The SediGraph III 5120 uses operator input for these parameters to perform an analysis and
produce reports:
• Sample density
• Liquid viscosity and density
• Starting and ending diameter
• Type of analysis: High speed, Standard or High Resolution
• Choice of stopping at a certain mass percentage
• Report options
See section Chapter 3, The Analysis Sequence, for more detailed information.
The SediGraph III 5120 system consists of the cabinetry, Fluid Control module, Analysis
module, X-ray generation, X-ray detection, data collection, and a computer for data reduction
and reporting.

Cabinetry SediGraph III 5120 Service
Cabinetry
The cabinetry used for the SediGraph III 5120 provides the mounting structure for the fluid
module, Analysis module, power supplies, card cage, air flow control, flood control, cabinet
interlocks and all interconnecting cables for these assemblies. These assemblies can be further
broken down into the following components.
Top Panel
The top panel is removable. There are two magnetic interlocks located under the panel on the
side rail.These interlocks require the use of an interlock defeat tool (PN 512/25850/00) to
allow generation of X-rays when the top panel is off. The Anal ysis module and th e control and
display panel (key-switch, X-ray status lamps and Pump kill) are accessible through the top
panel.
Rear Panel
2-2 Mar 2010
SediGraph III 5120 Service Cabinetry
The rear panel is a removable panel which allows access to the 24VDC and the Quad
switching power supplies used in the instrument. There are cut-outs in this panel to allow air
flow out of the instrument.
Cooling air is drawn into the instrument from two fan assemblies on the bottom, passed over
the internal components, and vented to the outside through the rear panel. The X-ray tube
cooling fan has an aluminum deflector which forces air across the tube for extra cooling
capability. There are sensors to alert the operator if a fan has lost 30% of its power.
Fluid Module Cover
A cover houses the fluid module and the mixing chamber, and helps with noise abatement.

SediGraph III 5120 Service Fluid module
Fluid module
The purpose of the fluid module (PN 512/ 34006/00) is to control th e flow of fl uid into an d out
of the instrument for rinsing and cleaning, and to load and circulate sample material. It is
located in the lower part of the instrument behind the fluid module cover and consists of the
following components.
Mixing Chamber
The mixing chamber is located under the fluid module cover, on the left side of the instrument.
The chamber allows circulation of fluid through the pumps, valves and up to the sample cell
assembly. The chamber also houses an RTD and a heater cartridge for temperature control.
Mar 2010 2-5
Fluid module SediGraph III 5120 Service
There are four chambers available.
• 511/25870/00 (standard chamber) is an aluminum large bore chamber.
• 511/25870/02 is a stainless steel large bore chamber used when high pH levels or caustic
materials are present.
• 511/25875/00 is an aluminum small bore chamber.
• 511/25875/02 is a stainless steel small bore chamber used when high pH levels or
caustic materials are present.
A cable assembly (PN 510/60817/00) is embedded in the wall of each type of mixing chamber .
This cable has two heater cartridges and an RTD. The cable is the only serviceable part of the
mixing chamber.
There are future plans to offer an optional module which will act like the older predecessor to
the 5100. A module with one pump is planned in the future (like a 5000 manually-operated
instrument). The 5120 will see this due to two bits being used in the cable to decode which
type of chamber is present.
Magnetic Stirrer Assembly
A magnetic stirrer assembly (PN 512/34005/00) is located directly beneath the mixing
chamber. It includes a stepper motor with a magnet attached to the output shaft. This assembly
stirs the fluid to keep particles from settling during an analysis.
There is an interconnect PCB (PN 512/17709/011) located directly behind the stirrer assembly
that allows connection of the mixer chamber, magnetic stirrer, all valves, and pump motors at
the back side of the magnetic stirrer mechanism. These signals pass through this PCB with no
manipulation.

during a rinse operation, or to help rid the cell of bubbles during a fill operation, or whenever
the instrument determines there are bubbles in the sample.
Fluid pumps
There are two pumps used in the 5120, both are located at the front of the fluid module. Both
pumps have EZ Load pump heads (PN 512/62800/00) and pump motors (PN 511/25889/00).
Both pump head assemblies are attached to mounts which have vibration dampening
grommets (to help cut down on vibration and noise).
Cell pump
This pump (PN 512/62800/00) controls flow (speed and direction) through the cell assembly.
This pump is also used when 100% (full scale) runs are made before a sample is run. Loading,
emptying and rinsing of the cell assembly all are accomplished using the cell pump. The flow
rates of the cell pump are below: The tolerance of all of these speeds is +
10%.

