Electronic Instrument Research

The LE Model Laser Extensometers are precision, wide-range instruments specifically designed for accurate, non-contact measurement of strain on various materials under tensile or compressive conditions. They may also be utilized for other applications where non-contact measurement is desired. The LE models are completely self-contained and are housed in a single compact enclosure. They take advantage of the latest laser technology in order to achieve high performance with minimal maintenance.

The Model LE Laser Extensometers provide: a digital display; 4 button keypad; analog output; and an RS-232 computer interface; all of which are located on the back panel. Instrument operation may be from the back panel or remote via the RS232 interface.

Although these instruments are designed to handle a wide range of measurement applications, the Model LE Laser Extensometers are easy to operate. They utilize a unique scanning laser beam technique to measure dimension changes from one side of the subject, eliminating the need for a scan receiver on the opposite side. For special applications requiring transmission around or through a specimen or other object, alternate methods can be implemented.
