Strain Measurement Devices

You can measure strain using several methods but the most common is with a strain gage.

Strain measurement devices.

For nearly 30 years strain measurement devices has built an exceptional level of trust across diverse markets. Strain gauge transducers usually employ four strain gauge elements that are electrically connected to form a wheatstone bridge circuit. 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. Simmons and arthur c.

The metallic strain gage consists of a very fine wire or more commonly metallic foil. 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. The most widely used strain gage is the bonded metallic strain gage.

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. Choosing a strain sensor and measurement device. 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. 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.

A strain gage s electrical resistance varies in proportion to the amount of strain in the device. Key advantages of video extensometers are that they do not exhibit any influence on the test.
