OUR COMPANYStrain measurement for materials testing is our sole business at Epsilon. At Epsilon, we specialize in strain measurement for materials testing. For three decades we have dedicated our efforts to developing top-quality extensometers and calibrators. Located in scenic Jackson, Wyoming, our state-of-the-art facility is where we design and manufacture extensometers for testing all kinds of materials: metals, composites, plastics, ceramics, elastomers, geomaterials, and biomaterials. From fine wire to large rebar, there are models for tension, compression, bend, shear, torsion, bi-axial,...

Interfacing Epsilon extensometers to test equipment. Compatibility All of Epsilon’s strain gaged transducers employ a full Wheatstone bridge design. They are powered by an excitation voltage, typically between 5 and 10 VDC. The output of the extensometer is proportional to the excitation. For this reason the calibrated output is often expressed as a mV/V value. An extensometer with a full scale span of 2.345 mV/V will have a full scale output of 23.450 mV if the excitation is 10V. This span data is provided by Epsilon on each extensometer test certificate. All strain gaged sensors must be connected...

CALIBRATING EXTENSOMETERS WITH EXISTING ELECTRONICS Required for any extensometer you buy, this process can be performed many ways, most of which are quite simple. The most common options are as follows: Using the Epsilon Shunt Calibration System As detailed on the Epsilon Shunt Calibration System page (p. 124), shunt calibration is a very quick and easy way to set your electronics, regardless of brand. Shunt calibration allows you to transfer Epsilon’s calibration to on-site electronics using a two point calibration line fit. The Epsilon Shunt Calibration System is included with all Epsilon...

OUTSTANDING PERFORMANCE FEATURES IN EVERY MODEL Performance Features Rugged construction withstands constant handling and mounting Most models may be left on through specimen failure Light weight to minimize specimen influence Most models operate in both tension and compression Most models are capable of being used in cyclic tests Low operating force, normally less than 40g, with many under 20g Easy to attach to specimens, with quick attach kits for most models Immersible in many non-conductive fluids Initial gauge length accurately established All come with foam lined case Backed by many years...

We are all about service at Epsilon. Each extensometer comes with a full, one year warranty. The warranty covers defects in materials or workmanship for a full year, excluding normal wear and damage from excessive applied force. Each unit is produced under stringent quality standards and is fully tested and calibrated before leaving the factory. Certain items such as knife edges and ceramic rods wear under normal use, and a spare set is included. The modular design of the extensometers allows for easy replacement of damaged parts. Should your extensometer require repair, Epsilon maintains a policy...

Can Epsilon extensometers be left on through specimen failure? Yes. All Epsilon standard extensometers are designed to withstand remaining on the sample through specimen failure. On certain materials, such as high strength metals, knife edges will wear out faster if the extensometer is left on through failure. A spare set of knife edges is included. Frequently Asked Questions Will the extensometer be compatible with my existing electronics? All extensometers in this catalog can easily be shipped with the mating connector already installed, so you can plug right in to your existing electronics....
