Model EAH - High Elongation

For Testing Plastics, Rubber, and Elastomers

 

 

Description

Our model EAH high elongation axial extensometer is designed for the very long measuring ranges found in testing plastics, rubber and elastomers. Designed to minimize any influence on the test specimen while testing to specimen failure this model remains stationary during the test and only the small and light weight traveling heads move with the specimen as it elongates.

Unlike most of our extensometers, Model EAH utilizes a set of high performance, hybrid potentiometers to complete a full bridge configuration. As such, the output of this model can be made to output a high level signal (2 to 5 VDC) or mimic a strain gaged transducer (2 to 4 mV/V).

When configured for low level output, model EAH is compatible with most test systems and signal conditioning electronics designed for strain gage based transducers.

If configured with a high level output, model EAH can be directly connected to a data acquisition board (DAQ), chart recorder or other test equipment.

Features
  • May be left on through specimen failure.
  • Can be configured for use with most any test system or data acquisition boards / chart recorders.
  • May be used for testing to ASTM D412 standards.
  • Shipped with a fine-adjustment, magnetic base for easy mounting and adjustment.
Options
  • Connectors to interface to nearly any brand of test equipment.
  • Gauge length adapter kits.
  • Stand alone signal conditioners for use with DAQ boards.
