The Model LE-05 Laser Extensometer is a precision, wide range instrument specifically designed for accurate, non-contact measurement of strain on various materials under tensile or creep conditions. The instrument is completely self-contained. It is housed in a single, compact enclosure and uses the latest state-of-the-art laser diode technology for high performance, low maintenance operation.
The Model LE-05 includes a digital display, 4-button keypad, analog output, and an RS-232 computer interface, all of which are located on the rear panel. Instrument operation can be local from rear panel or remote via the RS-232 interface.
Designed to handle a wide range of strain measurement applications, the Model LE-05 is extremely simple to operate. It uses a unique scanning laser beam technique to measure elongation entirely from one side of the specimen. This approach eliminates the need for a separate scan receiver unit mounted on the opposite side of the specimen. However, for special applications requiring transmission around or through a specimen, alternative methods can be implemented. In addition, a “high elongation” version of the Model LE-05 is also available for measuring the strain of elastomeric materials.
