Frequently Questions About Strain Gauge Installation and Testing Services

What is a strain gauge?

A strain gauge is a specialised sensor widely used in engineering and materials testing to precisely measure the deformation or strain experienced by an object when subjected to mechanical force or load. It converts mechanical strain into an electrical signal for measurement and analysis.

The core component of a strain gauge is a thin wire, foil, or semiconductor material bonded to the surface of the object being monitored. As external forces act upon the object, it deforms, causing the strain gauge to undergo deformation. This deformation alters the electrical resistance of the gauge material in proportion to the applied strain.

A Wheatstone bridge circuit or other electrical circuits are commonly employed to measure this change in resistance. As the resistance of the strain gauge changes, the electrical circuit detects this variation and generates an electrical signal, typically in millivolts or microvolts, which corresponds to the strain magnitude.

This electrical signal can then be accurately measured, recorded, and analysed, providing valuable insights into the material’s mechanical behaviour, structural integrity, or other critical factors. Strain gauges are indispensable tools in civil engineering, aerospace, automotive engineering, and material science, enabling precise stress and strain analysis in various applications.

What are the types of strain gauges?

There are four types of strain gauges:

Bonded Metallic Foil Strain Gauge: These are the most common and consist of a thin metallic foil bonded to a flexible backing material.

Bonded Semiconductor Strain Gauge: These gauges use semiconductor materials, such as silicon, and are known for their high sensitivity.

Wire Strain Gauge: Wire strain gauges use a fine wire as the sensing element and are suitable for applications with high temperatures.

Unbonded Resistance Wire Strain Gauge: Unlike the bonded wire gauge, this type allows the wire to expand freely under strain, making it suitable for measuring large strains.

What is strain measured in?

Strain is typically measured in microstrain (µε) or simply strain units. One microstrain is equivalent to a strain of one millionth (0.000001) of the original length or size of the material being measured.

How does a strain gauge work?

A strain gauge works based on the principle of electrical resistance change due to mechanical deformation. When strain is applied to the material to which the gauge is attached, it deforms, causing the resistance of the strain gauge to change. This change in resistance is proportional to the applied strain and can be measured as an electrical signal.

How is strain measured?

Strain gauges, once established, require precision in data extraction. Integration into a Wheatstone bridge circuit is typical for this purpose. An excitation voltage is applied, and output voltage is measured across critical points. When structures are undisturbed, the bridge remains balanced, yielding zero output voltage. However, the slightest material deformation alters the gauge’s resistance, throwing the bridge off balance and resulting in voltage change. Due to the minute resistance shift, signal amplification becomes essential, though it introduces unwanted noise. Signal conditioning filters out this noise, ensuring precise and intelligible data and empowering informed decisions in engineering and research.
