1.3.1 WET SECTION UNIT
The 9033X Sodium system is capable of monitoring sodium concentrations in sample
feed. Three solenoid valves are used to select between analyzing the sample,
calibration solution 1 (CAL1), calibration solution 2 (CAL2) and grab sample.
In normal mode, the feed water flows through the flow switch, into the heat exchanger,
through the solenoid valves and into the flowcell where it comes into contact with the
sodium and reference electrodes. The electrodes transmit a voltage proportional to the
sodium content in the feed water. This output is then measured by the electrical system
and converted into a ppb/ppm measurement. An internal thermistor (housed in
flowcell) is used to monitor the sample temperature for temperature compensation. If
the sample temperature exceeds 131°F, sample automatically gets diverted to drain and
the system displays “HOT”.

1.3.2 PRE-AMPLIFIER
The 9033X Sodium analyzer requires a pre-amplifier unit which amplifies and converts
the voltage output from the electrodes into proportionate current. Thermistor output is
also fed to transmitter unit via pre-amp section. The pre-amplifier houses the wiring
connection terminals from electrodes. The DIN style cables from the pre-amplifier allow
for quick and easy change-out of electrodes.
1.3.3 TRANSMITTER UNIT
The transmitter unit interprets electrode response and temperature output from the
pre-amp and displays the corresponding sodium concentration (in ppb/ppm) and
temperature. The transmitter unit controls all the operations of the analyzer system.
The display is a touch screen HMI.

2.1.1 LOCATION AND LAYOUT
Mount the analyzer in a clean, vibration-free area avoiding direct radiant heat, sunlight
and drafts. Avoid areas containing chlorinating equipment. The 9033X Sodium analyzer
default design has the two main sections (transmitter and wet section) combined as a
single unit. If necessary the sensor unit can be mounted separately as long as it is no
more than 330 feet (100meters) from the transmitter unit.
2.1.2 TRANSMITTER UNIT
The transmitter unit controls the operations of the analyzer. Power supply, CPU card,
Analog card and input power terminal junction are housed in the transmitter enclosure.
Transmitter unit is a NEMA 4X rated enclosure with cable glands for wiring. Size and
layout of transmitter is shown below.
Figure 4. Dimensions of the transmitter unit. (All dimensions in inches)
2.2 SAMPLE REQUIREMENTS
The maximum sample pressures and temperatures specified in the SPECIFICATION
section should not be exceeded. The sample should be introduced to the system at a
temperature and pressure suitable for measurement. If necessary, customer may
choose to use sample cooling and pressure reducing equipment. It is highly
recommended that a flow meter is installed to the sample inlet stream to ensure that
the sample flow rate is within the specified range. When pressure reducing equipment
is being used, a pressure relief valve should be installed between the sample point and
sample inlet to ensure maximum safety.

2.4.3 AUTOMATIC KCL REFILL SYSTEM (OPTIONAL)
Figure 7. Layout of the Automatic KCl Refill System.
Directions for installing and using the KCl refill system:
1. Feed inner (smaller diameter) tubing through outer (larger diameter) tubing.
2. Feed inner tubing through the side-arm of the reference electrode and connect
the outer tubing over the side-arm.
3. Clip nozzle of KCl bottle, making sure the hole is large enough for inner tubing to
pass through and that KCl solution can flow freely around it.
4. Insert inner tubing through nozzle of bottle and connect outer tubing over the
nozzle of bottle. Make sure the inner tubing reaches the top of the bottle while
the other end remains inside the reference electrode.
5. Install KCl bottle into the bottle clamp and finger-tighten wing nut to hold the
bottle in place.
6. Poke a small hole in the top of the bottle so KCl flows freely and vacuum does
not form.
7. Rinse off any spilled KCl with DI water before installing probe in the flowcell.
(KCl will interfere with sample reading if it gets in the flowcell.)

2.4.4 PROBE INSTALLATION PROCEDURES
1. Remove the protectors from the tip of each electrode
2. Connect electrodes to wires from Pre Amplifier. Be sure to match the correct
wires to the correct probe. Wires are marked “M” for measuring and “R” for
Reference.
3. Use fingers to rotate the probe positioning clamp counterclockwise to loosen.
Carefully insert the electrode through the clamp and into the flowcell.
Electrodes may have to be inserted at an angle.
4. For reference electrode - insert the electrode so that the tip of the electrode is
5mm into the sample. Correct placement within the flow cell is important. Refer
to figure below.
5. For measuring electrode –insert the electrode so that the tip is just off the
bottom of the flowcell. Refer to figure below.

9033X Sodium Analyzer
Connecting the power supply earth (ground) ensures the safety of
assembly personnel, reduction of the effects of Radio Frequency
Interference (RFI), and ensures operation of the power supply
interference filter.
Before connecting the analyzer to the main power supply check that
there is correct voltage at the mains.
Although this instrument has internal fuse protection, the operator must
use a suitably rated external protection device such as a fuse or
miniature circuit breaker (MCB).
Switch OFF the power supply and high voltage power-operated control
circuits before making any connections. This equipment operates on
alternating current (AC) electricity. Always take suitable safety
precautions to avoid the possibility of an electric shock.
