AVE2 Advanced Video Extensometer

Non-Contacting Strain Measurement for Dynamic and Fatigue Testing

The Instron AVE2 Advanced Video Extensometer delivers the accuracy and consistency of non-contacting video extensometry in a lightweight, portable design purpose-built for dynamic and fatigue testing. In addition to excellent performance for static testing, the AVE2 is rated for cyclic testing and high-speed monotonic measurement — making it the ideal single strain measurement solution for laboratories running both static and dynamic test programs.

Designed to move easily between systems, the AVE2 can be deployed across multiple Instron ElectroPuls® and servohydraulic testing systems in the same laboratory, offering scientists, engineers, and quality specialists the flexibility to study dynamic material behavior without contacting or influencing the specimen.

Real-time data acquisition rate of 490Hz/s

Key Technologies

CDAT Airflow Technology (Patented)

Typical laboratory environments are subject to variations in airflow — from HVAC systems, nearby equipment, and normal laboratory activity — that can introduce measurement errors of several microns. To maximize accuracy in real-world test conditions, the AVE2 uses Instron's patented Constant Density Air Tunnel (CDAT) technology. CDAT fans generate a consistent laminar airflow between the specimen and camera, shielding the optical path from environmental disturbances and producing consistent results even when air conditioning or ventilation systems are active during a test.

$Anti-Diffraction Airflow System$

Cross-Polarized Lighting System (Patented)

Lighting conditions vary between laboratories and change throughout the day — both of which can introduce variation into extensometer results for the same test type. The AVE2 uses Instron's patented cross-polarized lighting system to ensure the camera always captures a consistent image of the specimen markings, regardless of ambient light conditions. This delivers repeatable results across different shifts, operators, and laboratory environments.

Non-Contacting Measurement

By measuring strain without physical contact with the specimen, the AVE2 eliminates the negative effects of device attachment on test results — including premature specimen damage, attachment variability between operators, and the risk of shock loading damage during high-energy specimen failures. The result is strain data that is inherently more consistent, accurate, and repeatable across the full life of the device.

Flexibility Across Applications

The AVE2 is compatible with a range of environmental chambers, bio-baths, and optional lenses — making it suitable for testing across a wide range of temperatures, environments, and specimen geometries. A single AVE2 can accommodate specimens with multiple gauge lengths and elongation ranges, replacing the need for multiple clip-on devices and simplifying both inventory management and operator training.

In addition to tensile and compression testing, the AVE2 enables measurement and closed-loop control of cyclic strain on a wide range of materials and specimen types — from metals and composites to elastomers, biomaterials, and films.

Compatible with Bluehill® Universal software for static testing and WaveMatrix3 for dynamic and fatigue testing, the AVE2 integrates directly into Instron's testing software environment for seamless data acquisition and test control.

AUTOX750

Automatic Contacting Extensometer

The need for companies to increase specimen throughput — while maintaining high quality standards and safe operating conditions — has created demand for greater speed, reliability, and accuracy in material testing routines. The AutoX750 is an automated long-travel extensometer built to meet that demand with sub-micron precision. With automated gauge length positioning and attachment to the test specimen, operators get a safer, simpler test routine — and companies get faster cycle times while eliminating the variability that comes with manual, time-consuming steps of traditional clip-on extensometers.

Principle of Operation

The AutoX750 integrates with Instron's 3360, 3380, 3400, 5500, 5960, 5980, and 6800 Series electromechanical test systems, as well as LX, DX, HDX, and KPX static hydraulic testing systems, and is controlled with Bluehill^® Universal testing software via USB interface. The software drives an easy-to-use test sequence and setup that facilitates the automated gauge length, reference arm position and opening and closing of the arms before and after testing.

The counterbalanced measuring arms are virtually weightless, thus removing any influence on the material properties under test. The measuring arms are motor driven and will automatically position themselves to the correct position and gauge length every time.

In Bluehill Universal, the AutoX750 provides:

Real-time strain data streamed directly into the test method
Automated modulus, offset yield, and elongation calculations
Logged gauge length and arm position for full test traceability

Application Range

Tensile testing: metals, composites, plastics, and elastomers
Flexure testing: plastics
Specimen shapes: strip, round, hexagonal, and flat
Standard compliance: Conforms to the most rigorous testing standards, including:
- ISO 527-2 and ASTM D638 (plastics)
- ISO 6892-1 (Strain Control Method A1) and ASTM E8 (Strain Control Method B) (metals)
- ASTM D3039 (tensile testing of polymer matrix composite laminates)

AutoX750 Automatic Contacting Extensometer

High Travel - With high accuracy and resolution across 750 mm of travel, the AutoX750 suits a wide range of specimen sizes and gauge lengths.
Counterbalance Technology - Proven counterbalanced technology eliminates external influences on the material under test, producing highly repeatable and reliable measurements.
Automated Test Arms - Built for simplified, safer test routines, reduced cycle time, and high reproducibility. The automated arms attach to the specimen and can remain attached through failure for most materials.
Interchangeable Knife Edges - Swappable knife edges and adjustable clamping forces accommodate a variety of materials and specimen geometries.

