Self-supporting on the specimen

3575AVG model on sheet metal sample. 1 Short term use to 200 Ëš C (400 Ëš F) acceptable. •

Measuring range of 0.075 inches or 2 mm (specify).

This extensometer is self-supporting on the sample. It hasrounded 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 mmgage length Model 3542 extensometer, which measures the axial strain.The Model 3575AVG extensometers are strain gageddevices, 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.

Example: 3575AVG-LT: 2 mm measuring range, lowtemperature option (-265 °C to 100 °C) •

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.
