The highly versatile extensometer for changing applications

The multiXtens II HP extensometer is a highly versatile extensometer for changing applications with very easy operation and little operator influence. It meets accuracy class 0.5 (ISO 9513) over the entire measurement range up to 700 mm. This allows for measurement of both small and large specimen extensions. Easily interchangeable sensor arms and adaptable transverse strain extensometers allow for a multitude of tests: tensile, compression and flexure tests, as well as cyclic tests on plastics, composites, elastomers, metals and composite materials, transverse strain measurement, fine strain measurement and tests in a temperature chamber.

Fully automated system: automatic test area measurement (tool separation), automatic centering of the sensor arms, automatic L0 setting, automatic attachment and detachment of the sensor arms.
Easy operation and minimized operator influence.
Traceability: self-identification of the measurement carriages and installed sensor arms—the system knows automatically which components are being used.
Robust extensometer, which can measure up to specimen break. An integrated safety mechanism protects the sensor arms at specimen break.

The multiXtens II HP

Advantages and features

Can be used up to specimen break, even with high loads and brittle specimen material.
Highest level of precision even when measurement displacement is high (up to 700 mm) and can be used with temperature chambers
Accuracy Class 0.5 to EN ISO 9513
Maximum error ±1 μm in the differential displacement measurement between two measurement points in the range of 20 μm to 200 μm, fully fulfilling the additional requirement stipulated by ISO 527-1 (2011)
multiXtens is already calibrated from a measurement travel of 20 µm in Class 0.5
The low drag force and the ability to adjust the contact force of the sensor arms as needed means you can test sensitive specimens reliably and with traceability
Deformation of the specimen is recorded in the elastic and plastic deformation range throughout the entire test
multiXtens is suitable for cyclic tests
Compression and flexure tests can be performed by simply changing the sensor arms
Tiltable knife edges prevent damage to the sensor arms and knife edges at specimen break.
A third measurement-carriage enables fully automatic fitting of transverse strain and fine strain extensometers to multiXtens. This is very important for accurate determination of Youngs Modulus and determination of r- and n-values, as well as Poisson's ratio
The sensor arms can be changes without tools and are automatically recognized by multiXtens.
Operation with temperature chambers possible using suitable sensor arms
Fully automated system:
– Measurement of the clearance between the specimen grips
– Centering of the multiXtens measurement carriages
– Automatic attachment and detachment of the sensor arms
– Automatic gauge length setting
The multiXtens is approved for closed loop strain rate control to ISO 6892-1 (2009) Method A (1) and to ASTM E8 – 09 Method B

Function description

The guide system has two integrated measurement carriages that can be moved independent of one another. Each measurement carriage has a complete measurement carriage drive and a microprocessor system, which records and prepares the status and measurement data of the measuring heads. Furthermore, it controls the measurement carriages/measuring head drives and monitors their safety limit values.

Even the transmission of measurement, control, and status signals between the measurement carriages, measuring heads, and central measurement and control unit is handled by the microprocessor system.

Transverse strain measurement

The choice is yours: from manual clip-on solutions and mechanical transverse strain extensometers to our videoXtens solutions:

Due to their simple operation and high reliability, the non-contact videoXtens transverse strain extensometers are increasingly becoming the option of choice.They also stand out with their accuracy class 0.5 (ISO 9513), high level of robustness and the evaluation options in the testing software.

The optical transverse strain extensometers videoXtens T-40 HP and videoXtens T-160 HP measure the change in width at the specimen edge without manual markings on the specimen thanks to the intelligent edge detection algorithm. Measurements can be taken at 1-10 measuring points and both the individual values and the average value are provided.

The videoXtens T-160 HP sets a new standard for r-value measurement: lower dispersion of the r-values, measurement over the entire gauge length in accordance with the recommendation of ISO 10113:2020 and other powerful functions have elevated it to this position.

videoXtens T-40 HP, optical transverse strain extensometer

The classic option among tactile transverse strain extensometers is the mechanical transverse strain extensometer, which measures via one, two or four measuring lines. It is mounted on the sensor arm extensometer and therefore does not apply weight on the specimen. It can be attached to and removed from the specimen either manually or fully automatically.

Alternatively, you can also use clip-on solutions for the change in width measurement.
