Strain Gauge Transducers

Strain gauges are used in many instruments that produce mechanical strain because of the affect being measured. In their own right, they are used to measure the strain in a structure being stretched or compressed. The strain gauge element is a very thin wire that is formed into the shape shown. This produces a long wire all in one direction but on a small surface area. The element is often formed by etching a thin foil on a plastic backing. The completed element is then glued to the surface of the material or component that will be strained. The axis […]
