File Name: types of strain gauges and their application .zip
Several types of strain gages depend for their operation on the proportional variance of electrical resistance to strain: the piezoresistive or semi-conductor gage, the carbon resistive gage, the bonded metallic wire, and foil resistance gages. The bonded resistance strain gage is by far the most widely used in experimental stress analysis.

The strain gauges are based on the resistive properties of the metal. Upon stretching, the metal material loses or increases its electrical resistance. The strain gauge foil is glued on the material, which will be tested using a specially adapted glue for strain gauges. Due to the correct fit to the material being examined, the strain gauge is bent in the same way as the test material, so it reproduces the stresses.
The main purpose of a strain gauge is to indirectly determine stress and its variation with time, quantitatively. Change in stress is determined by multiplying the measured strain by the modulus of elasticity. We have covered its working principles, characteristics, features, as well as, application areas. Strain GaugeStrain Gage measures the strain amount of contraction as well as expansion caused by external forces on any object. The strain gauge was invented in by Edward E. Simmons and Arthur C.
Chipkin has integration solutions for almost every situation. Click for more information:. Various means like mechanical, optical, acoustical, pneumatic or electrical can be used to measure deformation strain of an object. However, mechanical strain gauges offer certain limitations like low resolutions. Besides they are bulky and difficult to use. These gauges use a light beam, two fine gratings, and a photocell detector to generate an electrical current proportional to strain.
Strain gauges may be used in "smart bridge" technology to detect structural problems early. Strain gauge technology has practically unlimited uses in the field. It can be used to test vehicles, ship hulls, dams, and oil drilling platforms. A simple civil engineering application using strain gauge technology is to install strain gauges on structural components in a bridge or building to measure stress and compare them to analytical models and stress calculations.
The bonded resistance strain gage is an analog electrical sensor ideally suited to the task of measuring surface stains on solid materials. The two most common devices are the popular etched-foil sensor, and the somewhat more exotic semiconductor gage. Strain gages work on the same principle as engineering strain; i. Foundational characteristics, including sensitivity, thermal response, and limiting properties, and use of these sensors in experimental stress analysis applications, including shear measurement, thermal expansion measurement, and principal strain measurement, are reviewed.
A strain gauge was invented by Edward E. Simmons and Arthur C. Ruge, in This invention led to the measurement of a significant amount of strain on various structures. A strain gauge is a type of sensor used in a wide variety of applications to measure the strain of an object. Definition: A strain gauge is one of the imperative devices used in the field of geotechnical engineering to measure strain on diverse structures. By applying an external force, there would be a change in resistance of a strain gauge.
It converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally. The most common types of load cell used are strain gauges, pneumatic, and hydraulic, pneumatic.
Strain gauges are devices that are commonly used by engineers to measure the effect of external forces on an object. They measure strain directly, which can be used to indirectly determine stress, torque, pressure, deflection, and many other measurements. Strain is a dimensionless measurement that is a ratio of the change in length to the original length of an object.
