The Torsion Of Rods And Tubes Computer Interface set has the same accessories as except Dial Indicator is replaced by Digital Indicator with output. Software is provided.
....
The Torsion of Rods and Tubes is mounted onto a bearing shaft, which is rotated using a thumb wheel and fine worm/wheel gearing mechanism integral to the torsion head. The Torsion of Rods and Tubes comprises of a torsion head at one end and a fixed tailstock at the other, between which are held a variety of torsion specimens in three (3) jaw chucks.
The thumb wheel and gearing applies known torque to the torsion specimen, whilst an integral load cell records the torque force being applied. The signals from the load cell and angular position sensor is fed directly into the Interface. Fine rotational movement, in each direction, of each chuck allows accurate alignment of the Torsion of Rods and Tubes specimens. An angular position sensor is also mounted at the torsion head end to monitor the angular twist of the torsion specimens. Each torsion specimen has profiled ends to match the clamping pattern of the chucks.
