Long Guage Axial Etensometer - Model 3542L

Epsilon Model 3542L Extensometer

Long gauge length extensometers with gauge lengths 100 mm (4 inches) or greater for tensile and compression testing. These units are for long gauge length applications where low-level strain measurements such as offset yield are required.

Epsilon extensometers are COMPATIBLE WITH VIRTUALLY EVERY BRAND OF TEST EQUIPMENT and can be supplied with the correct connector to plug in directly, or supplied with a separate conditioner and amplifier.

Operation of these, and all of Epsilon’s extensometers, are


using in-house calibration systems that are calibrated with Epsilon’s laser interferometer system.

The dual flexure design makes the 3542L very rugged and insensitive to vibrations. These extensometers are designed for testing a wide range of materials including metals, plastics, composites and ceramics. Epsilon’s Model 3543 is recommended for applications requiring long gauge lengths and larger measuring ranges.

The Model 3542L comes standard with Epsilon’s quick attach kit, making it easy to mount the extensometer on the test specimen. The quick attach kit can be removed, allowing mounting of the extensometer with springs or rubber bands.

Model 3542L 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 that is wired to plug directly into the controller. For systems lacking the required electronics, Epsilon can provide a variety of signal conditioning solutions that enable connecting to data acquisition systems or other equipment.

For gauge lengths less than 100 mm (4 inches), see Model 3542.
