• Description


• Compact, self-contained, desk-mounting trainer that shows students the use of resistance strain
gauges
• Clear layout with printed graphics to help students understand how strain gauges work
• Includes electronic strain display to show all readings, and automatically calculates strain
• Fully open bridge connection with dummy resistors to allow quarter, half and full-bridge connection
to show students how strain bridge connections work
• Uses strain gauges on three different and popular structures for realistic experiments
• Includes two sets of masses to give each structure a range of stresses
• Extra (optional) specimens are available for more tests in stress and strain of different materials

Specifications
Nett dimensions (assembled):
720 mm high x 760 mm wide x 520 mm front to back
Nett weight (including Strain Display and Weight Sets):
27.5 kg
Packed weight:
41.5 kg
Packed volume:
0.16 m3
Sets of masses:
The large mass set gives weights from 0.5 kg to 10 kg in a
range of units. The small mass set gives weights from 10 g
to 500 g in 10 g units.
Dummy resistors:
Set of three plugs fitted with high accuracy resistors that
match the strain gauges
Strain display:
Multiline display that shows:
• Bridge output voltage (micro-volt)
• Strain reading in micro-strain (me)
• Active arms (gauges)
• Gauge factor
Strain systems:
• Bending system: Four standard gauges fitted to a given
datum on a steel beam, fixed as a cantilever. Nominal
beam cross-section is 5 mm x 20 mm.
• Torsion system: Two sets of identical 45-degree
shear/torque strain gauge rosettes fitted to a torsion
bar. Nominal bar diameter is 10 mm.
• Tension system: Two sets of identical 90-degree ‘Tee’
strain gauge rosettes fitted to a tensile test specimen.
Steel specimen supplied as standard. Nominal tension
specimen cross-section is 2 mm x 10 mm.
