Electronic Extensometer
Electronic Extensometer
An extensometer is used to measure changes in the length of an object. It is useful for stress-strain measurements and tensile tests. In the mining environment, extensometers are used to measure displacements on highwalls. Plotting Displacement vs Time enables geotechnical engineers to determine if wall failures are imminent.

An extensometer is used to measure changes in the length of an object. It is useful for stress-strain
measurements and tensile tests. In the mining environment, extensometers are used to measure
