Model EAGM - Miniature Axial

For Tensile, Compressive, and Cyclic Tests

 

 

Description

Our model EAGM miniature axial extensometer is basically a smaller version of our standard axial model EAG.  It is also designed around our innovative, cross-flexure module. This extensometer is designed for improved performance and ruggedness. It also features a side-exit cable to reduce cable wear / damage.

Model EAGM also features our unique, ultra-low profile, axial Quick Attach System allowing easy, one-handed, specimen attachment even between very close grips. This attachment system is designed to provide easy attachment while not influencing the extensometer's output or performance. The wire forms on our system are designed to transmit the attachment force axially through the extensometer body.

The Quick Attach System includes round and flat wire forms for both round and flat specimens. If you prefer to attach the extensometer with springs or rubber bands, spring mounts are available.

 

Features
  • May be left on through specimen failure.
  • 350 ohm, full bridge strain gaged design to ensure compatibility with most any test system.
  • Designed to measure in both tension and compression and can be used for cyclic testing.
  • Built-in mechanical over-travel stops provide protection in both directions.
  • Low profile Quick Attach System allows one hand mounting to specimens in tight spaces.
  • Standard units meet ASTM class B-1 requirements for accuracy and a verification certificate is included with each unit.
  • Rugged, optimized, dual flexure design for strength and improved performance.
  • Low friction cable stop design does not influence performance.
  • Replaceable, tool steel knife edges and all units are shipped with a spare set.
  • Solid, replaceable arms are not easily damaged like other designs.
  • High and low temperature options extend operation range from -270°C to +200 °C (-454 °F to +400 °F).
Options
  • Connectors to interface to nearly any brand of test equipment.
  • Custom wire-forms available for attachment to large specimens.
  • Gauge length adapter kits.
  • Stand alone signal conditioners for use with DAQ boards.
  • High-Toughness, and specialty knife edges.

Nearly 10 Year History of Service

we will be there with service and support when you need it

 

Our model EAGM miniature axial extensometer is built with a modular design. This allows us to supply the exact gauge length, measuring range, and temperature range required for your test. For compression testing of composites, such as ASTM D695, model EAGM extensometers can be configured to directly mount onto compression fixtures. Please contact us if your particular configuration is not listed.
