In 1856, Lord Kelvin observed that metallic conductors subjected to mechanical strain exhibit a change in their electrical resistance. Since that time, engineers have attempted to measure and quantify ...

Many conventional strain gages are similar in appearance to Figure 1. A serpentine pattern etched into a metal foil creates a relatively high resistance in a small space. The foil is bonded to a thin ...

This article appeared in Electronic Design and has been published here with permission. Strain—the response of a material to an applied stress due to an applied force or weight—is an important ...

The miniature-format strain sensors DST20 complement the Baumer portfolio by adding a compact and cost- efficient system for measuring large forces above 10,000 N even in confined spaces. With their ...

The levels of mechanicalstrain most typically measured with strain gauges are very small and precise.Consequently, changes in resistance are also very small and thus cannot bemeasured directly with an ...

Strain gauge sensors measure the strain (displacement) of an object under an applied force. When they are adhesively attached to the object under stress (an applied force), they deform with the object ...

Four high-performance strain-gage sensors have been designed for measuring torque. The full-bridge 0143SD measures torque in any direction, suiting it for use in screw-driving-assembly applications, ...
