DSA-12 Differential Strain Curve Analysis Measurement Device
The GCTS DSA-12 Differential Strain Curve Analysis Measurement Device is designed to test cubical rock specimens under hydrostatic conditions in order to determine the in-situ stress state. The results acquired from using the GCTS DSA-12 allow the user to characterize different parameters (porosity, distribution, orientation of cracks).
The GCTS Differential Strain Curve Analysis Measurement Device (DSA-12) is designed for testing cubical rock specimens under hydrostatic conditions in order to determine the in-situ stress state. The results obtained using the DSA-12 allow for characterization of the distribution of crack porosity with crack closure pressure as well as the crack orientation as a function of crack closure pressure amongst other parameters.
The DSA-12 comes with twelve high precision LVDT’s vented for pressures up to 140 MPa with cables to connect to electrical feed-throughs inside the triaxial cell.
GCTS offers the hydrostatic triaxial cell (HTRX-DSA) with a 140 MPa pressure capacity. HTRX-DSA features stainless steel construction with 16 feed-through lines, 4 clusters of 4 lines, for in-vessel instrumentation, 3 fluid pressure connectors (cell, drain and bleed ports), 100 mm (4 inch) inside diameter. HTRX-DSA accommodates DSA-12 device with the 12 LVDT’s and 50 mm x 50 mm x 50 mm cubical rock samples.
