....Model 3543 Single or Dual Range
Long Gage Length Extensometer ....
Very
small, rugged yet ultra-light weight, these units are
widely used for testing small and delicate samples.
Ideal for many biomedical tests, as well as for wire
and thin sheet materials. Also great for low cycle fatigue
testing where short samples are used.
Weighing as little as 8 grams, these tiny extensometers
also have very low operating force, resulting in little
specimen contact force and influence. All use an Epsilon
proprietary dual flexure design, which makes them very
rugged for their size. Only 0.6 inches tall (15.25 mm),
these extensometers will fit in the small space between
grips which usually results when small test samples
are used.
Features
May
be left on through specimen failure
High
accuracy, with 0.15% linearity.
Rugged,
design for reliable testing.
Separable
design with two halves that come apart prevents damage
at specimen failure.
Replaceable
arms and spacers for ease of repair. This also allows
changing the gage length for different test requirements.
All
units meet existing ASTM and ISO requirements for accuracy.
All will meet ASTM class B-1. All meet ISO 10002-4,
class 0,5.
Interface
with nearly any brand test system.
Hardened
tool steel knife edges are easily replaced. A spare
set comes with every extensometer.
Standard
Quick Attach Kit for quick, one hand mounting to specimens.
Works for both flat and round samples (Flats to 0.5x1
inch (12x25 mm) and rounds up to 1 inch (25 mm) diameter).
Optional arms available for larger samples.
Includes
high quality foam lined case.
High
and low temperature options extend operation from as
low as -265 °C (-450 °F) to +175 °C (350 °F).
Spacers
allow gage length to be changed easily.
