- current-driven motor that applies torsional load to the sample
- a series of transducers with signal conditioning
- cell and back pressure electro-pneumatic control system
- data logger.
- RC: damping ratio from half power bandwidth, free vibration data and white noise
TSS: damping ratio from hysteresis loops
Robust design and long lasting: Sturdy construction minimizes losses and helps to deliver a consistent frequency response. The stainless steel base cell with acrylic transparent cylinder won’t rust or corrode, prolonging your equipment’s life.
User-friendly Graphic User Interface (GUI). The high quality laptop PC supplied with pre-installed intuitive Windows-based software allows you to perform various stages: saturation, isotropic consolidation, resonant frequency and torsional shear. The 7” color touchscreen with high resolution display makes cell, back and pore pressure easy to monitor.
Efficient and time-saving: The software uses the “Chirp Method” to continuously change the frequency applied to the sample. This method experiences no jumps when changing from one frequency to another improving strain measurement resolution and shortening testing time.
Easy saturation: additional upper drainage is included ensuring proper sample saturation.
High resolution and accuracy: Proximity transducers are mounted on the automated positioning system which automatically places them in the best measuring position after saturation and consolidation, eliminating the need for any manual adjustments during the test.
