Permeability and Triaxial Shear
How To Order
Step 1. Select Permeability and/or Triaxial Cells
ASTM* D 2850, D 4767, D 5084 AASHTO* T 296, T 297
* See Standards Buyer's Guide at www.DGSI.info/3000 .
The DGSI Triaxial and Permeability Cells are designed to accommodate samples with diameters from 1.4 to 12 in (35 mm to 305 mm). They feature no-volume-change valves and removable base pedestals to accommodate various sample sizes and the piston housing features linear bearings for reduced friction. Two top and two bottom drainage lines are provided with through-base-sealing to avoid air traps.
S-480 is the standard model for testing test specimens up to 4-in diameter and about 6-in in length. It is equipped with both 1.4 and 2.8-in cap and pedestal set made of series 303 stainless steel (SS). In addition, the valves are stainless steel and tubing is Teflon. These are for customers that might be testing material where the permeant is corrosive or they need to test both 1.4 and 2.8-in specimens. Finally, the customer may decide on the standard models because the SS valves will not tarnish with age. Note:
If the permeant is corrosive the customer will require the S-470 permeant interface device to protect the control panels.
Designed to provide outstanding service and performance. The cells have hard-coated, black anodized aluminum bases and cell tops, while remaining parts are made of stainless steel, brass or acrylic.
S-511 Triaxial and Permeability Cell
S-480 Permeability Cell shown with a Pore-Pressure
Transducer (sold separately).
Measuring changes of the test specimen length during testing:
• S-500 series triaxial cell equipped with bracket for mounting dial indicator (E-814) or displacement sensor LDT E-311.
• S-480 series triaxial cells do not have that provision. To measure height change during testing, use S-500 series triaxial cells.
!
Know the following before making your selection:
• Will you be performing triaxial tests, permeability tests, or both?
•
•
What size samples will you be testing?
How many simultaneous tests will you be performing?
When using corrosive permeants, always select permeability cells with stainless steel valves. In addition, the Permeant Interface Device,
(S-470) is recommended to prevent the permeants from entering the panels. See page 26 for details.
Note: All cells include cap and pedestal set (sizes and type below), one pair of porous stones, two plastic discs, Nylon tubing and O-rings.

Step 2. Choose your panel(s)
Note: Select the type and quantity of each panel based on the number of cells needed for simultaneous testing. One S-500 panel can support up to two S-502 extension panels. The S-502 extension panels cannot operate independently from the S-500. All DGSI panels are built with quality gauges, valves, and fittings.
Contact DGSI to request a quote to meet your needs.
The DGSI master panel (S-500) and extension panel (S-502) control the pressure and permeant flow to and from the triaxial or permeability cell. The S-500 contains the main operation panel which includes air and vacuum gauges to monitor the main supply, de-airing tank fill, vacuum, and pressure controls, an auxiliary vacuum port, and a pressure transducer and digital readout with a selector valve for monitoring pressure to each burette.
Each cell being tested requires three individual burette assembly used to monitor the cell pressure, sample bottom pedestal, and sample top cap. The S-500 can supply one cell and the S-502 can supply up to two cells. The S-502 is connected to the S-500 using tee fittings and tubing from the back of the S-500 panel. Pressure readings from the S-502 are displayed on the S-500 readout via momentary switches.
Each burette assembly is constructed with acrylic tube and top and bottom blocks with stand-off fittings for easy removal to clean or service as needed. A standard glass pipette (25 ml with 0.1 ml markings) is supplied inside each burette assembly. Optional pipettes of 10ml, 5ml, or 1ml are available upon request. All pipette markings are factory calibrated.

Step 3. Select Utilities for Panel
Selection of proper permeability/triaxial support equipment is essential for ensuring proper panel operation and accurate results.
DGSI panel setups require a suitable deairing tank, vacuum pump, compressed air and accessories for proper operation.
Clean, dry air and vacuum sources are strongly recommended to maintain consistent performance. Consider adding a vacuum pump water trap kit (G-39620), air dryer w/oil extractor (G-420), and a filter regulator (G-41020) to maximize panel efficiency.
Nold Water Deaerator
The self-contained Nold deairing system deairs six liters of water to less than 0.5 ppb dissolved oxygen in 4 min. It operates by mechanical agitation with the application of a vacuum. The agitation / vacuum system is significantly more efficient than conventional methods using heat-boiling methods. The system uses a 0.02 hp electric motor an is great for labs that have to perform tests quickly. Dimensions: 7.5 in x 7.5 in x 20 in
(19 x 19 x 51 cm).

Step 5. For Triaxial, Choose Transducers and Readout Options
Skempton’s Value or “B” Value is an important value used in permeability and triaxial testing. DGSI's sensors and readouts are used to monitor pore water pressure within the sample being tested. The end result is used to calculate and determine sample saturation values (“B” Value).
Each DGSI transducer requires a subordinate readout device to display the output signal.
!
The EZ-Daq is recommended when...
• Three or more sensors / readouts are needed.
• When multiple tests (sensors) are being run simultaneously.
(WinSAS software does not support simultaneous testing.)

Soil Lathe
(Sample Trimmer)
Specifically designed for trimming samples to precise diameters using a fine wire trimming knife. Adjustable in ranges from 1 to 4-in in diameter by simply changing the top platens.
Model S-57628 includes a 1.4-in and a 2.8-in platen with a 3.0 inch pedestal. Models
S-57629 and S-57630 require selection of top platens from the table below. We can also handle special requests for sizes not shown.
Permeant Interface Device
(Bladder Accumulator)
Used in permeability or triaxial testing when a corrosive fluid is the permeant.
It is installed between the permeability cell and the panel. Consists of a flexible bladder to prevent the permeant from entering the panel or escaping into the atmosphere. It also eliminates the possibility of compressed air dissolving into the permeant. All liquid contacting parts are made of 316 stainless steel, Teflon ® or Viton ® . The Permeant Interface
Device is supplied with both Buna-N and
Viton ® Membranes.
The cylinder has an inside diameter of 2 in (51 mm). 185 ml.

Replacement Pressure Regulators
Bleed-Type Pressure Regulators are recommended for maximum sensitivity and stability against upstream supply pressure changes. All regulators are designed to accept supply pressures up to 250 psi. The supply pressure should always be at least
20 psi above the maximum regulated pressure and the regulator capacity should match the gauge or pressure transducer capacity.
These regulators have a sensitivity of less than 1/4 in. of water.
Differential pressure regulators are used to maintain a preset pressure difference between two pressures even if the pressure is raised or lowered.
