This extensometer is self-supporting on the sample. It has rounded contact edges which measure the sample at two locations. As the test sample is pulled, the contact edges follow the part of the sample they were mounted on, measuring lateral strain on the sample at the same location throughout the test. The extensometer has a single output, which is the average of the two lateral measurements.

These extensometers are used with a 2 inch or 50 mm gage length Model 3542 extensometer, which measures the axial strain.

The Model 3575AVG extensometers are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers. Most often they are connected to a test machine controller. The signal conditioning electronics for the extensometer is typically included with the test machine controller or may often be added. In this case the extensometer is shipped with the proper connector and wiring to plug directly into the electronics. For systems lacking the required electronics, Epsilon can provide a variety of solutions, allowing the extensometer output to be connected to data acquisition boards, chart recorders or other equipment.

• May be left on through specimen failure.
• Full bridge, 350 ohm strain gaged design for compatibility with nearly any test system.
• All standard units meet existing ASTM class B-1 and ISO 9513, class 0,5 requirements for accuracy.
• Includes high quality foam lined case and spare set of tool steel knife edges.
• Rugged, dual flexure design for strength and improved performance. Much stronger than single flexure designs.
• Self-supporting on the specimen
• Measuring range of 0.075 inches or 2 mm (specify).
• Single clip-on unit directly measures lateral strain as an average of two locations.
• Greatly speeds up testing and allows digital data collection as compared to manual measurements.
