SEMI-AUTOMATIC STRENGTH TESTERS Tenso-Lab brand is one of the most widespread and flexible Universal Tensile Strength Testers worldwide. ■ Different types available (single and dual column, with different capacity) to suit the most exigent requirements: - for a variety of testing (tensile strength, elongation, tear, seam slippage, compression, puncture, etc.) - in different industries (textiles, non-wovens, cardboard, leather, plastics, etc.) - for various materials (fibres, yarns, tapes, fabrics, garment accessories, felts, cords/twines, ropes, etc.) ■ very strong structure, built according to CRE (Constant Rate of Extension) testing principle ■ versatile, interchangeable load cells & clamps/jaws ■ standard compliance, conforms to major testing methods (ISO, ASTM, JIS, BS, WOOLMARK, NEXT, M&S, etc.) ■ easy to operate, the software includes a wide choice of ready-made testing routines; they can also be created by the end user (no special skills are needed) ■ wide range of load cells, clamps, jaws/grips and tools ■ made in Italy and designed to meet the highest testing standards

Single Column Strength testers, up to 5 kN capacity, code 2512E, 2512F Tenso-Lab 4 series is the latest generation of the well-known Tenso-Lab semi-automatic tensile testers. The new models are distinguished by: ·· New hardware: high sensibility and robustness (can be used to test fibers (single and bundle), single yarns, hanks/LEA, fabrics and garment accessories), direct-drive ball bearing screw, low speed operation available, extended capacity to 5000 N, … ·· New components: improved load cells performances (higher accuracy level and new capacity load cell added), quick load cell & clamps/jaws...

Software The control software of our Strength Testers, available in several languages, has been designed, and constantly updated, in close co-operation with the most important textile laboratories and end users. ·· Easy to use ·· Highly efficient ·· Open towards the most common software applications ·· Designed in compliance with the most relevant quality and safety manufacturing Standards The operator can perform tests by selecting one of the available routines, or by manually entering all the testing parameters in the generic routines. Traction, compression, tearing, delamination, adhesion,...

Work Area The “work area” or “work done to break” data are mainly used for weaving yarns. If we have two yarns with the same breaking strength, but one stretches more than the other, the actual performance of the former on a weaving loom will surely be better, compared to the latter yarn with less elongation. This superior yarn performance can be measured in both terms of quality and efficiency. For experienced weavers it is therefore fundamental to know this parameter, which in practice is represented by the area below the curve (up to the maximum peak force). Elongation at Break The strength...

Example of Fabric Traction test Load Cells Available load cells: The choice of the load cell and clamps is of the utmost importance for a correct performance of the test according to the strength of the samples and to the testing method to accomplish. Load cells are interchangeable and can be replaced in a fast and easy way (in a couple of minutes), since they need to be calibrated only the first time before testing; then they are automatically identified by the Strength Tester at the subsequent changes. Main features: ■ high quality (manufactured by HBM); ■ dual accuracy range. Load cells are...
