Model 4360 Soft Inclusion Stress Cells (VW) | Discontinued

Model 4360-1-1 Soft Inclusion Stress Cell (hydraulically actuated. This product has been discontinued).
  • Model 4360-1-1 Soft Inclusion Stress Cell (hydraulically actuated. This product has been discontinued).

The Model 4360 Vibrating Wire Soft Inclusion Stress Cells (SISC) are larger versions of the Model 4300 Borehole Stressmeters. The SISC is pre-loaded by wedging it into a large size diamond drill hole using an integral screw mechanism or hydraulic piston and can be set to measure both tensile and/or compression stress changes. It has been used successfully in 152 mm diameter overcoring holes (drilled to measure in situ stresses) to measure Aggregate/Alkali Reactions (AAR) in concrete dams.

The Model 4360 has been discontinued. Please see other Stressmeters for a suitable replacement.
