Axial extensometer 7650A Series

high-temperaturecapacitive

High precision extensometer measures axial strains on specimens at temperatures up to 1600 °C (2900 °F). Compatible with materials testing furnaces or induction heating. May be used for strain-controlled, high frequency fatigue tests. Slide mounting system enables mounting to hot specimens in seconds. Epsilon extensometers are COMPATIBLE WITH VIRTUALLY EVERY BRAND OF TEST EQUIPMENT and can be supplied with the correct connector to plug in directly. Operation of these, and all of Epsilon’s extensometers, are VERIFIED TO APPLICABLE STANDARDS SUCH AS ASTM E83 OR ISO 9513 using in-house calibration systems that are calibrated with Epsilon’s laser interferometer system. WITH EPSILON’S 20+ YEAR HISTORY OF SERVICE to the materials testing community, you know we will be there to stand behind our products when your critical application requires it. Model 7650A extensometers measure strains with extremely high precision due to their design features and low strain range. All models are capable of tension and compression strain measurement, and may be used for fatigue testing under fully reversed load and strain conditions at frequencies up to 10 Hz. All 7650A models mount rigidly on the load frame and incorporate slide mounting to bring the extensometer into contact with the specimen. The gauge length is set automatically before mounting on the test specimen, which allows for hot mounting after thermal equilibrium has been reached.
