Electromechanical load frame (AOS) for consolidation testing
Product Code: GDSAOS
Categories:
The GDS Automatic Consolidation System (GDSAOS) is a modern alternative to the traditional suspended weight system.
GDSAOS is an independent stepper motor-driven unit that can be controlled manually using the Smart Keypad or from a PC via a USB interface.
No compressed air or manually placed weights are required.
When used with GDSLAB control and data acquisition software, GDSAOS can be used for a complete range of tests beyond those that can be performed by suspended weight consolidometers.
Standards
AASHTO T-216, ASTM D-2166, ASTM D-2435, ASTM D-2435M, ASTM D-3877, ASTM D4546-14, BS1377/5, CEN ISO/TS 17892-5, CEN ISO/TS 17892-7, EN ISO/TS 17892/5, JGS0411, JGS0412
Features and Advantages
| Automatic transition between test increments for all soil types without requiring user-entered parameters during test setup: | Test results on overconsolidated clay have shown a 42% reduction in test duration. |
| Direct replacement for suspended weight oedometer systems: | GDSAOS is a standalone unit (no compressed air required). Its small footprint significantly reduces the required bench space and additionally eliminates the need for loading weights. |
| Automatic data logging (and optional reporting): | Automation saves time on recording results and controlling the test. |
| Incremental loading stages: | When using GDSLAB, GDSAOS can be pre-programmed with multiple incremental loading stages that automatically proceed to the next stage via a pre-programmed consolidation end, increasing sample throughput. |
| Accurate results across the load range: | From 1N to 10kN, GDSAOS electro-mechanical pressure-controlled systems provide accurate results compared to pneumatic consolidation systems, which are typically inaccurate at low loads. |
