Semiconductor Strain Gages have large temperature coefficients of resistance making single gage strain measurements difficult unless used at a constant temperature. If α = 1/300 °C− 1, approximate value for many pure metals, the apparent deformation is in the order of 1/600, which would correspond in steel to a stress of approximately 700 Nmm−2, the order of maximum allowable stress; the magnitude of the error can be reduced considerably by using an appropriate material for wire (for the constantan α ≈ 0 °C−1). Invented by Edward E. Simmons and Arthur C. Ruge in 1938, the most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil pattern. A semiconductor gauge produces an output signal approximately 75 times greater than a foil strain gauge, which allows for measurement of smaller loads.
