Features :

✔ Motorized Torsion Testing System

The equipment utilizes a motor-driven worm gear mechanism that applies torsional loads smoothly and uniformly to test specimens, ensuring reliable and consistent experimental results.

✔ High-Precision Torque Measurement

A strain gauge measuring shaft accurately detects applied torque and converts it into an electrical signal for precise monitoring and analysis.

✔ Digital Angle Measurement

An incremental encoder continuously measures the angle of twist with a resolution of 0.1°, providing highly accurate deformation data throughout the experiment.

✔ Real-Time Data Acquisition

The system records:

• Applied torque
• Angle of twist
• Torque-angle relationship
• Material stiffness characteristics

Optional software and HMI integration allow live graphical visualization of test results.

✔ Adjustable Specimen Length

A movable measuring jig and sliding dolly enable testing of rods with different lengths, providing flexibility for various experimental requirements.

✔ Safe and Robust Design

The machine incorporates a secure housing and microprocessor-based measuring system that ensures operator safety and reliable operation during testing.

✔ Computer Connectivity

An optional USB interface allows connection to a computer for advanced data acquisition, storage, analysis, and report generation.
