Model No. LO7010/100/EM/1
This high-quality and stiff multifunctional testing machine. It is suitable for a variety of testing, such as static and dynamic, axial and torsional, uniaxial and triaxial shear tests. These can also be done in two variations, a hydraulic axial/torsional system, and a electromechanical axial/torsional system. This hollow cylinder system is modularly constructed. It can be configured with a variety of sample adapters, triaxial cells, pressure plates and other customized attachments. Different software packages and further accessories to suit specific testing needs are also available. This system is capable of performing rotational displacement and torque tests on a hollow cylindrical soil sample. There are two types of hollow cylinder testing machines available, with an above or below load piston, depending on the loading system in use i.e. a servo-motor or servo-hydraulic actuator. It is also possible to control the magnitude and direction of the three principal stresses. The main field of application is the determination of soil behaviour in underground traffic or earth-quakes, unbound material testing (liquefaction strength tests) with high resolutions and the synchronized measurement of channels.
These control systems are designed for static & dynamic applications for high-quality test performances of up to 100 Hz. High-quality controllers and an A/D resolution of up to 20 bits for closed-loop control are used to achieve this.
This series of machines uses the latest digital technology to ensure accurate and repeatable results from test to test.
Increasingly complex demands are made on material testing systems. The digital control systems we offer include operation, visualisation, digital control, evaluation and documentation.
This high performance digital controller enables the execution of either static or fatigue tests. The controller is either available as a single or multi-channel system with phase shift control in real-time modus. Modular digital controllers are supplied for closed-loop control in load, displacement, deformation or external modes (seismic recordings) as well as data acquisition. This high-resolution controller is specially designed for static and dynamic testing up to 100 Hz in connection with testing machines.
