The LoadTrac III is a compact, lower cost load frame with flexibility to run fully automated compression/extension testing for popular geotechnical tests that must have accurate control of the rate of displacement during loading.
LoadTrac III can run in stand-alone mode (ideal for teaching) or can be connected to a PC for full automation from test start to finish without intervention by the user. The compact design allows many units to be placed on a lab table to save space and increase productivity.
The load frame houses a high speed, precision micro stepper motor that moves the load platen and thereby applies a vertical load to the soil specimen. An embedded control board with a dedicated CPU uses readings from the force and displacement transducers to determine what signals should be sent to the stepper motor. The control board is capable of applying a new vertical load increment within one second and accurately maintaining that load while monitoring the displacement.
Addition of FlowTrac flow pumps expands the capabilities of the LoadTrac III to perform Constant Rate Consolidation (CRC/CRS), Triaxial & Stress Path, or Fully Automated Permeability.
