Shown here is a small sampling of the custom and modified extensometers Epsilon has made. Sometimes the test requires a completely custom design. Often, though, special test needs can be accommodated by modifications to existing standard models. If you have special requirements and do not see it in our catalog, please contact us to discuss your application.
3561 Biaxial
Custom biaxial extensometer for plane strain measurement in sheet metal testing. This unique design contacts the test sample from one side only, as needed for a very wide sample. Used for formability testing.
3561 High Temperature Biaxial
Special high temperature biaxial extensometer for cruciform test samples at 1200 °C (induction heated). This extensometer uses ceramic rods and is capable of measuring very small strains.
Bulge Test
Special biaxial extensometer for limiting dome height bulge tester for sheet metal formability testing. Simultaneous X and Y strain measurements are taken.
Fretting Fatigue Slip Sensor
Custom sensor for fretting fatigue test system. Measures very small fret slip amplitudes at frequencies up to 60 Hz. Capacitive sensor with full scale displacement of 100 microns.
High Temperature Bend Extensometer
High temperature bend fixture and 3 point bend deflection sensor for bend tests up to 1000 °C. Capacitive sensor allows very small full scale measurement of 100 microns. Includes radiant furnace, fixtures and controlled atmosphere chamber.
