Triaxial / Permeability Control Panel

• User-friendly
• Quick disconnects for easy system cleanup
• Easily expands for multi-cell test

The Triaxial/Permeability Control Panel delivers accurate and easy triaxial and permeability testing. Easy for the technician to perform functions at various test stages; for example; de-aired water preparation, sample preparation and cell assembly, cell filling, confining pressure application, sample saturation by back pressure increments, isotropic consolidation, and hydraulic gradient setup for permeability testing or open drainage for triaxial testing.

All controls are laid out in a logical order. The upper half of the panel contains controls for air pressures while the lower half contains the water controls. Precision regulators set and control pressures. Whitey ball valves are used for positive shut-off. Two 50 cc burettes, graduated by .1cc, for flow measurement and two 4cc pipettes graduated to .008cc, are also included. These are located inside two storage chambers which have an additional 400 cc capacity each.

The Cell’s water interface utilizes a 20 cc burette. The operator is able to fill and drain the panel and cell conveniently from the front panel. A bias control feature allows the user to set the effective cell pressure and also increase both the cell and sample backpressure using only one regulator. This is useful when saturating the specimen and causes no change in effective stress. It also minimizes air consumption during saturation as only two of the three regulators are utilized at this time.

Connectors for easy access to air, water, vacuum and drain are located on the rear of the panel. All connections and tubing for the cell are conveniently located on the front of the panel.
