The advanced video extensometer (AVE) is a high-performance, non-contacting extensometer meets and exceeds the performance of traditional contacting extensometers. The AVE uses a high-resolution digital camera and advanced real-time image processing to make precise strain measurements on material test samples.
With its unique non-contact measurement design, the extensometer has no influence on the specimen, and the possibility of damage due to energy release at failure is eliminated; thus, ensuring accurate test results. The AVE contains no moving parts, so it is never at risk for mechanical wear, which can lead to unreliable results or inaccurate target tracking.
Available with three fields of view (FOV) and transverse strain measurement, the AVE meets diverse testing requirements and is suitable for testing plastics, metals, elastomers, wire, textiles and other materials. Additionally, the ergonomic design provides operators with convenient access to the test area and allows for easy set up.

Extension measurement is one of Zwick Roell´s core areas of competency. The result is a comprehensive range of high class equipment. The product palette is arranged as follows:
Non-contact extensometers with and without measurement marks.
Contact extensometers: Sensor arm extensometers, incremental and analogue clip-on extensometers as well as extensometers for compression and flexure tests.
Advantages of Zwick Roell Extensometers at a Glance
Innovation: Strain measurement is a key technology in the range of test engineering. Zwick is leading in this technology - in the application to extreme damageable materials as well as to tough specimen. The Zwick Roell product program contains extensometers that nobody else can offer.
Selection: Zwick offers a comprehensive selection of extensometers. You get a suitable system for tests on high-extension specimen like elastomers as well as for tests on brittle materials as ceramics. The choice ranges from analogue clip-on extensometers to fully automated universal extensometers.
The operator at the forefront: Zwick Roell extensometers are designed with the operator in mind. They should be as simple as possible to clamp on the specimen and to operate. Automated test sequences from clamping sensor arms to unclamping them after specimen break are available to provide high level performance.
Quality: With the acquisition of an extensometer from Zwick Roell you’ll receive the best quality, this means that the accuracy and high availability of the systems is in the forefront when processing materials of the highest quality.

The forces which arise in industrial processes such a press-fit, punching or crimping often have implications for the quality of the final connection. Such forces can also be measured indirectly in terms of the strain occurring at the surface of the machine structure. This is often simpler than taking a direct force measurement, which requires the sensor to be built into the structure.
Kistler's new Type 9234A… strain transmitter with integral amplifier is fitted to the machine very simply by means of a single M6 screw. Thanks to its high sensitivity, accurate measurements are possible even with extremely rigid machine structures.
The robust transmitter is particularly suitable for use with presses and assembly line robots.

EPSIMETAL, SCAIME’s miniature strain sensor is available either with a high level output signal or with a direct strain gage output. Thanks to a patented mechanical device, installation and removing are made very easy, by means of screws or gluing, and the strain measurement is possible, from very low stresses up to 1000µm/m.
The amplified output version allows, by means of digital adjustment:
- Temperature compensation.
- Adjustable measurement range.
A watertight version is also available.
This is a perfect tool for load and force measurement or monitoring on existing structures and machines.
EPSIMETAL, used with EPSITRAC, offers a specially designed solution for the monitoring of molding machines and presses. It allows the measurement of tie bar stresses on die casting or plastic molding machines, or hydraulic presses. Periodic adjustment, as well as monitoring, is possible, with transportable or permanent installation.

Model 3542 Axial Extensometer - General purpose extensometers for axial tensile, compression, and cyclic testing. Gage lengths from 0.5 to 2 inches (10 to 50 mm) are available in measuring ranges from 5% to 100% of the gage length.
Model 3542L Axial Extensometer - Axial extensometer specially designed for long gage length applications where low level strain measurements are required.
Model 3442 Miniature 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.
Model 3543 Long Gage Length Extensometer - Available in gage lengths from 2 inches (50 mm) and larger with measuring ranges up to 4 inches (100 mm), these extensometers allows the capture of the full stress-strain curve to failure.
Model 3560 Averaged Extensometer - A single integral unit that provides averaged axial strain measurement. This model is also configurable with options for measuring both the averaged axial strain and a transverse strain.
Model 3800 High Elongation Extensometer - Designed for plastics, rubbers, and elastomer testing, these extensometers have very long measuring ranges. Their unique design allows testing to failure and minimizes interaction with the sample.

A single integral unit provides simultaneous lateral (transverse) strain and averaged axial strain measurement. The unit is also available as an averaged axial extensometer alone.
This extensometer is ideally suited for testing anisotropic materials such as advanced composites as well as for general purpose tests like determining Poisson's ratio. The Model 3560-BIA uses a design unique to Epsilon, where the knife edges remain parallel during the displacement. This approach greatly reduces crosstalk between axes and allows use on round or flat specimens with equal ease. These extensometers are very easy to mount. Integral springs hold the unit on the test sample. The parallel multiple flexure design makes these units very durable.

Model 3542RA Averaging Axial Extensometers
Designed for compressive strength tests on rock, concrete and other large compression samples, the 3542RA measures axial strain on opposite sides of the test specimen, and the output is an average of the two readings. Gage lengths from 1 to 8 inches (25 to 200 mm) and measuring ranges from .050 to .250 inches (1.2 to 6 mm) are available.

Model 3590 Digital Electronic Calibrator
Epsilon's calibrator features 50 microinches (0.001 mm) resolution and has full 2 inches (50 mm) of measuring range.The autozero button and digital display greatly simplify calibration of extensometers. It is also available in an ultra-high resolution version with 5 microinch (0.1 micron or 0.0001 mm) resolution.
