SUCH provides a comprehensive series of metal foil strain gauges designed for precise strain measurement, structural health monitoring, and transducer manufacturing. Operating on the principle of piezoresistive foil deformation, these resistive sensing elements convert minute mechanical surface strains into stable, high-precision electrical signals.The strain gauge lineup includes multiple grid configurations and circuit architectures to meet diverse stress-analysis requirements:Uniaxial Foil Strain Gauges: Designed for single-direction tensile or compressive strain measurements across structural members.Half-Bridge & Shear Strain Gauges: Optimized for shear stress analysis, torque measurement, and bending force evaluation.Full-Bridge & Diaphragm Strain Gauges: Ideal for pressure diaphragms and high-accuracy load cell integration.Available in nominal resistance values of 120 Ω, 175 Ω, 350 Ω, 650 Ω, and 1000 Ω, SUCH strain gauges feature tight resistance tolerances ($\le \pm0.5\%$), gauge factors (sensitivity coefficients) between 2.0 and 2.2, and high insulation resistance ($\ge 10^4\text{ M}\Omega$). With fatigue lifespans exceeding $10^7$ cycles at room temperature, they provide exceptional long-term measurement stability.
