Automatic transition between test increments for all soil types, with no need of user estimated parameters input during test set-up:
|
Results from tests on over consolidated clay, produced a reduction in test duration of 42%.
|
Direct replacement for a hanging weight oedometer system:
| The GDSAOS is a stand-alone unit (with no requirement for compressed air). Having a small footprint significantly reduces the bench space required coupled with the additional advantage that loading weights are not required.
|
| Automated logging of data (and optionally reporting): | Automation saves time recording results and controlling the test. |
| Incremental loading stages: | When using GDSLAB the GDSAOS can be preprogrammed to include numerous incremental loading stages which automatically move to the next stage via preprogrammed end of consolidation conditions, thus increasing sample throughput. |
| Accurate results throughout the load range: | From 1N to 10kN the GDSAOS electro-mechanical pressure controlled systems provide accurate results, compared to pneumatic consolidation systems that are typically inaccurate at low loads. |
| Utilise existing equipment: | If upgrading from a PC logged hanging weight system, it may be possible to utilise the current data logger and transducers as many data loggers, even those from other manufacturers, are compatible with the GDSLAB software. |