The I/O & Control PCB allows connection of the 5120 to a computer, provides interfacing
connectors for the instrument, and monitors critical functions of the 5120. The PCB features
the following:
• An RS232 connector and a 9-pin connector on the edge of the PCB, addressed as Com2.
• X-ray & Photomultiplier tube interface - the PCB has four independent 1,000,000 count
A/D channels used to monitor X-ray current, X-ray voltage, Photomultiplier voltage
and the temperature. The PCB has a 2MHz clock to run the V/F converters on the PCB,
monitors the Key-switch position, reports this position to software, monitors the
interlock circuitry (Door, key-switch, top panel and the X-ray ON LED condition) This
board latches into X-Ray OFF mode whenever the top panel is removed or when there
is an over current condition of the X-ray tube. Both of these conditions require the
operator to turn the key-switch Off and back On to generate X-rays.
• Period Averager interface - performs the period averaging function for both the Kilocounts and the temperature conversions needed for proper operation.
• Fan monitor - there is a fan monitor bit for each fan to determine when the fan’s speed
has fallen below a set threshold. When a fan’s speed gets below approximately 30% of
the rated speed, an error message is generated to alert the operator to the problem.

cell limit switches. The stepper and heater control PCB features:
• 2X stepper motor control w/L297, L298N and L6210 chipset for speed, direction and
motor drivers. This board has two stepper motor channels to drive and control the cell
stepper and the mixer stepper motors. The cell stepper operates from 0 to 500RPM,
while the stirrer motor operates from 0 to 1000RPM. The cell stepper also has a
direction bit for Up/Down operation.
• 2X Heater control and drivers 4A @ 24VDC. Heater drivers are controlled by two
independent hardware control circuits. These read the RTD outputs to provide a control
loop. The temperature for each circuit is compared to the provided set-point. If the
temperature is out of range, an error signal is generated and the PWM output for each
heater driver is adjusted. This signal is a 24VDC PWM signal @ approximately 200Hz.
• 2X RTD temperature channels w/ADC for software reading. Two interfaces are
provided for the 2-wire 1000Ω RTDs used in this system. The temperature
measurement range is 0 to 60°C. The signals are buffered and amplified then fed to a V

Interlock Circuitry SediGraph III 5120 Service
Interlock Circuitry
The interlock circuitry in the 5120 is very similar in operation to the 5100.
• Top panel switches - there are two top panel m a gnetic interlock switches which have
been moved to the mid section of the right hand side panel of the 5120 (due to cabinet
construction). Both of these switches must be on to generate X-rays. There is an
interlock defeat tool similar to the 5100 top panel interlock defeat tool for use in
servicing the 5120.
• There are also two magnetic switches on the rear panel, which have to be on to generate
X-rays.
• A magnet (located on the Analysis module door) and reed door switch (located on the
side panel of the Analysis module) form a series circuit that requires the door to be
completely closed before X-rays are generated.
• There are two magnets located at the rear of the fluid module that form an X-ray
interlock. For X-ray generation the fluid module must be installed in the instrument.
• The X-ray On/Standby lamps (PN 003/39046/00) form a series circuit and must be
complete to generate X-rays. The X-ray On lamp must be operable and the key-switch
must be cycled (Stand-by then back On) whenever an over-current occurs or the top
panel has been removed. Either of these conditions will cause the Stand-by light to
come on, and will not allow the generation of X-rays until the key-switch has been
cycled. When the switch is ON, X-ray generation is allowed, when in the Stand-by
position, X-rays cannot be generated.
•
2-16 Mar 2010
SediGraph III 5120 Service Interlock Circuitry
• The X-ray key-switch (located on the front panel) controls whether X-ray generation is
allowed or not. When the switch is in the ON position X-rays can be generated, when
the key-switch is OFF X-rays cannot be generated.
• The X-ray shutter assembly is operated by a push pin that rides in a plunge cut in the
Analysis module door. One end of the plunge cut is not as deep as the other, which
allows the push pin to open or close the mechanical shutter as the door’s position is
changed. The door must be completely closed to generate X-rays. There is a spring
behind the shutter pin. If the shutter pin is lost, this spring will keep the shutter closed
and not allow X-rays to be generated.

