These axial extensometers were created with the specific purpose of measuring axial strain in testing conditions with high temperatures without the use of external cooling.
For tension and fatigue testing applications at temperatures ranging from 40° to 540° C (100° to 1000°F), they offer stable output with little creep.
Extensometers track the extent of a material sample’s extension, compression, or shear deformation when force is applied in a testing device.
They are frequently used to gauge the strain of the test piece, which is determined by dividing the length change of the test specimen by its initial gauge length.
The Global High Frequency Axial Extensometer Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
High Frequency Axial extensometers by Epsilon, Model 3542, are multipurpose devices appropriate for compression, axial tensile, and cyclic testing.
Model specifications include gauge lengths of 0.5 to 2 inches and strain measuring ranges of 5% to 100%. (and 10 to 80mm).
These extensometers have been created to test a variety of materials, including composites, metals, ceramics, and polymers.
Both compression and tension are used by each of these devices. Due to their dual flexure construction, which allows for higher frequency operation, they are incredibly robust and vibration-insensitive.
The extensometer can be quickly mounted on the test specimen with just one hand thanks to an Epsilon quick attach kit that is included with the instrument.
Extensometer attachment with springs or rubber bands is feasible after removing the quick attach kit. Since these extensometers are strain gaged devices, any electronics created for strain gauge transducers can be used with them. They are generally attached to a controller for a test machine.
The test machine controller typically comes with the signal conditioning electronics for the extensometer, however it is optional. In this instance, the extensometer is provided with the correct cabling and connector for easy direct insertion into the electronics.
The extensometer output can be connected to chart recorders, data acquisition boards, or other equipment using a variety of methods provided by Epsilon. All types can measure in tension and compression and can be used for cyclic testing.
