What are Strain Gauges? Strain gauges convert mechanical deformation into measurable resistance changes through the piezoresistive effect. Small resistance shifts are detected using a Wheatstone bridge with amplification and temperature compensation. Common types include linear, diaphragm, rosette, torsion, and dual-parallel gauges—each suited to specific stress directions and materials. Used widely in structural testing, load and pressure measurement, and industrial condition monitoring, strain gauges provide precise data essential for safety, performance, and predictive maintenance across engineering applications.
