High-temperature extensometer 3549 series

strain gaugefor furnaces

Suitable for tensile and fatigue testing when using split type materials testing furnaces or induction heaters. This model can be mounted on a hot test sample in a few seconds. With low sensitivity to vibrations, this innovative high-temperature extensometer is ideal for the demanding requirements of strain-controlled, elevated temperature uniaxial tension and fatigue testing. 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. Epsilon extensometers are COMPATIBLE WITH VIRTUALLY EVERY BRAND OF TEST EQUIPMENT and can be supplied with the correct connector to plug in directly, or supplied with a separate conditioner and amplifier. 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. The Model 3549 is a major advancement in the design of externally mounted furnace extensometers. It is designed to meet the stringent requirements of strain-controlled testing as prescribed in ISO 6892, ISO 12106 and ASTM E606, while introducing many innovative features that improve productivity and performance for static tensile testing, long-term testing such as low cycle fatigue and creep, and other applications requiring small strain measurements. The overall design reduces influence from common lab environment vibrations, thermal noise, and thermal drift. It also allows the user to precisely set the contact force against the test specimen.
