....Model 3575AVG Sheet
Metal r-Value Extensometer ....
for measuring r-value in sheet metal testing, this extensometer
averages the lateral strain at two locations. This is
used simultaneously with a Model 3542 for axial strain
measurement. Also used whenever it is desirable to have
two lateral strain readings which are averaged.
This extensometer is self-supporting on the sample.
In operation, 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, to measure lateral strain on the same
material. The output is an average of the two lateral
measurements, combining the readings into a single averaged
output. Unlike other designs, Epsilonís contacts move
with the specimen, so the readings are always on the
original part of the test sample they were mounted to.
These extensometers are used with a 2 inch or 50 mm
gage length Model 3542 extensometer, which measures
the axial strain.
