Third principalstress, max load to be 60MPa, accuracy is 0.5%FS；
Cylindrical specimen: Dia. : 50-150mm,100-300mm；cube specimen: 100mm³；
Accuracy of static controlling ≤ 0.5%FS， Accuracy of three-way dynamic disturbance control ≤ 1%FS；
Temp range：-10~150℃；
Pressure chamber w/ high temperature and high pressure through lead：60 core，temp for-20~200 ℃ ，pressure:200MPa；
It can perform static triaxial test of complex stress path；
True triaxial test of three-way dynamic disturbance can be carried out. The maximum frequency of unidirectional excitation of axial principal stress is 20Hz.The maximum separately excited frequency in the other two directions is 8Hz;The max frequency of three-way simultaneous compound excitation is 5Hz .The phase can be adjusted in one cycle. The controller is a double kernal CPU with 1.33GHz frequency, 2GB RAM and 4GB ROM ; High-speed interfaces within USB2.0; 1Gbit communication rate of one Ethernet adapt to the RJ45 network interface. Total four panel are reach to 10KHz at same time and the frequency also to be 10KHz. The controller can directly connect to U disk, HD, SDHC , and the data will storing into PC controller . Double insurance which avoids the data lossing while computer crashing, so as to integrity and security of data；
Characteristic：
High degree of automation and efficiency, Sealling,injecting, and ejecting automatically of pressure chamber, w/o manual manipulation
It will finish 6-8pcs testing per one staff by each day
The rate of closed-loop of all channel is 10KHz, Loading include stress, strain, displacement and arbitrary switching control, it also available for subsection control of stress, strain, displacement, axial direction during testing
Multiple protection: over load, overvoltage, overheating and misoperation. Pressure chamber adopts the newest double-deck intertwine structure, which enhanced the safety and the explode will never happen
Built-in pressure chamber of load sensor would eliminate the affect of friction. Besides, improving the measurement accuracy of axial load
The controller can connect to USB, HDDD and SDHC directly, Data can be stored in the controller external device directly, PC as well. Data double insurance to prevent computer crashing and data losing.The The controller can independent working and run stably for a long time.There is any influence while the computer crashed
