Model EAA - Averaging Axial Extensometer

For axial tensile, compression, and cyclic testing where an averaged output is desired.

Our model EAA - averaging axial extensometer is built around our new, monocoque module design. This innovative design provides a very stiff module body which results in improved performance and ruggedness over existing units. To keep our extensometers as light as possible, even the module cover is used as an integral stressed member. As an added bonus, our design in more compact and will more easily fit into the tight space of your environmental chamber. It is also lighter to reduce the influence of the extensometer's weight on the specimen under test.
Model EAA - Averaging Axial Extensometer

All model EAA extensometers feature a full, strain gauge bridge design and are compatible with most any brand test equipment. This model can be configured for a single, averaged axial strain signal or for two independent axial strain signals. We can install the proper connectors to interface to most any electronics including Instron, ADMET, and MTS. If your test frame or set-up does not have the required strain signal conditioner, we can supply stand-alone electronics calibrated with your extensometer. This will allow you to use a chart recorder, digital display, or data acquisition card.

All standard models meet ASTM B-1 and ISO 9513, class 0,5 accuracy requirements. Each extensometer comes with an inspection certificate traceable to NIST, a spare parts kit, a spare set of tool-steel knife edges, and a quality, foam lined, plastic case.

Standard models available in any combination of measuring range and temperature range listed below. If you need an extensometer in a configuration other than what is listed, please contact us with you specific needs.