Endless Applications

The AutoX750's accuracy and travel make it suited to nearly any material — metals, plastics, and composites alike. Use it to determine modulus, offset yield, non-proportional plastic elongation to failure, and r- and n-values for sheet metals.

AutoXBiax — Axial and Transverse Strain Measurement

Catalog No. 2665-751

The AutoXBiax is an automated, high-precision measurement device that captures axial and transverse strain simultaneously. Built on the same high-accuracy optical measurement system as the AutoX750, it's purpose-designed to measure plastic strain ratio (r-value) for steel — exceeding current standards including ISO 10113, ASTM E517, and JIS Z 2254.

The AutoXBiax is compatible with the 3382A, 5960, 5980, and 6800 Series systems.

AutoX750 vs. AutoXBiax — Which Do I Need?

	AutoX750	AutoXBiax
Strain Measured:	Axial only	Axial and transverse (simultaneously)
Best For:	General tensile/flexure testing across metals, plastics, composites, elastomers	r-value determination for sheet steel
Key Standards:	ISO 527-2, ASTM D638, ISO 6892-1, ASTM E8, ASTM D3039	ISO 10113, ASTM E517, JIS Z 2254

AlignPRO Alignment System

Testing Accessories » AlignPRO Alignment System » Page 4

For applications with specific alignment requirements, the AlignPRO™ system can be used to control both concentricity and angularity in your load string to optimize alignment. The system consists of an AlignPRO Fixture, mounted between the load cell and the load frame, which is used to make adjustments to concentricity and angularity.

AlignPRO Software monitors the output from strain gauges mounted on either flat or round alignment cells. These outputs are used to calculate bending due to angular and concentric alignment errors, so you can make adjustments with the AlignPRO Fixture while monitoring their effect on bending in real time.

Need to verify alignment to ASTM E1012 or Nadcap requirements? Instron also offers alignment verification services.

View Specifications View Jaw Faces

Principle of Operation

The wedge action principle of these grips allows them to be tightened onto a specimen without altering the vertical position of the faces in relation to the specimen. This is accomplished by a design, which moves the grip body to close the faces. This feature makes it possible to pre-select the exact point at which the specimen will be held with consistent gauge length and no compressive force applied which may cause specimen buckling.

A strong clamping force can be applied to materials that are difficult to hold through a high mechanical advantage achieved by the tightening mechanism. The grip faces are spring loaded against a shoe which is in a fixed position in respect to the testing frame holding mechanism, only a light initial gripping force needs to be applied to the specimen. As the grip is tightened, it's frame is drawn up and the inclined sides push against the matching side of the faces which move laterally against the specimen. A shoe incorporated to the driving shaft prevents the faces from moving.

The open front design of the grip frames allows faces to be easily interchanged as well as easy specimen loading. Because the faces are held in fixed position, there is no recoil, or loosening, when the specimen ruptures and if an extensometer is attached, it will remain in place.

Principle of Operation

The self tightening grip uses an eccentric roller type clamping action. A single fast action lever reduces the time required to load specimens. Specimen insertion is extremely easy and the spring pressures of the roller bracket gives a positive non-slip action gripping force. This is sufficient to hold the material until a load is applied. The follow up action of the roller while under test prevents the specimen from slipping out of the grip as the load increases.

Dynamic Strain Gauge Extensometer

The 2620 Series dynamic strain gauge extensometers are accurate lightweight units used for direct measurement and closed-loop control of strain in a variety of static and high frequency cyclic materials testing applications. Tensile, compressive, low and high cycle fatigue testing, creep and stress relaxation as well as straight line (ramp) testing may be performed with the 2620 series dynamic strain gauge extensometer to an extensive range of national and international standards.

Principle Of Operation

The 2620 Series extensometers are strain gauge units. The flexural element is a special alloy operating beam with fatigue certified foil gauges bonded to it. The gauges are arranged in a fully active four-arm Wheatstone bridge circuit. It is mounted in a lightweight frame and accurately follows the strain amplitudes applied to it. Variations of gauge length and percentage strain levels may be achieved by the addition of gauge length extenders. Integrated mechanical stops limit the amount of overtravel in the extensometers, enabling them to survive specimen rupture without damage.

