Strain Measurement Devices

Strain gauge transducers usually employ four strain gauge elements that are electrically connected to form a wheatstone bridge circuit.

Strain measurement devices.

A strain gauge also spelled strain gage is a device used to measure strain on an object. As the object is deformed the foil is. Simmons and arthur c. Choosing a strain sensor and measurement device.

You can measure strain using several methods but the most common is with a strain gage. A strain gage s electrical resistance varies in proportion to the amount of strain in the device. Strain gages are fundamental sensing devices that function as the building blocks of many other types of transducers including pressure load and torque used extensively in structural test and monitoring applications. Ruge in 1938 the most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil pattern.

The metallic strain gage consists of a very fine wire or more commonly metallic foil. The most widely used strain gage is the bonded metallic strain gage. Measuring strain gauge circuits in order to measure strain with a bonded resistance strain gauge it must be connected to an electric circuit that is capable of measuring the minute changes in resistance corresponding to strain. Key advantages of video extensometers are that they do not exhibit any influence on the test.
