Gage factor strain
WebAug 29, 2024 · Strain gauges are “ratiometric” transducers – their signal output is proportional to the supply voltage used to power them. Strain gauges work with a wide variety of voltage supplies. Typical supply voltages range from one volt to ten volts. But what is the “best” voltage excitation level to use when measuring a strain gauge? WebJan 7, 2024 · Gauge Factor is defined as the ratio of per unit change in resistance to the per unit change in length. This can be mathematically written as, G f = (ΔR / R) / (ΔL / …

WebHere are some typical values for resistance, strain gage factor, and strain, along with the predicted values of change in resistance: o The electrical resistance R of a commercial strain gage (with no applied strain) is typically either 120 or 350 . o The most widely used commercially available strain gages have R = 120 . WebTo determine the gage factor, a strain gage is mounted on the lower surface of a beam as shown in Fig. E2.2. The initial resistance of the gage is 120.1Ω. At a load P of 6745 lb, the resistance of the gage is increased to 120.8Ω. What is the gage factor? Assume that E = 30, 000 ksi, L = 4.0 in., L 1 = 10.0 in., b = 0.5 in., and h = 2 in.
