A device that measures the strain in a structural element by measuring changes in electrical resistance of a sensor attached to the element under investigation
A device for determining the amount of strain (change in dimensions) when a stress is applied
A device which experiences a change in resistance when it is stretched or strained
a device that responds to mechanical strain Metal foil gauges are the most common type, responding to strain with a small change in resistance Also vibrating wire types
An extensometer. Device for measuring the changes in distances between points in solid bodies that occur when the body is deformed. Strain gauges are used either to obtain information from which stresses in bodies can be calculated or to act as indicating elements on devices for measuring such quantities as force, pressure, and acceleration