Analysis Module
:
The Analysis module on the 5120 is basically the same Analysis module used for the 5100
with these exceptions: there is no stepper drive card on the top of the Analysis module
assembly, and an updated (electronically) X-ray control board is used.
The 5120 was engineered using the same reliable safety features used in the 5100, providing
protection against accidental exposure to high voltage or x-rays. The cabinet’s color and the
updating of the electronics are the biggest changes.
The Analysis module consists of:
• X-ray tube
• X-ray adjusters
• X-ray control PCB
• X-ray tube high voltage supply
• Collimator assembly
• Cell stepper motor
• Photo Multiplier tube
• Photo multiplier high voltage power supply
• Shutter pin
• Double clamp coupling

X-ray tube
The X-ray tube (PN 510/57603/00) used in the SediGraph 5120 is the same type as that used
on previous SediGraph models. It has the same potentials set for its use, 13,600 Volts for the
high voltage accelerant and no more than 3 mA for current is set during calibration.
The x-ray adjusting system, method, and set up are the same as previous models. The springs
(PN 004/25702/00) used in the alignment process are the same as the 5100. The system works
with two alignment adjusters, which are threaded in a manner to cause the tube to move up/
down with one of the adjusters while the other adjuster moves the cell side to side.

Interlock Circuitry SediGraph III 5120 Service
The X-ray tube (PN 510/57603/00) and its floating mounting system are the same type as used
in previous models.
The high voltage is connected to the X-ray tube by a High Voltage cable (PN 510/60838/00).
Cell movement is accomplished by sending pulses to a stepper motor which is coupled to a
drive screw, an anti-backlash device which moves the cell to the correct position for the
operation in progress.
The cell stepper motor (PN 510/60829/00) has the same characteristics as the 5100 stepper
motor - 1.8° per step delivered to the motor.
The anti-backlash nut (PN 511/25600/00) is designed to take up any misalignment of the drive
mechanism. The spring keeps a constant tension on both sides of the threads it engages, this
allows the cell assembly to start moving as soon as the first pulse is delivered.

Power Supplies and Power Entrance
There are four power supplies used in the SediGraph:
• X-ray High Voltage
• Photo Multiplier Tube high voltage
• 24VDC
• Quad Switching power supply
Two of these supplies are located in the back of the instrument, behind the rear panel. The
24VDC supply is on the right hand side of the instrument, while the quad switcher is on the
panel facing you when the rear panel is removed. The X-ray high voltage is located under the
X-ray shield, which is mounted on a heat sink on the inner cabinetry. The Photo Multiplier
Tubes supply is located on the X-ray control PCB.
Exercise extreme caution when measuring or setting the high voltage. Follow all
safety precautions as voltage in excess of 13,000 volts DC is present.
The high voltage (PN 003/40062/00) supply is used to operate the X-ray tube. This power
supply is located under the top panel on the left side (looking from the front) under the X-ray
shield. It provides the accelerating voltage for the X-ray tube and has sense lines feeding back
to the X-ray control board, which are used to control the supply. The maximum output voltage
is 15,000VDC. The voltage is set for an output of 13,600VDC.

