Features
● Adopting Japanese AC servo system, the computerized torsion testing unit is loaded through the active clamping head driven by the AC servo motor and cycloidal pinwheel reducer.
● High-precision symmetrical torque transducer to measure test torque and high-precision photoelectric encoder to measure torsion angle.
● Dual control modes: manual control and computerized.
● Windows-based software is used to evaluate torsion property of materials. The functions include automatic test data processing, display of test curves in real time, storage and print out etc.
● Torsion curves, loading speed, peak value etc can be displayed in real time.
● The computerized torsion testing machine confirms to standards of ASTM A938, ISO 7800, GB/T239, GB10128 and others equivalent.
