WP 500 Torsion Tester, 30Nm Show data sheet (pdf file) Print page
Torsion Tester, 30Nm
Technical Description

  Using this experimental unit, metal test bars are twisted to destruction. The test torque and the angle of twist are recorded during this process. Test bars made of different materials with varying lengths are included. The test torque is applied manually using a hand wheel and a worm gear. 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. The angle of twist is determined using a protractor and and a revolution counter. Commercially available 1/2" square drive sockets, 17mm across flats, are used as specimen holders.
