Strain Gauge Principle, Types, Features and Applications

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. Electrical circuits used in the interrogation of strain gages are discussed, along with special considerations and exploitation of specific circuit arrangements for solving unique problems. Potential error sources and correction techniques for both the sensors and circuits are covered. Skip to main content.

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.

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.

Strain Gauge Principle, Types, Features and Applications

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. Field-testing needs differ from laboratory testing needs because of complex shapes, geometry, access, and environment.

Bonded Electrical Resistance Strain Gages

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. This gage consists of a grid of very fine wire or foil bonded to a backing or carrier matrix. The electrical resistance of the grid varies linearly with strain.

Strain Gauge Theory – Types, formulas and applications

The strain gauges are based on the resistive properties of the metal.

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.

What is Strain Gauge : Working and Its Applications

The strain gauges are based on the resistive properties of the metal. Upon stretching, the metal material loses or increases its electrical resistance.
