TRIAXIAL ACOUSTIC P-S1-S2 SYSTEM FOR Ø38.1mm (Ø1.5”) SAMPLES COMPLETE WITH STRAINING FRAME
Features:
Axial load applying platens incorporating P-S1-S2 acoustic transducers
Standard 69MPa (10,000PSI / 690BAR) Confining Pressure
Standard 67MPa (9,700PSI / 670BAR) Pore pressure. Pore pressure is applied through two flow ports to flow distribution grooves on the axial platen face plates
OPTIONAL: 2 channel strain gauged cantilever in the cell annulus for radial deformation measurements
OPTIONAL: 2 LVDTs externally mounted on the axial platens for axial deflection measurement
OPTIONAL: Signal conditioning / data capture electronics and Software
This apparatus can be used in conjunction with the clients Load / Straining Frame; alternatively a Straining Frame can be supplied by ErgoTech (OPTIONAL)
OPTIONAL: Internal Heater capable of 200°C (requires the Software and Electronics option)
OPTIONAL: Resistivity measurement option
OPTIONAL: Confinement and Pore fluid pumping systems
NOTE: If all options are required, please see the “Floor Standing Acoustic System specification
This unique design allows rapid loading / unloading of samples without the necessity to drain the confinement fluid and remove the core sleeve.
The core sleeve is only be removed when adapting the cell for other sample diameters (Ø1.5” setup shown here) or to replace a damaged / worn core sleeve.
The platen adaptors are interchangeable, as a result this one cell can be configured to accept the specified sample diameters listed on the previous page.
This Triaxial system allows independent axial and confinement pressures. Note: Axial pressure must always be maintained approx 2MPa above Confinement Pressure to avoid damaging the Double Lip Core Sleeve.
Features:
Axial load applying platens incorporating P-S1-S2 acoustic transducers
Maximum axial load of 100kN with standard Ø38.1mm (Ø1.5”) axial platens relating to 87.7MPa contact stress on a Ø38.1mm (Ø1.5”) sample.
Accommodates Ø38.1mm (Ø1.5”) samples
The system includes the ErgoTech Variable Pulse Width Transducer Pulser Unit (PT100-1000) with a variable pulse width range of 100-1000ns
P-S1-S2 wave selection is controlled manually using the Transducer Pulser Unit
The wavefroms output to a Digital Storage Oscilloscope with RS232 output to clients PC
OPTIONAL: Fully configured PC or Laptop available
