Product Description

Computer Controlled KNDW Series Material Torsion Testing Machine

Product Description

Application:

This Series Torsion Testing Machine or Twist Testing Machine are used to determine the torsional properties of various

components – from fasteners to biomedical devices.

KS offers a full range of torsion load frames range from 100 to 30,000 Nm, higher capacity and other longer length models

are available upon request.

These uniquely superior torsion testers provide loading and weighing capabilities in both directions of rotation. This feature

makes it possible to conveniently determine not only the ultimate torque load of a specimen, but how that specimen behaves

under conditions of continuous or intermittent torque loading in both directions. Essentially, each torsion tester comprises a

variable speed drive loading system and a digital control and indicating system in a fixed unit.

The weighing head with its strain gage torque sensor is mounted on a moveable unit which can positioned

on the rails to accommodate specimes of varying lengths.
