Calculate Gauge Factor





Formula

The formula to calculate the gauge factor (GF) is:

\[ GF = \left( \frac{\Delta R}{R} \right) / \epsilon \]

Where:

Definitions

Example

Let's say the change in resistance is 0.5 ohms, the original gauge resistance is 120 ohms, and the strain is 0.002. Using the formula:

\[ GF = \left( \frac{0.5}{120} \right) / 0.002 \]

We get:

\[ GF = 2.08 \]

So, the gauge factor (\( GF \)) is 2.08.

Gauge Factor

Definition: The gauge factor is a measure of the sensitivity of a strain gauge, defined as the ratio of relative change in electrical resistance to the mechanical strain.

Formula: \( GF = \frac{\Delta R / R}{\epsilon} \)

Example: \( GF = \frac{0.002 / 120}{0.001} \)

Derivation of Gauge Factor

Definition: The derivation of the gauge factor involves understanding the relationship between the change in resistance and the strain applied to the material.

Formula: \( GF = 1 + 2\mu + \frac{\Delta \rho / \rho}{\epsilon} \)

Example: \( GF = 1 + 2 \times 0.3 + \frac{0.001 / 1.5}{0.001} \)

How to Calculate Gauge Size

Definition: Calculating the gauge size involves determining the thickness of a material, often used in reference to wires or sheets.

Formula: \( \text{Gauge Size} = \frac{1}{\text{Thickness}} \)

Example: \( \text{Gauge Size} = \frac{1}{0.05} \)
