The closed-loop servo control system which is composed of electric controller, servo valve, loading sensor, displacement sensor, extensometer and computer, can automatically & accurately control test process, automatically measure test parameters such as testing force, displacement, deformation, torque, and angle etc .
The testing machine can achieve sinuidal, triangle-wave, square-wave, sawtooth-wave, negtive-sawtooth wave, pulse-wave and other waveforms, can perform tensile, compression, bending, low-cycle & high-cycle fatigue tests. An environmental chamber can be configured to perform environmental simulation tests at different temperatures.
The testing machine operation is flexible & convenient. Cross-head lifting, locking and sample clamping are all operated by button. Thanks to advanced hydraulic servo loading technology, high-precision dynamic loading sensor and high-resolution magnetostrictive displacement sensor, the machine measure testing force and displacement automatically. Fully digital measurement & control system enables PID control for force, deformation and displacement, and achieve smoothly switch between each others. The testing software run under WINDOWS XP / Win7 with powerful data processing ability, can automatically save, display and print test conditions and results.
