Non-Contacting Video Extensometer

The AVE 2 advanced video extensometer is one of the fastest, most accurate non-contacting strain measurement devices commercially available. Utilizing patented measurement technology, this fully-integrated device easily adapts to the normal fluctuations of environmental conditions in your lab including thermal and lighting variations. The AVE 2 can be used on all types of materials ranging from low-strain metals and composites to high-elongation polymers and elastomers. In addition to ambient testing it can be used with temperature chambers and fluid baths. This device is designed for static and cyclic fatigue testing and meets a broad range of standards, including ISO 527-2ASTM D638ISO 6892-1, ASTM E8, and many more.

Designed to Reduce Operator and Environmental Influences

AVE 2 Advanced Video Extensometer

Non-Contacting Solution

Eliminates the effect of operators on your strain results; producing more consistent and repeatable results. Prevents premature damage to the specimen by measuring strain without touching for the most accurate results.

Patented Cross-Polarized Lighting System

No two labs have the same lighting conditions, and lighting can change throughout the day, which can lead to different results. To ensure the AVE 2 always sees the same image, Instron uses a patented cross-polarized lighting system (US 7,047,819 B2, EP 1,424,547, B1) that’s able to produce repeatable results regardless of your lab’s lighting conditions.

Patented CDAT Fans

Normal laboratory ventilation creates air flows which diffract light, introducing errors that can be as high as several microns. The AVE 2 uses patented CDAT fans (US 7,610,815 B2, and EP 1,424,547, B1) which create a constant air-flow between the specimen and the camera, producing consistent results even if your air conditioner turns on during a test.

One Device to Meet All Your Strain Measurement Needs

Marking Methods

Depending on your application, you can now take measurements using a variety of marking methods — dots, lines, speckle, or even natural patterns.

Advanced Averaging Transverse Strain Measurement for Sheet Metal

AverEdge32 is an optional advanced feature of the AVE 2 that utilizes edge-detection technology to simultaneously measure transverse strain at 32 locations along the specimen gauge length. It then averages them in real time, resulting in a smooth and repeatable transverse strain value, which is essential to calculating the r-value of sheet metal.

Features and Benefits

  • Real-time transverse strain, averaged from 32 gauge widths, provides repeatable transverse strain with even the most demanding materials
  • Improved results repeatability, reducing or eliminating the need to perform any retesting
  • Edge detection eliminates the need for transverse marks
  • Exceeds the requirements of ISO 10113, ASTM E517, JIS 2254 & GB/T 5027 for plastic strain ratio (r-value)
  • AverEdge32 can be seamlessly integrated with any existing AVE 2 currently installed or purchased separately
  • Patent Pending back screen design guides the light away from the operator, reducing fatigue
