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 ...

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 ...

Step onto any household or commercial weighing scale, and suddenly your weight magically appears in neat digital numbers. But how does a simple platform know exactly how much you weigh down to a tenth ...

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 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 ...

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, ...

He is a member of ASTM Committees D30 on Composite Materials, C09 on Concrete and Concrete Aggregates, F16 on Fasteners and E28 on Mechanical Testing. He has also completed various Nadcap, American ...

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 ...
