When the object under test is subjected to stress, the resulting strain directly deforms the foil, causing its electrical resistance to change. Semiconductor Strain Gauges: Made up of semiconductor materials, these strain gauges exhibit a much higher gauge factor than metallic strain gauges, which makes them highly sensitive.
Types & Advantages The principle of electrical strain gauge is based on measurement of change in some electrical characteristics such as, resistance, capacitance or inductance. In general, resistance type strain gauges are used. It is proportional to strain applied on test specimen.
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. The gauge is attached to the object by a suitable adhesive, such as cyanoacrylate.
In general, resistance type strain gauges are used. It is proportional to strain applied on test specimen. It works on principle of change in resistance of wire with change in strain; resistance is measured by using Wheatstone bridge. The output of Wheatstone bridge can be calibrated to give strain. Simple in construction.
The way it changes over time will reflect the ongoing physical impact of those stress forces on the materials or objects being monitored. The most common format for a strain gauge sensor is a wide strip of flexible backing material containing an embedded conductive element - usually a series of wire leads or foil traces.
The markings outside the active area help to align the gauge during installation. A strain gauge (also spelled strain gage) 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.
