Significant Advantages and Features

Description

Maximum stiffness ensures very accurate high rotation angle measurement resolution over the entire torque range, while high resolution allows excellent repeat accuracy to be achieved.

TorsionLine testing machines are equipped with an electrically interlocked safety device. Testing can only begin if the device is in the closed position.

testControl measurement and control electronics are used for torsion testing.

Principal areas of application for TorsionLine