SediGraph III 5120 Service 0% Concentration Determination
3. ANALYSIS SEQUENCE
The SediGraph III 5120 analyzes particle sizes using the sedimentation method. In this
method, particle sizes are determined by knowing the gravity induced falling rates of particles
in liquid with known density, temperature and viscosity properties.
Before an analysis, the operator uses the SediGraph software to enter the sample density and
starting/ending diameters for a particular analysis. The operator also enters the density and viscosity of the sedimentation liquid. This information can be entered in either of two ways. The
operator can enter the density and viscosity at the current analysis temperature, or the operator
can create a liquid properties table for the density and viscosity at a high, an intermediate, and
a low temperature. When a liquid properties table is used, the analysis program calculates the
density and viscosity of the sedimentation liquid at the current cell temperature by interpolating between the previously entered values.
0% Concentration Determination
Prior to the first run, a baseline value needs to
be established. Pure, clean sedimentation liquid
is used for this purpose. An analysis is started,
the cell full of the sedimentation fluid is
scanned and the maximum number of X-ray
kilo-counts is detected and recorded at 220 data
collection points. During this process, the SediGraph III 5120 passes a finely collimated X-ray
beam through the transparent windows of the
analysis cell to the photomultiplier detector as
the cell moves vertically between them. At 220
data collection points, the X-ray intensity is
recorded and a baseline value is calculated. The
baseline value is for 0% concentration because
the cell contains only the sedimentation liquid.
These baseline values remain valid as long as there are no changes in the sedimentation liquid,
the shape of the cell, or the X-ray intensity.
Mar 2010 3-1
Beamsplit Determination SediGraph III 5120
Beamsplit Determination
At the beginning of any automatic run, the
SediGraph III 5120 determines the exact
position of the top of the cell relative to the
X-ray beam to establish a known starting
point for the cell movement. The SediGraph
establishes a known position of the cell by
moving it to the point where the top edge of
the cell splits the X-ray beam in half. This
beamsplit data is stored in the SediGraph
software for use in the analysis. A beamsplit
is performed by the SediGraph for each
analysis.
Immediately before an analysis, the operator disperses the sample in the sedimentation fluid.
This dispersed sample and fluid mixture is added to the SediGraph mixing chamber where it is
stirred to maintain dispersion and heated to the analysis temperature. At the appropriate time,
the fluid is pumped into the analysis cell. The SediGraph maintains circulation through the cell
to prevent sedimentation as a second scan determines the maximum (or full scale) concentration of the sample to fluid mixture.
Full Scale Determination
value is calculated. The full-scale value is used for 100% sample concentration because the
cell contains suspended particles, representing the highest particle concentration for the analysis. These particles are not allowed to settle because the cell pump is running during the
operation. For the top 2 mm of the cell, full scale values are extrapolated from the lower portion of the cell. This practice prevents any small variation in concentration of large particles at
the top of the cell from affecting the accuracy of the analysis.
Shown at the left is a sample cell full of
sedimentation liquid and particles. The
particles absorb some of the X-ray
energy as it travels from the X-ray tube
through the windows (and sample slurry)
to the transparent window of the PhotoMultiplier tube. The actual change in
absorbance with time is what the SediGraph uses in determining the particle
size. To speed up the time required for a
test, the SediGraph will move the cell
assembly down looking at finer and finer
particles.
At the 220 data collection points, the Xray intensity is recorded and a full-scale
3-2 Mar 2010
SediGraph III 5120 Service Bubble Determination
Bubble Determination
During the full-scale scan, the SediGraph III 5120
performs a bubble detection test. Because bubbles in
the sedimentation liquid could affect the accuracy of
the analysis, the pumping system attempts to remove
any detected bubbles before the analysis proceeds.
Shown for illustration is a “Small Bore” cell, most
cells are the “Large Bore” configuration and the In/
Out tubing is slightly different but, the operation is
exactly the same.
Particle Size Analysis
After the full-scale concentration data
have been collected, circulation of the
sample/fluid mixture is stopped abruptly
and sedimentation begins to occur. During sedimentation, the SediGraph III
5120 again passes the X-ray beam
through the analysis cell taking absorbance readings at the 220 data collection
points as in the 100 percent scan. An elevator moves the cell down during this
sedimentation process to accelerate the
data collection. The analysis program
compensates for the movement of the
cell when calculating the particle falling
rates.
Mar 2010 3-3
Particle Size by Sedimentation SediGraph III 5120
Particle Size by Sedimentation
As the sample particles fall, they absorb some of the X-rays
and prevent them from reaching the detector. The X-ray
intensity is recorded at each step in the cell movement. The
analysis program collects data at up to 220 sedimentation
heights based on the operator-specified starting and ending
diameters for the particle analysis. The analysis program
determines the target sedimentation heights and times based
on the run type (High speed, Standard or High Resolution)
and calculation of the particles’ terminal velocities. The rate
at which particles fall through the liquid is described by
Stokes’ Law. The largest particles fall at the fastest rate,
while the smallest particles fall at the slowest rates, until all
of the particles have settled and the liquid is clear.
Each collected intensity value is compared to the X-ray intensities at the corresponding
heights for both the baseline and full-scale concentrations for the sample. The resulting percentage is used to determine the total particle mass at each point in the cell. The analysis
program uses the percentage of particle mass and calculated particle falling rates to determine
the maximum particle size for each point in the cell (particle distribution).
The analysis data is stored in the control module and can be displayed or printed in a variety of
graphic and standard report formats. Because particles rarely exhibit a uniform shape, each
particle is reported as an Equivalent Spherical Diameter (the diameter of a sphere of the same
material with the same terminal velocity).
The SediGraph III 5120 is designed to provide analysis results which vary by no more than 2
mass percent among samples from a homogenous lot.
When the analysis is complete, the sample and fluid mixture is drained from the cell into the
mixing chamber, and then the mixing chamber is drained into a waster reservoir. If the operator has selected the rinse option, a rinsing liquid is then drawn into the analyzer and the entire
system is rinsed and drained. The rinse operation may be set to a specific number of cycles or
to continue until the previously obtained baseline concentration is achieved. Rinsing always
occurs when a MasterTech is used with the SediGraph III 5120.
