Model 3442 Miniature Extensometers - 33099 3442
Miniature Extensometers Epsilon
Technology CorpVery small and rugged,yet ultra-light weight,these units are widely used for testing small and delicate samples.Ideal for many biomedical tests,as well as for wire and thin sheet materials.Also great for low cycle fatigue testing where short samples are used.

High and low temperature options extend operation from as low as -265 °C (-450 °F) to +175 °C (350 °F).
-010M 10.0 mmWeighing as little as 8 grams, these tiny extensometers alsohave very low operating force, resulting in low specimen contact force and influence. All use an Epsilon proprietary dual flexure design, which makes them very rugged for their size. Most are only 0.6 inches tall (15.25 mm).These exten- someters will fit in the small space between grips, which usually results when small test samples are used.The Model 3442 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 systemslacking 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.

•Replaceable arms and spacers for ease of repair. This also allows changing the gage length for different test requirements. Model Number 3442-________-______-____

•Rugged, dual flexure design for strength and improved performance. Much stronger than single flexure designs, this also allows cyclic testing at higher frequencies.
