Monotonic Metric Gage Length Extensometers for Tensile Testing
MTS Fundamental Series 635 Extensometers are ideal for measuring strain in tension applications. The design is optimized for monotonic testing with reliability, durability an affordability in mind.
Like all MTS extensometers, the 635 series feature our unique design of proprietary strain gaged elements using a special heat treated alloy. They are designed with a ground profile, dual-member flexure that provides for very low activation force with excellent strength. The design assures true center-point bending resulting in low hysteresis and exceptionally accurate strain readings.
Mechanical stops on these extensometers make it possible to leave them attached through specimen failure without damaging the unit. They also feature a zero-set pin for accurate and consistent determination of the initial gage length.
MTS Fundamental Series 635 Extensometers come standard with hardened, replaceable knife edges for flat and round specimens. These units come standard with patented MTS Quick-attach springs which make attachment to specimens fast and easy. Each extensometer is packed in a storage case containing the instrument and attached cable.
