The AdvantageTM Video Extensometerdelivers confidence in non-contact strain
measurement. The ergonomic design
integrates a magnetic-return support arm
for precise, repeatable video capture, andcalibration verification procedures ensure
continuous and traceable data accuracy.
Driven by powerful cameras, processors
and software, the MTS Advantage
Video Extensometer (AVX) delivers
unprecedented speed, accuracy andflexibility for non-contact measurement.
The extensometer recognizes patterns on
the specimen to acquire measurement
data, which is then processed by MTS
TestSuiteTM TW software to calculate
specimen strain and modulus.

Choose from 16 different quick-attach,interchangeable measurement heads thathave predefined gage lengths. Simply
select a gage length and strain range thatmeets your testing needs, and use thecorresponding materials testingmeasurement head to accurately
determine Young’s modulus, Poisson’sratio, or select R-Value; or a general
purpose measurement head to measurehigh elongation materials.
The AVX’s magnetic-return support arm
swings out of the way for access to thespecimen when using a chamber or testarea enclosure. Also, the video extensometercan easily be mounted to any mechanicaltest system, and the LED light is integrated
into the measurement head.

Advantages of Video Extensometry
Because they do not touch the specimen, non-contact extensometers work well when
specimens are thin or brittle, have irregular surfaces, require high-temperature orsubmerged environments or tend to release a great deal of energy at failure.

BU ILT IN FLEXIB ILITYTA KE M U LT IPL E M E A SU RE M E NT SInterchangeable measurement heads can replace dozens ofextensometers in your laboratory. Buy multiple measurement
heads with your initial purchase or add them as laboratoryneeds change.

Unlike other strain measurement technologies, the AVX allows
users to take up to 200 measurements in real time with one
instrument. Options allow users to upgrade to a more advanced
package to measure strain, Poisson’s ratio, rotation or shear strain.

When testing a specimen sample that is fragile, brittle or irregularly
shaped, non-contact extensometry prevents damage caused by
the contact forces of a clip-on extensometer.

The AVX reduces the chance for operator error in placing theextensometer on the specimen, and allows repeatable measurements
to be taken after the physical test is complete in post process mode.

Put the MTS Advantage Video Extensometer to Work for You
The AVX allows for non-contact multi-point measurement of strain, rotation, anddisplacement by using pattern recognition and sub-pixel interpolation to measureexact displacements of selected points on a video image.

From testing nanowires to high elongation plastics, you canconfigure your AVX to test virtually any gage length with thecorrect measurement head. Additionally, AVX avoids common
tensile testing problems like slipping, adding stress concentrationsor breaking during high-energy fractures.

High-precision deflection measurements may be taken during a
multi-point bend test. Point deflection measurements may betaken for the rollers or specimen, or strain can be directly measured
from the surface in tension.

Compression platens often inhibit access to the specimen, but
unlike contacting methods the AVX only requires line of sitethrough to the specimen. Without specimen contact, there islittle risk of damage to the strain measurement device.

22D multi-point tracking allows for direct measurements of shear
strain. Direct measurements can be taken through measuring thechange in angle between three points. Shear modulus measurements
can be taken using these methods for v-notch or short beamspecimens of any size using the appropriate hardware and minimal
specimen preparation.
