Strain Measurement Devices

The most widely used strain gage is the bonded metallic strain gage.

Strain measurement devices.

A strain gauge also spelled strain gage is a device used to measure strain on an object. Non contacting video a video extensometer is a non contacting extensometer that can measure deformation by tracking the movement of two attached markers on the specimen using high resolution digital camera technology. Key advantages of video extensometers are that they do not exhibit any influence on the test. Choosing a strain sensor and measurement device.

Simmons and arthur c. As the object is deformed the foil is. You can measure strain using several methods but the most common is with a strain gage. The metallic strain gage consists of a very fine wire or more commonly metallic foil.

Whether it is a noninvasive flow sensor for medical device manufacturers a rugged pressure sensor for oil and gas exploration or a miniature load cell for aerospace applications our customers need the utmost confidence in the. 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. The gauge is attached to the object by a suitable adhesive such as cyanoacrylate. 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.

A strain gage s electrical resistance varies in proportion to the amount of strain in the device. For nearly 30 years strain measurement devices has built an exceptional level of trust across diverse markets.
