SUNDOO Full-Automatic Torque Tester STW

The STW-500 Full-Automatic Torque Tester is a servo-driven system designed for precise torque and angle measurement with controlled low-speed rotation. It provides high-accuracy torque testing with real-time curve display and programmable automatic test modes.

  • High-precision torque and angle sensors
  • Digital servo drive with low noise and high stability
  • Dual speed modes: fast approach and low-speed sampling
  • Automatic return to start position after test

Description

The STW-500 Full-Automatic Torque Tester is built for high-precision torque and angle testing using a mechanical drive combined with advanced electronic control technology. It delivers stable, low-speed rotational loading with fine speed adjustment, making it suitable for applications that require controlled torque application and detailed angle monitoring. With a torque capacity of 500 N·m and wide angle measurement range, the system supports detailed performance verification and durability testing of torque-sensitive components.

The tester features a high-precision sensor and a low-noise digital servo drive system to ensure accurate and repeatable results. Its touchscreen TFT display shows peak value, real-time value, and torque curve simultaneously, allowing operators to monitor the full test process. Multiple test modes, automatic return, data storage, and auto power-off functions improve workflow efficiency and repeatability in laboratory and industrial test environments.

Features

  • Without any action, automatic off mode, with freely adjustable time
  • High precision sensor, promising test accuracy
  • High-efficiency digital servo drive system with minimal noise and outstanding stability auto-return to starting point after test completion
  • High-speed approach and low-speed collection are the two speed modes.
  • Option for three units: N, kgf, lbf, automated exchange
  • Keep track of 10 test results and 3 groups’ curve tests
  • Various test modes for various test requirements manually controlled torque continuous angle Peak/real-time value/force curve
  • display at the same time on an 800*480 pixel, TFT colourful screen with touch capabilities, allowing you to keep an eye on the test procedure.
