How Do You Measure A Strain Gauge?
There are several ways to measure strain. The most common is to use a strain gauge. In laymen’s terms, a strain gauge is a device whose electrical resistance varies in proportion to the amount of strain in the device. The preferred type is a bonded metallic strain gauge. A critical operation in measuring strain is the ability to properly bond the strain gauge to the item under test. The strain gauge has been used for many years. It is a fundamental element used for load sensors, pressure sensors, torque sensors, and also for position sensors. While there are many types of strain gauges, the foil type represents a good example. The principle is simple: The foil used is subjected to various amounts of pressure that will change the foil in defined ways.

These dimensional changes will in turn, increase the ele
