What is Gauge Factor?

The gauge factor (GF) of a strain gauge is a measure of the sensitivity of the gauge. It is defined as the ratio of the relative change in electrical resistance to the mechanical strain applied to the gauge.

How to Use This Calculator

  1. Enter the gauge sensitivity (G) in the first input field. This is typically provided by the strain gauge manufacturer.
  2. Enter the piezoresistive coefficient (π) in the second input field. This coefficient indicates how much the resistance of the material changes with strain.
  3. Click the "Calculate" button to compute the gauge factor.
  4. The result will be displayed in the "Gauge Factor (GF)" field.

Working Principle

The gauge factor is calculated using the formula: GF = G / π, where G is the gauge sensitivity and π is the piezoresistive coefficient. This formula shows how the electrical resistance of the strain gauge changes in response to mechanical strain.

Applications

Gauge factors are crucial in various applications such as:

  • Measuring strain in mechanical structures
  • Engineer stress analysis
  • Sensor design and calibration
  • Industrial monitoring systems
