30Nm Torsion Testing Machine Model MT 130
30Nm Torsion Testing Machine Model MT 130
Sci-tech 30Nm Torsion Testing Machine Model MT 130, is a compact machine, ideal for classroom demonstrations and for safe use by small groups of students. Its frame is a rigid, precision engineered alloy box-section, supported at each end by adjustable feet. It carries two main parts:
- a ‘strain head’ at one end,
- a torque reaction and measurement system at the other end.
The specimens fit between the strain head and the torque reaction and measurement system. The strain head is a 60:1 worm drive reduction gearbox, mounted on a platform. The platform can be moved and locked to any point along the frame. To apply torque, students turn a handle at the input of the gearbox. A keyway allows the output shaft of the gearbox to slide freely along its length. This allows for any change in length of the specimen during the tests and for easy insertion of specimens. An accurate encoder measures the strain (angular movement) at the strain head. The encoder has a digital display and can connect to ‘Sci-tech’ Sci-Cal software & hardware interface. The torque reaction and measurement system includes a torsion shaft supported by bearings. The shaft reacts on a strain-gauged load cell. A digital display shows the force measured by the load cell. The display can connect to Sci-Cal software & hardware interface.

Item Description
Sci-tech 30Nm Torsion Testing Machine Model MT 130, is a compact machine, ideal for classroom demonstrations and for safe use by small groups of students. Its frame is a rigid, precision engineered alloy box-section, supported at each end by adjustable feet. It carries two main parts:
• a ‘strain head’ at one end,
• a torque reaction and measurement system at the other end.
The specimens fit between the strain head and the torque reaction and measurement system.
The strain head is a 60:1 worm drive reduction gearbox, mounted on a platform. The platform can be moved and locked to any point along the frame. To apply torque, students turn a handle at the input of the gearbox. A keyway allows the output shaft of the gearbox to slide
freely along its length. This allows for any change in length of the specimen during the tests and for easy insertion of specimens.
An accurate encoder measures the strain (angular movement) at the strain head. The encoder has a digital display and can connect to ‘Sci-tech’ Sci-Cal software & hardware interface.
The torque reaction and measurement system includes a torsion shaft supported by bearings. The shaft reacts on a strain-gauged load cell. A digital display shows the force measured by the load cell. The display can connect to Sci-Cal software & hardware interface.
Hexagonal drive sockets hold the test specimens. The sockets fit on the gearbox output shaft and the torsion shaft. Sci-tech supplies two different sizes of drive sockets.
For safety, a clear guard protects the user when they perform destructive tests on standard-size specimens.
For increased strain measurement accuracy, use the optional Torsiometer.
The increased accuracy is useful to help find the modulus of rigidity (shear modulus). The torsiometer has a digital display of angular movement, calibrated to the strain angle (in radians).
For quick and reliable tests, Sci-tech can supply the optional Sci-Cal software & hardware interface which gives accurate real-time data capture, monitoring and display, calculation and charting of all important readings on a computer.
