SD-SWCC System


SD-SWCC System

For prices: call +44 (0)118 945 3737 or Email us

The VJ Tech Stress-Dependent SWCC System (SD-SWCC) performs an advanced test which;

  • Determines the influence of the stress state on the Soil Water Characteristic Curve of a soil sample
  • Combines the determination of the SWCC at different ko stress conditions, trying to replicate the stress state occurring at deeper soil layers
  • Determines both drying and wetting SWCCs, allowing hysteresis to be studied

The system consists of;

  • A Multi-Purpose Frame with up to 3 input channels (2 x Analogue & 1 x Digital) for Vertical Force
  • A Multi-Purpose Cell with HAED & heater and temperature sensor controlled by a separate unit
  • A Pro Pneumatic Automatic Pressure Controller at the top of the Cell and a Pro Hydraulic Automatic Pressure Controller at the base to generate suction using the axis-translation technique 
  •  

SD-SWCC System

Features:

  • Air-tight cell
  • Fitted with High Air Entry Disc (5 bar)
  • Temperature sensor
  • Heater with separate variable temperature controller for controlling condensation
  • Able to determine both drying and wetting SWCCs
  • Load balance pressure compensator
  • Pro Automatic Pressure Controllers for maintaining suction
  • Motorised ACONS Pro Multi-Purpose Consolidation Frame for Vertical Load
  • Up to 5 input channels (2 x Analogue & 1 x Digital) on ACONS Pro & 1 Analogue on each APC
  • The same Frame and Cell can also be used for consolidation and CRS testing
