In addition, most of strain gauges are available with extension leadwires preattached at our factory. ALL_2008W. READ PAPER. gauges will determine the type of strain you can measure and the output voltage change. As the object is deformed, the foil is deformed, causing its electrical resistance to change. 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. Print. Certain backing and alloy combinations, along with special construction features, are designed as systems, and given gage series designations. Optical type 3. Strain Gauge Types and Construction Both wire and foil strain gauges take the form of a grid pattern mounted within or onto an insulating carrier, capable of faithfully transmitting the strain from the specimen. lab2. Only types 2 and 3 compensate for the Poisson effect, but all three types minimize the effects of temperature. Among them, a universal strain gage has a structure such that a grid-shaped sensing element of thin metallic resistive foil (3 to 6µm thick) is put on a base of thin plastic film (15 to 16 µm thick) and is laminated with a thin film. The strain gauge should be properly prepared by ideally gluing the strain gauge to the material being tested.
