Strain measurement systems

Reels and spools

Yangzhou Qunye Electrical Machinery Factory has developed and produced machine spools for cable and lines for over twenty years, selling both at home and across the world. The company’s main products include the PND series double line high speed spools, the PN series punching type machine spools, plastic spools and spool tools produced to conform with national and international standards, certificated by ISO 9001, 2000. Non-standard products are available to customer specification and design.

Efficient strain measurement systems from Zwick ▲ ▲

The non-contact measurement principle eliminates contact forces in the transverse direction, allowing thin and/ or sensitive specimens to be tested. TheMacrohigh-resolutionextensometer records strain in both elastic and plastic ranges during the entire tensile test up to specimen break. The system is designed to be easy to set up and operate, while high durability and low wear make it suitable for integration into robotic testing units. Zwick GmbH – Germany Fax : +49 7305 10200

By combining the videoXtens transverse strain extensometer with the Macro extensometer, Zwick has produced an optical/contact strain-measurement system for the metal and auto-motive industries. Both extensometers deliver extremely high accuracy within their class and provide excellent reliability. The optical measuring system can be used for specimens with very small gauge lengths (from 15mm). videoXtens’ non-contact, high-resolution measure- ment allows determination of r-values to ISO 10113 and requires no speci- men markings – a sophisticated edge identification algorithm is employed.
