Automatic Triaxial
Brand : Controls – Italia
Standard : BS 1377:7 | ASTM D2850 | ASTM D4767 | BS 1377:8 | BS 1377:6 | ASTM D7181
Main Features :
– Automatic execution of up to 6 independent triaxial tests from start to finish with only one PC;
– type of tests: total and effective stress, stress path, K0, permeability and unsaturated soils;
-high-speed PC closed loop control for continuous monitoring and istantaneous reaction of systems components;
– user-friendly software for remote control and test procedure;
– automation components can be also applied to any existing manual system for automatic mode upgrade;
– space efficiency design;
– no need of air compressor (with exception of unsaturated soils tests);
– ideal solution for high demands laboratories which requires high productivity and reliability;
– AUTOTRIAX 2 features:
Expandability: the modular design conception allows easy expansion of the system without test interruption.
Reliability: external factors and inconsistencies between different operators are eliminated; test procedures are standardized in a test regime.
Autotriax 2 can perform different kind of triaxial tests as:
– total and effective stress tests as UU (unconsolidated undrained), CU (Consolidated undrained) and CD (consolidated drained) in isotropic conditions according to ASTM and BS Standards;
– stress path tests following MIT and Cambridge methods;
– K0 anisotropic volume controlled tests;
– Permeability tests in triaxial cells according to BS 1377: 6;
– Unsaturated soil triaxial test with control of matric suction using the axis traslation method.
In typical automatic triaxial configuration includes:
1. Load frame and triaxial cell with accessories: the proper model can be selected from our range (see Triaxial load frame TRITECH and Triaxial cells for advanced applications or Double wall triaxial cells for unsaturated tests required for unsaturated test ) or, as alternative, existing machines can be used ;
2. Data acquisition and control unit connected to a PC (using a LAN network);
3. Hydromatic 2 pressure/volume controllers with open/close automatic valves: the pressure controllers can reach up to 3500 kPa and have a volume capacity of 250 cc;
4. Triaxial test automatic control and processing software.
The Autotriax 2 configurations can be extended and expanded in subsequent steps in order to control furter tests adding proper components. These operations can be easly made on site just configuring the user-friendly software, as a plug-and-play system.
The closed-loop feedback control system monitors the components status countinously in order to react to any change in the parameter pre-setted at each test stage.
More than 30 system configurations are available. For detailed information, including the complete list of equipment and related accessories see Automatic triaxial test systems: Automatic triaxial system configurations.
