Tensile extensometer 3800 series

long-strokefor large deformations

Designed for rubber, elastomer and high-elongation plastics testing for strains from 100%-2000%ε. Their unique design allows testing to failure and minimizes interaction with the sample. Epsilon extensometers are COMPATIBLE WITH VIRTUALLY EVERY BRAND OF TEST EQUIPMENT and can be supplied with the correct connector to plug in directly, or supplied with a separate conditioner and amplifier. WITH EPSILON’S 20+ YEAR HISTORY OF SERVICE to the materials testing community, you know we will be there to stand behind our products when your critical application requires it. 38 EXTENSOMETER MODELS are available in many thousands of variations. Our focus on helping customers has led to the development of models to cover nearly any test method. The main body of this unique extensometer remains stationary during testing, held in position by the adjustable magnetic base included. Only the very light, small traveling heads move as the sample elongates during a test. These attach to the sample with small spring clips. Each head pulls a cord out from the extensometer as the head moves. These models use low friction potentiometers and have a range of factory-selectable outputs. The extensometer is driven by an excitation voltage and has output proportional to the input. They are provided with outputs that mimic strain gaged devices (2-4 mV/V). The Model 3800 can be used with virtually any signal conditioning electronics designed for strain gaged sensors. For systems lacking the required electronics, Epsilon can provide a variety of solutions for signal conditioning.
