Resonant Column Device
The Wille Geotechnik resonant column is a high-quality piece of equipment designed to determine geotechnical properties of materials (e.g. soils) under low strain ranges for solid- or hollow-cylindrical samples. Resonant column devices are made with high-frequency electromagnetic torsional drives. These are used to vibrate the top of a soil specimen at frequencies of up to 2000 Hz in the first-mode resonance while the bottom is fixed or second mode while top and bottom are free.
The components used in the Wille Geotechnik RC are of the highest quality possible. The triaxial cell is designed for pressures of up to 1000 kPa. The volumes and pressures of the pore fluid are precisely monitored and controlled with an automatic pressure controller or pressure control panel. The system includes a data acquisition unit to collect different measuring values, such as force, travel, pressure, frequency, temperature and more. Transducers and sensors that provide analogous signals can be connected.
