement presents particularly
important risks of corrosion and other
effects.
The presence of chlorides, for example,
involves corrosion under power and when it
exceeds allowable concentration limits.

Chapter 2 : Description of the analyser
2.1 Principle of operation
The SODIMAT 9073 uses a sodium-interferences by other ions, especially ions
sensitive glass electrode to measureH+. Low-level sodium measurements,
sodium in a sample which has beentherefore, require that the H+ of the sample
previously conditionned to a pH > 10.water be adjusted to a level several orders
Sample conditionning is necessary because of magnitude below the level of sodium. For
sodium glass electrodes are not perfectlythis reason, the SODIMAT 9073
specific sensors, but are subject to

2.4 Electronics
To reach the interior of the instrument (for
electrical wirings, EPROM removal, power
supply control), remove the 4 front panel
screws, fixed to the microprocessor's board.
The electronics of the SODIMAT hold 3
printed circuits, 2 of them are located
behind the front panel :
#The display board with a liquid crystal
display, status LEDs, control keys and the
microprocessor.
#The analogue board including the
measurement module (sensors input) and
the analogue/numeric conversion unit.
#The third one is located behind the
protective cover in the main enclosure. It
includes the power module, the outputs, the
relays and the RS232 interface. In addition
it includes the terminal board connections
from 1 to 29.
