Pressurematic is the new solution for geotechnical laboratories
demanding automatic pressure and volume control. By using a
servo stepper motor directly controlled by the TestLab software and
CDAS, Pressurematic allows to build confining pressure and back
pressure up to 3500 kPa. The unparalleled performance of the
CDAS allows to regulate the pressure under a closed loop control
regulated to 0.1 kPa.
The operation is continuously monitored by the TestLab software,
thus catering to all levels of operator experience.
Standard effective stress tests require 2 Pressurematic units: one
for cell pressure and the other for back pressure which can be also
used to measure the change in volume of the specimen to 0.0003
cc. The latter is provided with a solenoid valve directly installed
on the triaxial cell and used to open and close the pressure line
whenever it is needed.
