Extensometers - EXPlus Long Travel Contacting Extensometer - 1

EX250Plus and EX800Plus EX250Plus EX800Plus General Purpose Contacting Extensometers EXPlus general purpose contacting extensometers are designed for accurate strain and extension measurement of a wide range of materials such as semi-rigid plastics, elastomers, rubbers, wire, cable, textiles and more, up to a maximum sample thickness of 25 mm. Available in two travel lengths, the EXPlus extensomer can be fitted to any Lloyd Instruments EZ and Plus Series materials testing machine. ‘Plug & play’ technology makes it is easy to install and calibrate. The extensometer is designed with great flexibility of adjustment to ensure easy and precise attachment to the sample and best ergonomic test positioning. Two mounting platforms are available. The unit can be stand mounted on the test machine’s anchor pin at the base of the machine, enabling it to rotate from side to side for best possible access to the test area. In addition, the unit can slide horizontally towards and away from the sample as well as having vertical adjustment to allow for different sized grips and samples to be fitted. Alternatively, the unit can be mounted at the side of the test machine. For added flexibility, the extensometer arms can be locked open to simplify attachment to the sample. The two models, EX250Plus and EX800Plus, provide travel up to 250 mm and 800 mm respectively. Features • Meets BS EN ISO 9513 : 2002 • Rugged construction allows specimens to be tested through failure • Rubber buffers absorb impact loads at sample break to safeguard extensometer arms • Two travel lengths available depending on elongation of sample under test • One cable connection to material test machine - no extra electronics required • Suitable for tension and compression testing • Vertical, horizontal and rotational extensometer position movement for easy access and attachment to sample (depending on mounting platform used) • Low friction bearings and lightweight arms minimise inertia allowing sample movement to be instantly transferred • Uses ‘plug & play’ technology - once plugged into the test machine, the extensometer is ready for testing • Straight and round knife blades supplied as standard for attachment to different types of samples Specifications Measurement Principle: Accuracy: Maximum Clamp Opening: Maximum Elongation: Variable Gauge Lengths: Speed Range to Follow: Temperature Range: Resolution: Maximum Activation Force: Net Weight: EX250Plus extensometer: EX800Plus extensometer: Optical encoders 0.5% of reading In full accordance with ISO 9513:2002 25 x 25 mm (standard) (0.98 x 0.98 in) 250 mm or 800 mm between arms (depending on model used) 10 - 100 mm gauge setting with accuracy of 1% 1.0 - 1200 mm/min 5ºC to 35ºC operating ambient 1.25 microns <0.2 N - static and dynamic 6.5 kg (stand weight 5.0 kg) Total 11.5 kg 10.0 kg (stand weight 5.5 kg) Total 15.5 kg Specification Sheet January 2006 January 2006 SS-MT-6640-0106 SS-MT-6640-0106 © 2006, by AMETEK, Inc. © 2006, by AMETEK, Inc.
