lightXtens®

This optical extensometer is ideal for providing reliable, accurate measurements in tensile tests on highly ductile, highly elastic and touch-sensitive materials such as elastomers and latex plus all types of foil.

Advantages of the lightXtens^®

• It is suitable for all specimens that exhibit high fracture energy and whiplash at break and are therefore liable to damage mechanical, contact-measuring systems. This is often the case with belts, ropes and steel litz wire, for example.
• It provides accurate, non-contact strain measurement, even over extended temperature ranges in temperature chambers.
• lightXtens’ robustness in test conditions and ease of operation make it an attractive alternative to video or laser-based respectively contact extensometers.
• Connection to testControl electronics via a digital bus system, with synchronized force-travel measurement.
• Automatic and secure gage mark recognition.
• Initial gage length is measured at pre-load automatically during the test and transmitted to testXpert^®II.
• Wear-free, low-maintenance operation.
