Strain gauges are used extensively in sensorsystems to detect forces, moments and deformations. The experimental unitprovides a wide-ranging introduction to the fundamentals of measurement bystrain gauges. Three test specimens for tension, bending and torsion are eachfitted with four strain gauge measuring points. The strain gauges are wired inthe full bridge. The specimens are loaded incrementally allowing for the strainreading to be sequentially monitored. The specimens can be inserted quickly andprecisely into the frame. The strain gauge measuring range is protected by aPlexiglas cover, which also makes it clearly visible for inspection purposes.The measurement amplifier supplies the bridge supply voltage, and displays theload-dependent bridge detuning digitally in voltage values. The digital displayalso features a zero balancing function to allow for any preloading. Thevarious elements of the experiment are clearly laid-out and housed securely ina box. The well-structured instructional material sets out the fundamentals andprovides a step-by-step guide through the experiments.
