WP 500

Torsion Tester, 30 Nm

Technical Description

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.
