This series of Dynamic Triaxial test systems gives the possibility to perform large load and frequencies on the required specimen size in combination of static or cyclic cell pressure. The Wide column spacing enables to accommodate large cells even with environmental chambers and furnace.The Triaxial system is able to generate and apply different types of loading waveform can be given to the sample e.g. Sinusoidal, Square, Triangular,Rectangle, Ramp signal and user defined waveform.
This machine gives a lot of flexibilities to the users to run dynamic tests with high dynamic loads on each required sample size. The high accuracy and different upgrading module smake possibility to configure the test system which meets all your testing applications. When you have any testing applications, we can assist you in configuring a system to meet your test requirements. All of our testing solutions are manufactured to the high quality and standards. Oursystem comes with a powerful dynamic controller up to 10KHz and this makes a unique feature for our machines in dynamic testing field. A unique and flexible software along with components bring you different possibilities to use the device and run your test in a better way.
These high quality stress path triaxial testing systems are a modular solution and are consisting basically of a rigid 2 column-load frame, a cyclic actuator, a multi-channel high speed control system with 24 bit resolution for dynamic axis load and actuators for cell-pressure, back-pressure and optional pore air pressure and strain measurement components. The powerful multifunctional GEOsys Software supports all the test procedures with a well access to all testing sessions.

Servohydraulic Dynamic Load Frame
This series of high-quality servo hydraulic closed loop controlled triaxial load frames are suitable forgenerating high accuracy static and dynamic loads for compression or extension in uniaxial or triaxialtests.
It comes with an efficient testing area and iscapable to run the tests from small strains to largestrains in static and dynamic modes. Depends onthe model of the load frame, it can accept varietyof specimen sizes and even with environmentalchambers and furnace. The actuator is located at upper crosshead andthe power supply unit is located in special acousticenclosure. The cylinder and all its accessorieshave been enclosed for protection. After adjustingcross beam, it can be fastened manually on thechrome-plated shafts. Thus, the cross beam canbe moved to and fastened at all required heights.The dynamic servo hydraulic load frame hasdifferent models which could be selected per asrequired technical test specification of the usere.g:Table top model,Floor type model,in type model (independent dynamic -static actuators)
Hydraulic Power Pack
Our series of hydraulic power-packs supplysmooth hydraulic fluid to actuators, hydraulicpressure intensifiers, and servo hydraulic testingmachines to meet their testing system demands.A key feature of our hydraulic power packs is thatthey offer demand-dependent flow-rate control,delivering at a constant pressure of 210, 280 bar.
They can locate beside or in greater distance fromload frame. An oil-to-water heat exchanger or aircooling exchanger controls fluid temperature. Atemperature switch turns the hydraulic powerpack off when the temperature of the fluidexceeds a pre-set value – lights on a front panelare used to indicate temperature levels
Soil Triaxial Cell
This series of Stress path Triaxial cells designed for static and dynamic soil testing to testcylindrical soil specimens with diameters from 38mm up to 150 mm, a length/diameter ratio of at least 2under triaxial conditions. The cells cover variety range of tests which is required in the geotechnical labs.
High Pressure Triaxial Cell
This is an advanced high-pressure/high temperature triaxial cell designed to test cylindrical specimens with diameters of up to 102mm, a length/diameter ratio of at least 2 under triaxial high pressure/temperature conditions up to 50MPa.
Static Cell And Back Pressure System
The cell and back pressure can be generated and controlled automatically by different configurations depends on the testing applications, laboratory utilities and technical requirements in a variety range of pressure and for different applications With both below configuration which automatic and are controlled via PC, Tests such as Saturation, stress/strain path, permeability, K0 and other tests can be easily performed with accuracy and precision.
A) Air Pressure Controller (APC)
The standard configuration of this series includes of one-off Air pressure controller (APC) to generate air pressures (e.g. confining and pore pressure), two-off Air/Water Bladder which acts as an interface to exchange pneumatic pressure into hydraulic pressure and one -off automatic water volume measuring device to measure volume changes.
This system is fully automatic system and is controlled via PC and dedicated software.
Working pressure: 2 MPa Pressure outlet:3 for inner cell, outer cell and backpressure
B) Volume Pressure Controller (VPC)
This method included of two Volume Pressure controllers for applying back pressure and Cell pressure. These are syringe pulse-less pumps which generate and regulate pressure and provide flow control in a variety range for different testing requirements.
The control of the units is simply done via Touch-panel for stand-alone use or via PC and dedicated software. This making them very convenient and easy to operate.
Digital Controller
Digital High-Speed High Resolution Expandable Real Time Control and data acquisition System 10KHz control and data acquisition and 24 bit resolution. The Dynamic controller is suitable for screw driven instruments(electromechanical) , hydraulic instruments with a valve driven with ±10 Volt and variety of sensors e.g. load cells, LVDTs, strain gauges, extensometers, thermocouples and etc.
The multi-functionality of the controller allows a modular design of the measurement and control parameters (sensors) via intelligent sensor plug, which store the calibration parameters, thus depending on the application can be used flexibly.
