3542 Axial Extensometers General purpose extensometers for axial tensile, compression, and cyclic testing. Gauge lengths from 10 to 80 mm (and 0.5 to 2 inches) and full scale measuring ranges from 5% to 100% strain. Model 3542 with 25 mm gauge length Model 3542 with 0.5 inch gauge length and ±25% measuring range These extensometers are designed for testing a wide range of materials, including metals, plastics, composites and ceramics. All will perform both tension and compression strain measurement. The dual flexure design makes them very rugged and insensitive to vibrations, which permits Model 3542 with 25 mm gauge length and higher frequency operation. ±10% measuring range They come standard with Epsilon’s quick attach kit, making it possible to mount the extensometer on the test specimen quickly and easily with one hand. The quick attach kit can be removed, allowing mounting of the extensometer with springs or rubber bands. The Model 3542 extensometers are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers. Most often they are connected to a test machine controller. The signal conditioning electron­ ics for the extensometer is typically included with the test machine controller or may often be added. In this case the extensometer is shipped with the proper connector and wiring to plug directly into the electronics. For systems lacking the required electronics, Epsilon can provide a variety of solutions, allowing the extensometer output to be connected to data acquisition boards, chart recorders or other equipment. For gauge lengths 100 mm (4 inches) or greater see Model 3542L. See the electronics section of this catalog for available signal conditioners and strain meters. Extensometers for Composites Compression Testing Model 3542 configured for a very large specimen diameter See the Model 3542 extensometer videos Models 3542 and 3442 extensometers can be furnished to clip directly onto composites compression fixtures, such as for ASTM D695. These use specially made quick attach kit wire forms for the test fixture. Consult the factory for specifics. Also see the Model 3442 miniature extensometer. Rubber band and spring attachment options included with Models 3542 and 3442 • Model 3542 mounted on a D695 compression fixture for composite materials Standard quick attach wire forms included for round and flat samples Visit our website at www.epsilontech
