Model 3543 Long Gage Length ExtensometerThis model is available in gage lengths from 2 inches (50 mm) and larger, with measuring ranges up to 4 inches (100 mm). It is a uniquely designed unit that may be left on through specimen failure. These extensometers are widely used where long samples are required. They are ideal for testing steel re-bar, weld joints, and wire materials. The unique pull-apart design protects the extensometer when the specimen fails. These are tension only units. During operation, the upper half of the extensometer pulls out of the main body. Tapered measuring beams activate strain gaged flexures within the unit. This unique design allows long measuring ranges, yet retains the compatibility with electronics for strain gaged transducers. These models offer high accuracy and are light weight but rugged, with low operating force. The units have hardened tool steel knife edges. Standard quick attach wires provided with the extensometer work on flat specimens up to 0.5 x 1.25 inch (12 x 31 mm) and on rounds up to 1 inch (25 mm) diameter. Optional quick attach kit wire forms are available for use on larger samples. See Model 3542L for long gage lengths with smaller measuring ranges. The Model 3543 extensometers are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers. Most often they are connected to a test machine controller. The signal conditioning electronics for the extensometer is typically included with the test machine controller or may often be added. In this case the extensometer is shipped with the proper connector and wiring to plug directly into the electronics. For systems lacking the required electronics, Epsilon can provide a variety of solutions, allowing the extensometer output to be connected to data acquisition boards, chart recorders or other equipment.
