BS 1377:5 | ASTM D2435 | ASTM D3877 | ASTM D4546 | NF P94-091 | EN 17892:5

ACE EmS - Electromechanical Servoactuation, automatic oedometer machine (26-WF31E20) complete with consolidation cell (26-WF0320)
Calibration and verification facilities via software. Txt files are automatically generated for calibration reports. Each system is factory calibrated.
Real time data of load and displament using touchscreen dispaly (26-WF31E20/T)
Consolidation cells 26-WF0320-WF0335
Detail for load cell, displacement transducer and consolidation cell
Test files can be easily uploaded on the Geo-Analysis templates for data processing; the above screenshot shows the calculation of t50 through the graphical setting of the primary and secondary consolidation fitting lines.

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.
