A strain gauge is a sensor whose resistance varies with applied force. It measures mechanical strain and converts it into an electrical signal. Engineers use this property to determine stress, weight, and pressure. The gauge factor is a critical parameter in this measurement process. It relates the fractional change in electrical resistance to the mechanical strain. High gauge factors mean the sensor is highly sensitive to small changes. Usually, strain gauges use a Wheatstone bridge circuit for precise voltage readings. This circuit converts the tiny resistance changes into a measurable voltage output. The output is typically expressed as millivolts per volt, or mV/V. Understanding these values is essential for accurate structural analysis and testing.
The standard formula involves gauge factor, strain, and bridge excitation voltage. For a typical bridge circuit, the sensitivity formula is quite straightforward. Output equals bridge factor multiplied by gauge factor and applied strain. We multiply the result by one thousand to convert into millivolts. Microstrain values require multiplying by ten to the negative six power. A quarter bridge uses a factor of zero point two five. A half bridge relies on a factor of zero point five. A full bridge configuration utilizes a maximum factor of one entirely.
