Axial Etensometer - Model 3542
General purpose strain gage extensometers for axial tensile, compression, and cyclic testing. Gauge lengths from 20 to 80 mm (and 0.8 to 2 inches) and full scale measuring ranges from 5% to 100% strain.
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 higher frequency operation.
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.
Model 3542 extensometers are applicable for testing with the following standards:
• ISO 6892-1, 527-2, 527-4, 527-5, 10113
• ASTM E8, E9, D3039, D638, A370, D3552, E517, E646
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 with electronics for a strain channel, and Epsilon will equip the extensometer with a compatible connector wired to plug directly into the controller. For systems lacking the required electronics, Epsilon can provide a variety of solutions for signal conditioning and connection to data acquisition systems or other equipment.
For gauge lengths less than 20 mm (0.8 inches), Epsilon recommends the more compact Model 3442. For gauge lengths 100 mm (4 inches) or greater see Model 3542L.
