Technical Specifications
Product Overview
Weldable rebar strain gauge for reinforcement stress monitoring in concrete structures.
Working Principle
Strain gauge sensors operate on the piezoresistive principle where mechanical deformation causes a proportional change in electrical resistance. The gauge consists of a fine metallic foil pattern bonded to a flexible backing material. When the substrate experiences strain, the foil deforms, altering its resistance in direct proportion to the applied strain. Multiple gauges are typically configured in a Wheatstone bridge circuit to enhance sensitivity and compensate for temperature effects. The measurement system provides exceptional resolution capable of detecting micro-strain levels, enabling precise stress analysis and structural health monitoring applications.
Application Scenarios
Fundamental to experimental stress analysis, structural health monitoring, and load measurement across diverse industries. Extensively used in bridge monitoring systems, aircraft structural testing, pressure transducer manufacturing, and load cell production. Critical for validating finite element analysis models, measuring residual stresses, and monitoring fatigue in critical components. The technology supports applications in civil engineering, aerospace, automotive, manufacturing, and research institutions. Particularly valuable for understanding stress distributions in complex structures and validating design assumptions.
