- The Strain Gauge Trainer contains everything needed to show students how resistance strain gauges work on three different structures. Strain gauges are used extensively in sensor systems to detect forces, moments and deformations. Students use the small set of masses to load the bending and torsion systems, and the large set of masses to load the tension system. Students can also connect and compare the performance of quarter, half and full- bridge strain gauge connections for each structure.
- The bending system uses gauges to measure direct tensile and compression strain. The torsion system shows the use of shear/torque strain gauges. The tension system shows the use of two gauges at right angles in a ‘Tee’ rosette. The tension system also finds and proves Poisson’s ratio for tensile and compressive strains in metals. The strain display includes a set of high-accuracy dummy strain gauge resistors (plugs) and controls. These allow the student to connect the strain gauges on the structures as quarter, half or full-bridge networks. The strain display works with and gives correct readings for all bridge connections and different gauge factors.
- The unit has Touch LCD display for visualization of process and the measurements. The Unit is also connected to Software for computer connectivity and data analysis. The Touch screen and computer software is included in the package.
