videoXtens Extensometer

videoXtens is used for optical measurement of extension on contact-sensitive and highly elastic materials.

videoXtens is used for optical measurement of extension on contact-sensitive and highly elastic materials. This extensometer provides non-contact measurement of tensile, compression, and flexural deformations of all types of plastics, metals, rubber, composites, and films, as well as two-dimensional point displacements within a matrix, e.g. on components.

It is also suitable for determining change in width, r-values to ISO 10113 and ISO 10275, and offset yields in tensile tests to ISO 6892-1. Whenever international standards require a high degree of precision, videoXtens is the perfect solution. Operator influence is virtually eliminated and consistent test results are assured.

Key Advantages and Features

Simple operation

  • Automatic gauge-mark recognition and acquisition of initial gauge-length L0.
  • Tamper-proof: anti-tamper paint is applied to the lenses for the complete system so nothing can be adjusted. An important requirement for reliable test results.
  • Easy alignment to the specimen: videoXtens is centrally aligned to the gauge marks via the connection to the crosshead (option).
  • Compensation for different specimen thicknesses plus testing shear specimens.
  • Wear-free system = low-maintenance. The systems also feature an extremely long service life.
  • Connection to non-ZwickRoell machines via ±10V interface.

High accuracy and repeatability

  • Extensometer mounted using stable, low-vibration holders.
  • Housing provides protection against dirt and dust and inadvertent loss of adjustment of components.
  • Exact synchronization of all measurement channels.
  • Specially developed lighting provides high-quality contrast ratios on the specimen at all times, even with varying environmental conditions.
  • Industrial-quality cameras and high-quality, low-distortion lenses
  • ZwickRoell extensometers exceed the requirements of the standards and are calibrated over the entire measurement range in their individual accuracy class to ISO 9513.
  • videoXtens 2-120 HP is calibrated with the first calibration point from as early as 20 µm in Accuracy Class 0.5, ISO 9513.
  • Additional calibration data-points for traceable, standard-compliant Young's modulus determination on plastics to ISO 527 (e.g. via additional calibration value at 25 µm) with videoXtens 2-120 HP.

Automatic centering

  • videoXtens tracks at half crosshead speed via the connection to the crosshead, keeping the testing operation automatically in focus and making optimum use of the measuring range (larger measuring range possible).
  • This results in increased system measurement accuracy; the gauge marks shift less in the image and are captured in the center of the lens (low lens distortion).

Testing without gauge marks

  • The innovative pattern-recognition algorithm allows virtual gauge marks to be applied to the specimen. The gauge marks can be changed retrospectively and re-calculated (Test Re-Run option). It doesn't get any more convenient!
  • The essential requirement is for a pattern on the specimen - either a natural pattern due to a structured surface or an artificial pattern which can quickly be applied using a marker spray or by stippling.

videoXtens 2-120 HP

videoXtens 2-120 HP includes two high-resolution cameras. Their overlapping fields of view are combined into one large field via ZwickRoell array technology. Markings leaving the field of view of one camera are automatically transferred to that of the next camera. This provides a greater field of view with high resolution.

The flexible tunnel can be extended or retracted to suit individual requirements. By minimizing environmental influences it creates the conditions required for a low-noise signal. It also contains integrated LEDs which provide uniform specimen illumination.

The system can easily be attached to a ZwickRoell temperature chamber via a tunnel adapter. This results in a closed system, minimizing signal interference due to air currents.

videoXtens 1-32 HP/TZ

The videoXtens 1-32 HP/TZ includes one camera, one green LED light source for measurement at very high temperatures, and one telecentric lens for reduction of distance changes between the lens and specimen. The non-contact extensometer optically measures deformations in different environmental conditions in a temperature range up to 1,400°C. Based on the measurement principle, application of temperature-resistant measurement gauges is necessary.

For tests in combination with temperature chambers and high-temperature furnaces, the videoXtens 1-32 HP/TZ is equipped with an adjustable tunnel. This tunnel minimizes interfering factors such as air currents between the camera and specimen.

Ensayo en acero corrugado con el extensómetro videoXtens de 2 cámaras

Las opciones de software Test Re-Run y el desarrollo del alargamiento permiten medir toda la longitud de la probeta y recalcular posteriormente la deformación.

Software Options 

testXpert III testing software offers various options for precise, traceable non-contact extension and strain distribution measurement. 

Test re-run

The optional Test Re-Run module enables retrospective recalculation of strain using an image series recorded during a test but employing a different initial gauge-length (provided multiple marks are present). This can be particularly advantageous in component testing, for example, when it is necessary to evaluate local strain at different locations, or in standard tensile tests when specimen necking has occurred outside the original initial gauge-length.

The recalculated strain can naturally be synchronized retrospectively with the other measured values via the testXpert testing software.

Strain distribution

The Strain Distribution option enables determination of local strains at multiple measuring locations along the specimen gauge-length. These are available as channels in testXpert. Up to 16 measuring locations are automatically recognized and evaluated during the test. This option also allows automatic real-time symmetrical adjustment of the initial gauge-length around the necking (to ISO 6892-1, Annex I).

Video Capturing

Video capture is a recording of the test (without retrospective recalcualation). The recording is synchronized with the measured curve, enabling the test to be viewed retrospectively. The option includes no hardware, as recording and synchronization take place entirely via the videoXtens system.

2D dot matrix

This option allows two-dimensional measurement of dots applied to a planar specimen surface. This enables determination of local strains and specimen inhomogeneities under load. X and Y co-ordinates plus the distances between dots are available as measured values.

Up to 100 measurement dots can be measured in any desired arrangement or in matrix form. Display in testXpert III is limited to 15 channels.

This option uses only one camera for measurement; any other cameras present are switched off beforehand.

Second measurement axis option 

This option allows biaxial measurement; transverse strain (e.g. change in width) can be recorded at the same time as longitudinal strain. Alternatively, change in width can naturally be measured alone.

  • Two versions are available for measurement of transverse strain:
  • measurement directly on the specimen edge with no additional markings (required for determination of r-value); a backlight is required for this version
  • measurement on the specimen surface using dot markings or sprayed-on pattern; with this version specimen illumination is via incident light.

Deflection measurement 

videoXtens can also be used for flexure tests. There are several options for measuring specimen deflection, depending on the type of test and the specimen condition and properties:

  • measurement using incident light via marks on the specimen
  • measurement using backlight on the specimen lower edge
  • measurement of deflection in the test axis or of the polynomial approximation of the curve.

Maximum deflection that can be measured: with videoXtens the maximum deflection corresponds to the FOV; with videoXtens Array to 1/3 of the total FOV (deflection is measured with one camera only in this case).
