Temperature Controlled Hollow Cylinder Apparatus (THM)
The Hollow Cylinder Apparatus enables the operator to apply rotational displacement and torque to a hollow cylindrical or soil specimen of soil. This modular testing apparatus is suitable for static and dynamic test and can simulate the complex loading conditions at a point in a soil Specimen. The device can also be used as a cyclic triaxial testing device by changing the upper and lower pedestals into solid ones. It is capable of testing axial strain levels lower than 0.00001 %.
APS (Wille Geotechnik®) is manufacturing and providing variety range of electromechanical or servo hydraulic Hollow Cylinder Apparatus in variety range of load/torque and frequencies for many years which enable us to cover all needs of the users for testing small and large sample sizes for different applications.This machine gives a lot of flexibilities to the users to run advanced complex tests with highest accuracy and precision and add different upgrading module to system to configure the required testing applications.
Different temperature ranges for frozen tests or high temperature tests or both are also available.
- For frozen soil tests down to -20 °C
- High temperature tests up to +200°C
