These extensometers are designed for testing a wide range of materials, including metals, plastics, composite
All will work in both tension and compression. The dual flexure design makes them very rugged and insanitation which permits higher frequency operation.
They come standard with Epsilon’s quick attach kit, making it possible to mount the extensometer on the tension quickly and easily with one hand. The quick attach kit can be removed, allowing mounting of the extensometer or rubber bands.
The Model 3542 extensometers are strain gaged devices, making them compatible with any electronics design transducers. Most often they are connected to a test machine controller. The signal conditioning election extensometer is typically included with the test machine controller or may often be added. In this case the shipped with the proper connector and wiring to plug directly into the electronics. For systems lacking the electronics, Epsilon can provide a variety of solutions, allowing the extensometer output to be connected to boards, chart recorders or other equipment.
For gauge lengths 100 mm (4 inches) or greater see Model 3542L.
Features:
• May be left on through specimen failure.
• Full bridge, 350 ohm strain gaged design for compatibility with nearly any test system.
• All models can measure in both tension and compression and can be used for cyclic testing.
• Mechanical overtravel stops in both directions.
• Cable stops are used for overtravel protection where required. Epsilon’s cable stops are contained fully between the
extensometer, and do not hang below where they can interfere with fixturing-especially during compression testing.
• Standard units meet ASTM class B-1 requirements for accuracy. A test certificate is included. ISO 9513 class 0,5 te
available upon request.
• Hardened tool steel knife edges are easily replaced. A spare set comes with every extensometer.
• High and low temperature options extend operation from as low as -265 °C (-450 °F) to +200 °C (400 °F).
•Includes high quality foam lined case.
•Replaceable arms and spacers for ease of repair. This also allows changing the gauge length for different test requi
•Rugged, dual flexure design for strength and improved performance. Much stronger than single flexure designs, this
cyclic testing at higher frequencies.
•Standard quick attach kit allows one hand mounting to specimens
