Simultaneous Torsion and Tension Testing  eXpert 81T torsion testing machines from ADMET Inc. are tabletop units with capacities to 200 Nm. The length of the test bed, servo motor and gearing is modified to accommodate varying specimen lengths, capacities and test speeds. A reaction torque transducer is attached to a movable tail stock mounted on a linear slide. The tail stock can be left free-floating or clamped during testing.
The machine is suited for torsion testing bone, catheters, elastomers, fasteners, joints, metals, plastics, shafts, small components and more. Users wishing to perform biaxial tests in tension/compression and torsion have several options. When the tail stock is left free-floating, the user can apply an axial pre-load to the specimen using a weight and pulley arrangement. The machine can also be equipped with a second linear actuator for applying tension and compression forces.
Two closed-loop servo controllers are available for performing static or dynamic tests under torque or angle rate control: the MTESTQuattro—a PC-based controller with software that offers flexibility in control, data analysis, and reporting, and the eP Digital Controller—a standalone unit suited for quality-control testing.
