HMA - Model 3000 -Hydraulic Borehole Stress Cell
The Model 3000 Hydraulic Borehole Stress Cell is a soft inclusion type cell consisting of an inflatable flat jack with or without platens. The cell is placed in a 50mm diameter borehole and then pressurised. Stress change is monitored with either a Bourdon tube gauge or any suitable diaphragm type pressure transducer (see Model 1200 for details) or both.
