The Constant Rate of Strain cell (CRS) of Controls Group

CRS - Constant rate of Strain Cell to be used with external load cell CRS - Constant rate of Strain Cell to be used with external load cell.

The Constant Rate of Strain cell (CRS) is used to measure the magnitude and rate‐of‐consolidation of saturated cohesive soils using continuous controlled‐strain axial compression.

The specimen is restrained laterally and drained axially to one surface. The axial force and base excess pressure are measured during the deformation process. Controlled strain compression is typically referred to constant rate‐of‐strain (CRS) testing. The test is performed using Constant Rate of Strain cell and other equipment including Triaxial frame, Pressure system, Data acquisition and processing system and other accessories. It can be used in a standard system with manual control (automatic or manual acquisition) or in an automatic control and data acquisition using a dedicated activation code.

MAIN FEATURES

  • Continuous monitoring of test parameters (axial load, pore pressure, axial compression) and detailed plotting of the consolidation curve
  • Max working pressure 3500 kPa
  • Relatively short time to perform consolidation test
  • Particularly suitable for cohesive saturated soils
  • Using with standard system with manual control or using dedicated activation code with automatic control and data acquisition.

Three different models are available:

  • Constant rate of Strain (CRS) suitable for external load cell
  • Constant rate of Strain (CRS) suitable for submersible load cell
  • Adapter for triaxial cell model 28-WF4070
