Warranty and Service
Each extensometer comes with a one-year warranty covering defects in materials or workmanship, excluding normal wear and excessive force damage. Epsilon Technology ensures quick repair responses and provides spare parts like knife edges and ceramic rods.
Measuring Range Selection
The measuring range depends on factors like signal conditioner resolution and desired dynamic performance. Typical ranges are 5% to 20% for elastic region measurements and up to 100% for more ductile materials.
Advantages Over Crosshead Displacement
Extensometers provide accurate strain measurements by eliminating machine and grip deflections included in crosshead displacement measurements.
Non-Contact Extensometers
Epsilon ONE optical extensometers offer high-resolution, non-contact strain measurement suitable for various materials. They feature instant reset, laser alignment, and are factory calibrated for ease of use. The system supports high-speed data rates and is compatible with environmental chambers.
Features of Epsilon ONE
The Epsilon ONE system includes features like automatic mark detection, laser assist alignment, and a precision telecentric design. It offers real-time digital output and is applicable for many ISO and ASTM standards. The package includes all necessary components for setup and operation.
Model Overviews
The document provides detailed specifications and features of various extensometer models offered by Epsilon Technology Corp. These devices are used for measuring strain in materials during testing, with different models catering to specific testing requirements and conditions.
High-Temperature Extensometers
Models like 3448, 3549, and 7650A are designed for use in materials testing at elevated temperatures, suitable for tensile and fatigue testing in furnaces or induction heaters.
General Features Across Models
All models are designed to be left on through specimen failure, offer high accuracy, and are compatible with various test systems. They include features like replaceable components, high temperature options, and compatibility with Epsilon's calibration systems.
Calibration System
Epsilon's in-house laser interferometer system allows for full calibrator system calibration traceable to NPL standards. The document emphasizes the mutual recognition arrangement (CIPM MRA) that ensures traceability and equivalence of standards labs worldwide, including NIST in the USA and NPL in the UK.
Accreditations
Epsilon Technology is accredited by A2LA to the ISO/IEC 17025 standard and certified by DNV to the ISO 9001 standard. These accreditations ensure the accuracy and consistency of measurements and calibrations.
Warranty
Epsilon offers a one-year limited warranty covering defects in materials or workmanship. The warranty does not cover items subject to wear or damages from improper use. The document outlines the exclusive obligation of Epsilon to repair or replace defective products under the warranty terms.

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...
