Consolidation Apparatus

BS 1377:5 | ASTM D2435 | ASTM D3877 | ASTM D4546 | NF P94-091 | EN 17892:5
The ACE EmS is a versatile and fully automatic Oedometer soil consolidation testing machine that comes loaded with the new environmentally friendly Electromechanical Servoactuation (EmS) technology.

Silent, compact and highly performing, the ACE EmS testing system can be run with our ingenious software that can connect up to 60 units with just one PC, enabling you to expand your laboratory gradually and seamlessly.

26-WF31E20: ACE EmS - Electromechanical Servoactuation, automatic oedometer machine.
100-220 V, 50-60 Hz, 1 ph

Important: either the software or the local user interface (see below) are mandatory for running the machine

26-WF31E20/SW: PC software for remote control and data acquisition up to 60 units connectable to a single PC.

26-WF31E20/T: Optional local user interface with 6” touch screen high resolution color display allowing full control of a single ACE EmS including full test execution.

Main features:
  • Versatile fully automatic Oedometer soil consolidation testing machine featuring incremental loading, swelling, CRS (constant rate of strain), CHG (controlled hydraulic gradient) and unconfined test.
  • Environmentally friendly and quiet — the ACE EmS benefits from the new Electromechanical Servoactuation (EmS) technology requiring no dead weights or large & noisy air compressors, thus drastically reducing noise levels.
  • Modular and expandable, gradually connect up to 60 units via LAN port using the same PC software allowing you to build your laboratory without interruption — resulting in excellent return on investments.
  • Small footprint featuring a benchtop shorter than 50 cm.
  • Highly performant with load capacity of up to 20 kN, equivalent to 10,000 kPa on 50.47mm Oedometer consolidation cell.
  • Optimized PID closed-loop control delivering fast, smooth and accurate loading and precise load holding through the multiple test steps.
  • Optional local user interface with 6” touch screen high resolution color display allowing full control of a single unit, without a PC, including full test execution. USB pen drive included for unlimited storage, TXT format data output.

The ACE EmS can complete the whole test in fully automatic mode by selecting the load (stress), offering a practical and accurate way to obtain reliable results without any need for manual intervention, reducing the risk of human error.

Front loading oedometer consists of a rigid aluminium alloy frame to avoid any distortion under load. The lever arm assembly is supported in precision self- aligning bearings and has three hanger positions for 9:1, 10:1 and 11:1 ratio. The oedometers fit with linear potentiometric transducers, can be connected to Data acquisition unit.
