The electromechanical pressure generator EPD2000 can be integrated into a wide range of test systems in which pressures have to be precisely regulated, volumes have to flow over a certain time or pressures and volumes have to be measured.
The main areas of application are the generation of cell pressure and pore water pressure in triaxial tests, the indirect measurement of the change in sample volume in triaxial systems, and pressure generation and volume measurement in permeability systems.

The pressure generator works on the plunger principle and displaces a volume of 1000 ml without refilling the device. The volume measurement is performed by the measurement of the piston movement and correction by the stress-strain curve of the completely hydraulic system. The stress-strain curve will be automatically recorded and saved by the EPD2000 themselves. The pressure measurement can be done by the built-in transducer or with an external pressure transducer e.g. directly on the sample (triaxial cell).

The reference value for the pressure or flow rate is given by touch screen or by the connected PC with the software GeoDESC.
