Standard triaxial system with analogue measurement

Mecánica de Suelos - Static triaxial systems : Standard triaxial system with analogue measurement

Standard triaxial System with analogue measurement is the ideal basic solution for performing standard triaxial tests such as effective and total stress laboratories that don’t require digital measurement.  All the data acquisition and test management are made in manual mode
Power supply is only required for air compressor and for triaxial load frame during failure stage. 

A typical Standard triaxial system with analogue measurements includes:

Load frame:

- TRITECH 50 kN or 100 kN: TRITECH original high-performance load frames for triaxial tests, ideal solution for advanced and research laboratories that perform high quality tests at high productivity levels.

Triaxial cell with accessories: standard triaxial cell with dedicated accessories for performing and preparing samples from 35 mm to 100 mm diameter.

Analogue measuring system: in a standard triaxial system

Pressure system: Air/water interface with air compressor and air filter, generally used for effective stress (two pressure lines are required for cell and back pressure)
Oil/water interface is also available, suggested when only total stress test (UU) is required.

Template for data processing and reporting: generally used in system with automatic data acquisition, but thanks to the high flexibility they can be used with manual input of data also in standard triaxial systems with analogue measurement.
