High Temperature Extensometer

High Temperature Extensometer 

It is a major advancement in the design of externally mounted, furnace extensometers. This new extensometer is designed to meet the stringent requirements of strain controlled testing as prescribed in ISO 6892, while introducing many new innovative features that help improve productivity with static testing applications (tension and compression testing) and long term testing such as low cycle fatigue and creep. The overall design reduces any influence from common lab environment vibrations. This unit also incorporates a new feature that allows the user to precisely set the contact force against the test specimen. This allows for even and repeatable contact force, limiting contact force induced errors. This extensometer mounts on a slide bracket (included) that can attach to the load frame of your test system; optional load frame mounting brackets are available. The gauge length is automatically set prior to mounting on the test specimen, which allows for hot mounting after thermal equilibrium has been reached.

The Model 3549 standard temperature version is made for use in split type materials testing furnaces to 1200 °C (2200 °F) and includes water-cooled bracketry. The high temperature option allows use to 1600 °C (2900 °F). These extensometers can be used in carousel systems for rapid high temperature testing.
