lightXtens Extensometer

The lightXtens extensometer is ideal for safe, reliable, accurate measurements during tensile tests on high-extension, highly elastic and contact-sensitive materials.

  • Ideal for specimens displaying high fracture energy and prone to whipping at break and therefore likely to damage mechanical, contact-type measuring systems.
  • Its robustness and ease of operation make it an attractive alternative to video or laser-based extensometers.
  • Satisfies the requirements of Accuracy Class 1 to ISO 9513 from 3 mm.

Key Advantages and Features

Advantages and features

Non-contact, simple, fully automatic

The lightXtens extensometer features non-contact operation. It is extremely easy to operate and requires no special knowledge. There is no need to adjust or configure the lenses. The test sequence is completely automatic:

  • automatic determination of initial gauge-length, with transmission to testXpert testing software
  • reliable, automatic identification of gauge marks
  • tracking of gauge marks and transmission of all data to testXpert testing software
  • return to start position.

Specimens are marked beforehand with dots or strips made of a special film - various marking systems are available. Connection to the testControl II electronics is via a digital bus system, with synchronized force-displacement acquisition.

  

Robust, resistant, reliable

lightXtens is a robust and highly reliable system, even in harsh environments. It is resistant to external influences such as light variations, extraneous light and air currents. lightXtens is also wear-free in operation.

lightXtens is also suitable for use in an extended temperature range in conjunction with temperature chambers - no special set-up procedure is required for lightXtens.

Applications

lightXtens is a non-contact extensometer for standardized testing situations. It is extremely easy to operate, with a fully automatic test sequence.

  • Typical applications
  • Tensile tests on high-extension, highly elastic materials: rubber and elastomers (e.g. to ISO 37, ASTM D412, DIN 53504), natural rubber (latex), films (e.g. to ISO 527- 3, ASTM D882, ASTM D532), textiles (especially ropes, belts, industrial textiles).
  • Tensile tests on specimens with large initial gage-length, e.g. wire ropes, litz wire.
  • Specimens with high fracture energy and prone to whipping at break, which might damage mechanical, contact-type measuring systems.

Technical Overview

The lightXtens extensometer can be used with materials testing machines from the AllroundLine and ProLine series. 

  • lightXtens for mounting on an AllroundLine testing system
  • ProLine lightXtens for mounting on a ProLine testing system