Application Range

The 2620 Series extensometers are designed for use with metals, composites, plastics, wood and other materials exhibiting total strains up to ±50% of the original gauge length. They are immersible in a range of fluids (acetone, mineral and silicone oils, alcohol and similar cooling/heating fluids) and can be quickly and easily calibrated.

WEBBING CAPSTAN TENSILE GRIPS

For Testing High-Strength Textile Materials

Webbing capstan grips are designed to permit faster, easier testing of seat belts and other high strength belts and tapes. Based on the capstan principle, these grips minimize slippage and jaw breakage effects, and permit the predetermination of specimen length while allowing for quick, convenient loading.

Request A Quote

Principle of Operation

These webbing capstan grips incorporate an ingenious double capstan design which provides fast, easy loading with a gripping action that results in proper breaks in the full gauge length of the specimen. The key to the ease of loading is the use of an inner and outer capstan. The specimen is loaded simply by inserting one end into the groove of the inner capstan and cranking it through 360 degrees. Gripping efficiency is also greatly increased because the surfaces of both capstans are utilized.

Translation and Clamping Stages

Testing Accessories » Electronics and Microelectronics Testing Systems and Accessories » Translation and Clamping Stages » Page 4

Translation and clamping stages are used to precisely position and align a test specimen beneath the actuator, ensuring accurate setup before testing begins. These stages provide secure, adjustable positioning for microelectronic circuit boards and small components, helping maintain proper alignment and stability within the testing system for reliable and repeatable results.

PCB Clamping Stage

Catalog No. 2860-200

The clamping stage may be mounted directly to the base of a testing machine in order to provide accurate adjustment and indexing of the specimen position during testing. In a typical test configuration the assembly under test would be mounted in the PCB clamping stage fitted to an X-Y translation stage or directly to the base of a test machine and a lead pull grip would be mounted below the load cell on the moving crosshead or actuator.

Overview
Capacity	500 N
Clamping Span	Adjustable: 0 to 150 mm

Theta-X-Y Manual Translation Stage

Catalog No. 2860-101

The Theta-X-Y manual translation stage provides the facility to precisely position and align a test specimen below the actuator (two axes). Theta (angle) and X-Y axes are also adjustable via digital micrometers. The rotary axis can be adjusted via a micrometer and has a vernier scale readable to 5 ft. The X-Y axes micrometers have a resolution of 1 micron. The axes are arranged with the angle stage at the base, with the X-Y stage on top. This allows the test platform to be oriented with the X-Y axes referenced to the specimen. Typical applications include lead pull and component pull off tests on microelectronic devices and PCB’s.

PNEUMATIC CORD AND YARN TENSILE GRIPS

For Testing Fiber, Cord, Yarns, and Fine Braided Wires

Textile Cord, Yarn, and Rope Tensile_Grips

Pneumatic cord and yarn grips provide a convenient method for clamping fiber, cord, yarns and fine braided wires to reduce the problem of jaw breaks associated with testing these materials. A specially designed horn with a smooth finish and a contoured surface with a graduated cam allows for easy loading and a stress reduced clamping area on the specimen. The clamping mechanism can be activated either automatically or through a foot switch. This allows hands-free grip operation enabling the specimen to be held with both hands for easy loading. Pneumatic cord and yarn grips provide a selectable clamping force to accommodate different materials and excellent follow-up action which compensates for decay of the holding force due to specimen creep.

Principle of Operation

Where the gripping area of mono-filaments, cord and yarn is small in relation to the strength, normal techniques using standard grip faces usually result in specimen failures adjacent to the jaw faces. The pneumatic cord and yarn grips have been designed specifically to overcome the problem of specimen failure by incorporating a capstan design which evenly distributes the gripping force over the surface of a curved half capstan through friction.

In addition, the pneumatically cushioned gripping force applied to the ends of the specimen compensates for the decay of force due to specimen creep.The pneumatics activate a moveable face, which acts upon a contoured fixed gripping face. This serves as a capstan and provides support for the specimen, making the transition from the free stressed length of specimen to the rigidly clamped portion gradually rather than abruptly, thus minimizing breakage of the specimen adjacent to the jaw face. The capstan also incorporates a polished guide horn, which assists in rapid specimen loading. The polished finish prevents damage to individual fibres during specimen insertion.

The specimen is placed over the top of the horn and slides down to the proper gripping position on the contoured clamp. The grips may be closed or opened by a pneumatic footswitch for hands free operation. An automatic air kit is also available for hands free, automated, and pretension testing via software or system default settings.
