Soft Inclusion Stress Cells-Model 4360
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.
Standard Range: ±35 MPa
Resolution: 35 KPa
Temperature Range: −20°C to +80°C
Borehole Diameter: NX, PQ, HQ, 152 mm
