Advantage Video Extensometer (AVX)

Flexible, efficient and repeatable non-contact strain measurement

Driven by powerful cameras, processors and software, the MTS Advantage™ Video Extensometer (AVX) delivers unprecedented speed, accuracy and flexibility for non-contact strain measurement. The extensometer recognizes patterns on the specimen to acquire measurement data, which is then processed by MTS TestSuite™ TW software to calculate specimen strain and modulus. Calibration verification procedures ensure continuous and traceable data accuracy.

 

Choose from 16 different quick-attach, interchangeable measurement heads that have predefined gage lengths and integrated LED lights. Simply select a gage length and strain range that meets your testing needs, and use the corresponding materials testing measurement head to accurately determine Young’s modulus, Poisson’s ratio, or select R-Value; or use a general purpose measurement head to measure high elongation materials.

 

This AVX can easily be mounted to any mechanical test system, and its ergonomic design includes a magnetic-return support arm for precise, repeatable video capture. The AVX’s magnetic-return support arm swings out of the way for access to the specimen when using a chamber or test area enclosure.

• Magnetic-return support arm for easy specimen access and precise positioning
• Quick-attach measurement heads supporting a wide array of gage lengths and strain ranges
• Pass/fail calibration verification blocks and software calibration wizard to confirm setup to desired ASTM E83 or ISO 9513 class
• Mounting options on left, right, front or back of load frame

1. Strain ranges assume a distance between the grips of twice the GL, with a centrally positioned gage. Actual strain ranges may be greater or less than these values, depending on gage positioning, grip separation and specimen behavior.

2. Maximum transverse GL and tracking speed is quoted at a measurement rate of 100 Hz.

3. Resolution is based on typical lab performance.

4. For Class B-1, minimum specimen width for transverse gage lengths should be increased by 65%

Note: Working distance is 480 mm.

1. Specified strain ranges assume a distance between the grips of twice the GL, with a centrally positioned gage. Actual strain

   ranges may be greater or less than these values, depending on gage positioning, grip separation and specimen behavior.

2. Maximum transverse GL and tracking speed is quoted at a measurement rate of 15Hz (XT-20x series) and 100 Hz (XT-25x series).

3. Resolution based on typical lab performance.

Note: Working distance is 273 mm and is subject to +/- 5% tolerance.
