| 摘要 |
A strain sensing apparatus for use in the presence of thermal gradients has a strain gauge and resistance temperature gauge in a planar assembly bonded to, deposited on or diffused or implanted in a substrate surface. The apparatus can sense strain and temperature independently and can be used alone or with a plurality of installations in strain gauge based transducers or experimental stress analysis. The output from the temperature gauge can be used accurately to compensate for unwanted thermal effects in the strain gauge and to measure temperature at the strain gauge site. |
