Model 3575 Transverse (Diametral) Extensometer

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.

Self-supporting on the test sample, these extensometers will work on any width or diameter specimen from 0 to 1 inch (25 mm). 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.

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

Features:

May be left on through specimen failure.
Full bridge, 350 ohm strain gaged design for compatibility with nearly any test system.
All models will measure both positive and negative displacements.
All standard units meet existing ASTM class B-1 and ISO 9513, class 0,5 requirements for accuracy.
Includes high quality foam lined case and spare set of tool steel knife edges.
Rugged, dual flexure design for strength and improved performance. Much stronger than single flexure designs, this also allows cyclic testing at higher frequencies.
Easy to mount, with integral springs to keep the extensometer on the sample.
Self-supporting on the specimen

Sheet metal r-value Determination with Models 3575 and 3542.

As shown in the photo, a Model 3575 may be used simultaneously with a Model 3542 axial extensometer to measure r-value. Many researchers are now using only this single lateral measurement for their tests, rather than the older method using three manual measurements.

An alternative unit with dual lateral measurements is the model 3575AVG, which averages transverse readings over two locations.

Model 3575 Available Versions:

ANY combination of measuring range and temperature range listed below is available.

Example: 3575-050T-ST: ±0.050 inches measuring range, standard temperature option (-40°F to 210°F)
