Torsion Tester 30 Nm- Engineering Lab Training Systems.
Using this unit, metal test bars are
twisted to destruction. The test moment and the angle of twist are
recorded during this process. Test bars made of different materials with
varying lengths are included. The test moment is applied manually using
a hand wheel and a worm drive. Measurement is performed with a strain
gauge torsion shaft, the deformation of which is compensated. The
measurement can be read off directly in Nm on a digital display on the
measuring amplifier. For adaption to different length specimens, the
measurement jig can be slid along the stiff frame. Using a calibration
unit at the start of the experiment, it is possible to generate a
defined torque. The angle of twist is determined using a graduated scale
and and a revolutions counter. Commercially available 1/2" square drive
sockets, 17mm across flats, are used as specimen holders.
