Two High-Percision Materials Testers from Lloyd Instruments

Lloyd Instruments LS5 single column machine
AMETEK Test & Calibration Instruments has introduced the latest additions to its Lloyd Instrument line of advanced materials testing systems: the Lloyd Instruments LS5 and LS2.5. Both single-column machines feature the latest linear guide technology, pre-loaded ball screws and advanced software compensation systems, ensuring the highest level of precision displacement measurement.

The LS5 is a 5kN/1124 lbf machine; the LS2.5 is a 2.5kN/562 lbf device. Both are available with an extensive range of grips, fixtures, extensometers and software options and feature a large work area with 150 mm throat depth for larger specimens and a wide range of work tables for increased flexibility. Both are equally suited for a wide range of materials testing applications in quality control, academic, and research and development environments.

Among the industry applications for the LS5 are plastics, packaging, medical devices, automotive, electronics, textiles, rubber and pharmaceuticals. The LS2.5 system is especially suited for plastic, rubber and other high-elongation materials due to its wide crosshead travel, up to 1400mm. Both can be used for tensile and compression testing, friction, tearing, peeling, insertion/extraction, creep/relaxation and many other measurements in manufacturing, product development and research.

Each instrument offers a wide speed range for high precision accuracy and improved productivity. The LS5 has a crosshead speed range of 0.01 to 1016 mm/min, while the LS2.5 features a crosshead speed range of 0.01 to 2032 mm/min. Both machines have exceptional load accuracy of +/- 0.5 down to 1% of load cell value, which provides high dynamic range and thereby reduces the number of load cells required to cover the force range.

The machines use plug ‘n’play YLC Series load cells that feature anti-rotation collars to avoid load train twist and facilitate easy axial alignment. Eight interchangeable YLC load cells are available with different load ratings and resolutions.

At the heart of the LS5 and LS2.5 materials testing system is the user friendly, highly flexible and intuitive NEXYGENPlus materials testing software that allows users to control and monitor all aspects of the system from a single front end, ensuring fast, reliable and powerful testing and data analysis.

The software features a large built-in library of test methods that meet international test standards and SPC functionality for continuous monitoring of process parameters such as Cp and Cpk. In addition, it offers versatile data export facility and Window® software compatibility for seamless data transfer and video and still capture for visual analysis.
