The GDS permeability system allows the user to independently control the cell, back & base pressure to perform constant head & constant flow tests though an automated system.
GDSLAB software. There are two cells types available, a purpose built 100mm cell that allows for isotropic testing, or a standard triaxial cell, which can be upgraded for anisotropic testing and to run full triaxial tests.
| Key features | Benefits to the user |
|---|---|
| Easily Upgradeable: |
The system can be easily upgraded to a fully automated triaxial system. |
|
Each system can be configured to the customer’s specification and budget: |
The user can choose the pressure controllers, triaxial cell or just parts to integrate into existing equipment to build their ideal set-up. |
| Automated software control: |
The software directly controls the cell & back pressure, testing rate, in addition to managing all data acquisition. |
|
Compatible with other manufacturer’s products: |
If a user has existing components they can incorporate them with GDS equipment to create a system, saving expense. |
|
Varying pressure ranges: |
Standard pressure ranges of 1MPa - 4MPa. |
|
Range of Triaxial Cells: |
GDS have a range of different sized cells available for permeability testing. Specimen sizes range from 38mm up to 150mm in diameter. |
|
Interchangeable Pedestal & Topcap: |
This reduces the costs when changing specimen sizes that are still supported by the chosen cell. |
|
Configurable set-up: |
The system can be configured for commercial testing with several systems running from a single controlling computer, or for higher range research testing allowing for increased pressures and accuracy. |
