1, interpretation
Sensitive grating: this is the main part of the strain gauge, usually consisting of one or several wires. When subjected to external pressure or strain, these wires will be deformed, thus changing their resistance values.
Substrate: The substrate is the part used to support the sensitive grid, and is usually made of materials with certain mechanical strength and insulation performance.
Covering layer: Covering layer is used to protect sensitive gate and substrate, and is usually made of materials with good electrical insulation performance.
The working principle of strain gauge is based on strain effect, that is, when the strain gauge is subjected to external pressure or strain, its resistance value will change accordingly. This change can be measured and converted into corresponding electrical signal output, thus realizing the measurement of physical quantities.
2. Strain gauge sentence making
The strain gauge is composed of a sensitive grating, a substrate and a covering layer, with high sensitivity and good repeatability.
Strain gauges can accurately measure the strain of objects, so they are widely used in structural health monitoring, pressure measurement and other fields.
Strain gauges have the advantages of small size, light weight and easy installation, and can be conveniently applied in various complex environments.
The working principle of strain gauge is based on strain effect, so its measurement results have high reliability and accuracy.
Strain gauges are widely used in civil engineering, machinery manufacturing, aerospace and other fields, which provide an important guarantee for the safety and stability of various engineering structures.
Function of strain gauge
1, structure and strain
