- Possible connection with Data acquisition and processing system
This test determines the rate and magnitude of consolidation of a soil specimen restrained laterally and subjected to a number of successive increments of vertical loads.
The 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 the Data acquisition unit - See optional accessories for more information.
Consolidation cells, dial gauge/displacement transducer, weight sets and bench are not included and have to be ordered separately. See accessories.
Technical Specifications
- Max loading (using 11:1 beam ratio): 1848 kg, corresponding to 9.061 MPa (92.40 kgf/cm2) on 20 cm2 specimen (50.47 mm dia.)
- Overall dimensions: 500x200x750 mm (height less hanger xwidth x length)
- Weight approx.: 21 kg

Automatic Shear Testing Machine
The microprocessor control system, therefore, allows the machine to work as an automatic stand-alone unit: the test measurements (force and displacements) a re directly displayed and stored in memory according to pre-set recording modes. The PC is only temporary required to download the test data via the RS 232 port once the test is completed. The data can be processed by the Direct and residual shear Geo-Analysis templates. See accessories.
Shearmatic - Automatic Shear Testing Machine
This microprocessor based advanced model, is a stand-alone machine, driven by a high-resolution stepper motor with epicyclical reduction gear with reduced backlash. Incorporate a pneumatic closed loop system for the automatic application of the axial pressure by a high performance pressure regulator, with the main advantage of eliminating the manual loading of the dead weights. Excellent and high resistance techno-polymeric material has been adopted for the carriage of the shear box. It offers excellent resistance to corrosion, wear and tear and is resistant to all chemicals found in a soil specimen. The carriage is lightweight and easy to clean.
Laboratory Vane Apparatus
The laboratory vane apparatus is based on an original concept of the Transport and Road Research Laboratory of the United Kingdom. It offers versatility with a variety of vane sizes available. Typically it comes with the standard 12.7 mm square vane along with a set of four calibrated springs. Testing can be conducted either directly on the sample or within the sampling tube. For the latter, the NG-WF1738 Attachment for 38 and 100 mm diameter sampling tubes is recommended for optimal performance.
