Learn about Wykeham - Farrance's Automatic Computerized Oedometer and discover its unique capabilities! Soil's rate and magnitude of consolidation can be easily and more importantly reliably evaluated with ACE!

Oedometer consolidation testing is used for the determination of the rate and magnitude of consolidation of a soil specimen restrained laterally, while subjected to a number of successive increments of vertical load. Wykeham - Farrance's ACE (Automatic Computerized Oedometer) consists of a small and compact load frame housing two coaxial pneumatic cylinders: the smaller one for low loads and the other for higher loads, with automatic switching from one to the other when needed. Two analogue channels control the displacement transducer, as well as the load cell with closed-loop feedback, which is used for the monitoring of the application of the required pressure using a high precision servo-pneumatic actuator. Test parameters are pre-programmed and saved in the ACE software by the operator, including the test end, which can be programmed on a time basis or increment. The software can control up to 60 units from a single PC ACE, giving the operator the choice of controlling single or multiple units.

Each channel can record up to 8 points of calibration. Test results are recorded and displayed in real time and calculations are performed automatically. Additionally, test data can be processed using the proper Geo-Analysis Templates conforming to BS or ASTM Standards.
