Epsilon MODEL 3542L Long Gauge Length Extensometers

Epsilon's Model 3542L extensometer is used for long gage length applications that involve low level strain measurements. With a gauge length over 50mm, this device is suitable for tensile and compression testing.

The dual flexure design provides the Model 3542L rigidity and insensitivity to vibrations. The extensometers can be used for testing a wide variety of samples including ceramics, composites, plastics, and metals. For larger measuring ranges and long gauge lengths, the model 3543 is usually employed.

The Model 3542L extensometers are provided with Epsilon's quick attach kit that facilitates easy mounting of the device on the specimen. Upon the removal of the quick attach kit, the extensometer can be mounted with rubber bands or springs.

These extensometers are strain gaged devices that can be used with any type of electronics employed in strain gaged transducers. They are often linked to a test machine controller with signal conditioning electronics.

A suitable connector and wiring is used to directly connect the extensometer to the electronics. Epsilon can provide different solutions for systems without the desired electronics. This allows the extensometer output to be connected to chart recorders, data acquisition boards, or other devices.
