Model 100R Extensometer
The Tinius Olsen model 100R is a
high elongation extensometer that is
designed to measure the ‘stretch’ of
a wide range of materials including
elastomers and non-rigid plastics.
The initial measuring length, or gauge
length, can be changed to suit the
specimen size or the test standard
that is being applied.
The unique design ensures an
extremely low tracking force for testing
sensitive materials, as well a robust
construction that can easily withstand
the high release forces and breaking
energies with certain specimens. The
design also incorporates a simple yet
effective method with which the
extensometer followers are attached
to the specimen, allowing rapid
throughput of testing.
Extension is measured by
attaching two counterbalanced
extensometer clamps to the specimen
at a pre-selected gauge length. When
tensile forces are applied to the
specimen by the testing machine, the
slightest change in gauge length is
measured by an optical encoder.
Signals from the optical encoder are
fed into the signal conditioner
interface for processing.
The 100R extensometer can be
fitted to all sizes of screw driven
materials testing machines.
