Transverse (Diametral) Extensometers – Model 3575

Epsilon Model 3575 Extensometer

Self-supporting on the test sample, these extensometers will work on any width or diameter specimen from 0 to 25 mm (0-1 inch). They are commonly used for measurement of Poisson’s ratio, for transverse measurements with anisotropic materials like many composites, and for sheet metal testing such as r-value determination. Most often they are used simultaneously with Epsilon’s axial extensometers, and together these extensometers are suitable for measuring Poisson’s ratio per ASTM E132 with most materials and specimens.

These units easily clip onto the sample and are held in place with an integral spring. Rounded contact surfaces maintain the position on the specimen. All are high accuracy strain gaged units, compatible with most test controllers.

Designed for general purpose transverse or diametral strain measurement on axially loaded specimens. This model may be used simultaneously with the Model 3542 axial extensometer.

Model 3575 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.
