Automatic Breakaway Torque Tester

Imada Automatic Breakaway Torque Tester: instrument description

The IMADA DI-12 Automatic Breakaway Torque Tester can be used to verify the actual tightened torque of a bolt. Torque controlled power tools are set to apply consistent torque, but fasteners are not necessarily tightened to that value if the tools are out of calibration. Breakaway torque tests require a skilled, experienced operator to sense when the bolt begins to breakaway.

The IMADA DI-12 automates this complex operation. Once breakaway torque is measured, power drivers can be reset to the proper tightening torque. DI-12 Automatic Breakaway Torque Tester drives the test piece at consistent speed and detects breakaway torque without overtorquing pretightened fasteners.

Operation Modes
The tester features three measurement modes: TR, PP and PD. TR displays real time torque values. PP Displays peak torque values. PD determines breakway and yield torque (CW only). If breakaway torque value is detected, the green indicator will light, and tester rotation will stop automatically. The DI-12 outputs torque data continuously (in PD mode) to data acquisition software via the USB virtual COM port, enabling the display of breakaway torque profiles.
