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 CDAS2, Pressurematic allows for the confinement of pressure and back pressure up to 3500 kPa. The unparalleled performance of the CDAS2 allows the 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.
