  • Stress, Strain, and Strain Gages - me.psu.edu

    Stress, Strain, and Strain Gages, Page 2 Strain gage The principle discussed above, namely that a wire's resistance increases with strain, is key to understanding how a strain gage works. The strain gage was invented by Ed Simmons at Caltech in 1936. A strain gage consists of a small diameter wire (actually an etched metal foil) that is attached to a backing material (usually made of plastic) as

  • Strain gauge - Wikipedia

    A strain gauge is a device used to measure strain on an object. 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.

  • How to know a strain gauge's accuracy? | Physics Forums

    Feb 09, 2012 · Hello all. I am looking over various strain gauges as I need to purchase one for my project. However, I have never worked with them before, and I cannot seem to figure out how to know its accuracy (able to detect a certain change in pressure, for example changes of the scale of 1mmHg), seeing as none of the datasheets seem to have that kind of data.

    The pressure to be measured is appilied to the open of the tube. Due to pressure, the tube tends to round off, that is, the dimension changes (strained). As the strain gauge are mounted on the tube, the dimension of the strain gauges also change proportional to the change in dimension of the tube, causing a resistance change of the strain gauges.

  • What is a strain gauge? | Omega Engineering

    A Strain gauge (sometimes refered to as a Strain gage) is a sensor whose resistance varies with applied force; It converts force, pressure, tension, weight, etc., into a change in electrical resistance which can then be measured. When external forces are applied to a stationary object, stress and strain .

    For example, if a uniaxial KFGS gage, of which the gage base including the adhesive layer is 0.015 mm thick, is bonded to a curved surface of 1.5r, the strain gage already receives strain of approximately 5000 μm/m. If the gage factor Ks is 2.00, If the gage resistance is 120, it increases by approximately 1.2 . If the gage is bonded inside ...
