Question

Gauge factor of strain gauge indicates its:

• A. accuracy
• B. sensitivity
• C. Dead zone
• D. Precision

Hint:

Remember, the gauge factor measures sensitivity, not accuracy or precision. A higher gauge factor indicates higher sensitivity to strain.

Answer 1

The Correct Option is B

The gauge factor of a strain gauge is a measure of its sensitivity, which refers to the ability of the strain gauge to detect small changes in strain. It is the ratio of the relative change in electrical resistance to the mechanical strain experienced by the gauge.
- Accuracy refers to how close the measured value is to the true value, but the gauge factor specifically indicates sensitivity, not accuracy.
- Dead zone refers to a range of input where no response is detected, which is unrelated to the gauge factor.
- Precision refers to the repeatability or consistency of measurements, but the gauge factor directly quantifies sensitivity.
Therefore, the correct answer is sensitivity.
