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. Integrated safety mechanism protects the sensor arms on specimen break.

Advantages and features

  • Can be used up to specimen break, even with high loads and brittle specimen material.
  • Maximum precision even with large measurement travel (up to 700 mm) and in 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 satisfying the additional requirement in ISO 527-1 (2011)
  • multiXtens is already calibrated from a measurement travel of 20 µm in Class 0.5
  • The low drag force and ability to adjust the contact pressure of the sensor arms as required means enables reliable, traceable testing of sensitive specimens.
  • Deformation of the specimen is recorded in the elastic and plastic deformation ranges throughout the entire test.
  • multiXtens is suitable for cyclic tests.
  • Compression and flexure tests can be performed by simply changing the sensor arms.
  • Tilting 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 Young's modulus and determination of r and n-values, and Poisson's ratio
  • The sensor arms can be changed without tools and are automatically recognized by multiXtens.
  • Operation with temperature chambers is possible using suitable sensor arms.
  • Fully automated system:
    - measurement of free space between specimen grips
    - centering of multiXtens measurement carriages
    - automatic attachment and removal of sensor arms
    - automatic gauge-length setting.
  • 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.
