Multiplex Testing Machine

Multiplex Testing Machine is used to make Uniaxial, CBR, Marshall and Triaxial Tests. The device is composed of a robust and compact two column frame with adjustable upper cross beam driven by an electromechanical ram with a maximum capacity of 50 kN.
 
The testing speed can be set between 0,001 mm/min to 51mm/min. The test automatically stops when load and displacement is reached to 95% value of the set measuring range.

The Multiplex Testing Machine features a microprocessor controlled drive system with an advanced servo motor enabling the operator to easily set any test speed via the membrane keyboard. The keyboard comprises adjustment buttons such as “start”, “stop”, “down”, “up”.

The HR-E5000 Servo Controlled Multiplex Testing Machine is supplied complete with 50 kN Load Cell, 25 mm Displacement Sensor and Digital Readout and Control Unit. The other Test Accessories should be ordered separately according to the test.
5 kN Load Cell for Triaxial Tests, Compression Platens with ball seating assembly for Unaxial Tests, Penetration Piston for CBR Tests and Breaking Head for Marshall Tests should be ordered separately.

Determining the mechanical properties of soils is a very important step to design foundations, embankments and other soil structures.Building constructions, excavations, tunneling and similar applications have several effects on the subsoil structures and these effects are successfully simulated with Triaxial Tests where the stress-strain relation of undisturbed soil specimen are investigated by subjecting the soil sample to different stress levels and drainage conditions. The Triaxial Test System provides Automated Triaxial Compression Tests on cylindrical undisturbed and remolded soil samples. Unconsolidated Undrained (UU) Compression Tests can be automatically run, controlled and reported using this apparatus. 5 kN Load Cell should be ordered separately for Triaxial Tests.

UNCONSOLIDATED UNDRAINED (UU) TEST

The System is Supplied with Multiplex Testing Machine, Load cell, 5 kN capacity, Triaxial Cell for Ø38 and Ø50 mm samples or Triaxial Cell for Ø70 and Ø100 mm samples (Choose the suitable cell for the specimen size), Analog Manometer, Air and Water Constant Pressure System, Software to Perform UU Triaxial Tests and De-Airing Water Tank and Hose. Digital Manometer is optional and should be ordered separately instead of Analog Manometer.

TRIAXIAL CELLS

The cell has been designed and treated to minimize corrosion. Particular attention has been paid to the quality of finish between the piston and the head. The piston load capacity is designed to accept high axial loads which may be present during the final stages of a test.
