High-temperature extensometer 3448 series

axial

Designed for use with furnaces and induction heating systems, these extensometers use Epsilon’s exclusive, self-supporting design. A wide range of options cover most testing applications. Epsilon brought the first self-supporting, axial furnace extensometer using ceramic fiber cords to market in 1995. Epsilon’s engineers performed evaluations of cord positions in both the standard ceramic fiber cord attachments (elevated above the ceramic rods) and the induction heater version (rods and fiber cord attachments parallel to one another), and found the performance of each to be identical. Operation of these, and all of epsilon’s extensometers, are verified to either ASTM E83 or ISO 9513 standards 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. Epsilon developed this unique high temperature extensometer for testing metals, ceramics, and composites at the high temperatures produced by furnaces and induction heating systems. A combination of features make these extensometers easier to use and better in performance than other similar high temperature extensometers. The units are held on the specimen by light, flexible ceramic fiber cords. These make the extensometer self-supporting on the specimen. No furnace mounting brackets are required. The side load on the test sample is greatly reduced because of the self-supporting design and light weight of the sensor.
