Item Description
E-124 Pore Pressure Transducer, 0-150 psi range x 0.1 readability
E-8000E EZ-Daq 8-Channel Data Acquisition System, English units
E-8000M EZ-Daq 8-Channel Data Acquisition System, SI units
Optional Equipment
E-405 Smart Digital Indicator
Skempton’s Value or “B” Value is an important value used in
permeability and triaxial testing. DGSI's sensors and readouts
are used to monitor pore water pressure within the sample being
tested. The end result is used to calculate and determine sample
saturation values (“B” Value).
Each DGSI transducer requires a subordinate readout device to
display the output signal.
Smart Digital Indicator, E-405 and Pore Pressure Transducer, E-124.
Transducers sold separately.
EZ-Daq, (E-8000E or E-8000M), shown with an S-type load cell, two (2) linear displacement transducers and a pressure transducer.
Transducers sold separately.

Transducer
The EZ-Daq is recommended when...
!
• Three or more sensors / readouts are needed.
• When multiple tests (sensors) are being run simultaneously.
(WinSAS software does not support simultaneous testing.)
E-344, Adaptor for Linear Displacement Transducer (LDT) may be needed
with permeability cell depending on your set up.
