| At the DKT Fair Zwick will be presenting one of its flagship products. A universal testing machine will be equipped with the worlds most advanced digital extensometer and configured for tensile tests on elastomers.
Zwick believes that its multiXtens extensometer is the only device available which is capable of measuring modulus of elasticity with a resolution of less than 0.1µm, and elongation to failure with a measuring range of 700mm (minus the initial gauge length). In order to speed up testing on different specimen geometries the gauge length can be automatically set to the required value or as a function of the specimen cross-sectional area.
A unique and innovative ‘plug and play’ sensor arm system enables the multiXtens to be used for most tensile, compression and cyclic tests – even those carried out inside a temperature chamber. Compression and flexure tests previously requiring the use of analogue measuring transducers can be carried out simply by interchanging the sensor arms, and the system recognises and adapts to the change of configuration immediately without requiring any operator intervention.
The multiXtens is perfectly suited for research, education, and commercial testing laboratories where test requirements are constantly changing. With today’s conventional testing machines it is often necessary to use more than one extensometer, but with its digital technology, high accuracy, flexibility and ease of use, the multiXtens reduces the set-up time, maintenance, and re-calibration costs associated with such testing.
Typical applications for the deployment of the multiXtens are tensile, compression, and flexure tests on plastics, metals, composites, and other materials where small displacements, modulus determination and high elongation is to be measured. For even more demanding tests requiring transverse strain measurements such as r value determination on metals or Poisson ratio, the multiXtens can be equipped with an automatic transverse strain extensometer. This device can be attached automatically at the start of the tensile test and removed before specimen fracture enabling the multiXtens to be used in robotic testing applications and deliver additional benefits in cases where the manual handling of specimens affects the integrity of the test results.
MultiXtens complies with class 0.5 of EN ISO 9513 over its entire measuring range, and as with most Zwick’s products its operation is totally integrated into the proprietary software, testXpert® II. Laboratories with many different test requirements will appreciate the vast library of standard tests as well as the capability to build complex and non-standard test procedures.
Zwick’s global and more than 20 years of experience in automated materials testing allows testXpert® II to be integrated into company IT systems and this improves data integrity and traceable quality audit trails. Efficiency is increased through faster product release and reporting. |
