Noise Control in Strain Gage Measurements
ثبت نشده
چکیده
Strain measurements must often be made in the presence of electric and/or magnetic fields which can superimpose electrical noise on the measurement signals. If not controlled, the noise can lead to inaccurate results and incorrect interpretation of the strain signals; and, in severe cases, can obscure the strain signals altogether. In order to control the noise level, and maximize the signal-to-noise ratio, it is necessary first to understand the types and characteristics of electrical noise, as well as the sources of such noise. With this understanding, it is then possible to apply the most effective noise-reduction measures to any particular instrumentation problem.

متن کاملPattern of Residual Stress in Rail by FEM Analysis and Strain Gage Sectioning Technique
Final step of rail manufacturing is cold rolling straightening process and it hassignificant effects on mechanical properties, straightness, flatness and development of residualstresses. Measurement of residual stresses after straightening process is obligated by railmanufacturing standards. In the present investigation, an attempt has been made to evaluateresidual stresses after straightening ...
متن کاملDigital image correlation techniques for strain measurement in a variety of biomechanical test models.
PURPOSE Previous biomechanical studies have estimated the strains of bone and bone substitutes using strain gages. However, applying strain gages to biological samples can be difficult, and data collection is limited to a small area under the strain gage. The purpose of this study was to compare digital image correlation (DIC) strain measurements to those obtained from strain gages in order to ...
متن کاملUse of Strain Gages for Low Temperature Thermal Expansion Measurements
The use of strain gages for low temperature thermal expansion measurements is increasing, due to it's convenience, and relative accuracy. The determination of thermal expansion with strain gages is complicated by "thermal output strain", a phenomena caused by the temperature dependence of the gage. If thermal output strain is properly compensated , strain gages may be used to measure thermal ex...
متن کاملStrain Gage Measurements on Plastics and Composites
The bonded resistance strain gage, which is central to the topics treated here, was invented in the late 1930's and is now at about the mid-century mark in its career. During the first fifty years of its existence, the strain gage has been applied to virtually every known load-bearing material – ranging from asphalt to zirconium, and missing few, if any, of the letters in between. Whether the m...
