Epilson’s LE-05 and LE-15 Laser Extensometers are units used in the strain measurement for materials testing. These tools contain a measurement range from 0.3 inches to 5 inches on the LE-05 model, and from 0.3 inches to 15 inches on the LE-15 type. The gauge length of these devices allow high elongation measurements when shorter gauge lengths are used.
These equipment have visible laser light that is simply aimed at the specimen. This laser consists of small reflective tape strips set at the desired gauge length. The analog output and RS-232 interface are easily connected to existing controls or data acquisition systems. In addition, these instruments are suitable for use in chamber calibration unaffected by aiming through the viewing windows.
