Video Extensometer with Independent Control
Non-contact extensometry is the method of choice for applications where it is particularly difficult to measure strain using traditional contacting means.
Because these extensometers don’t touch the specimen, they are ideal for:
♦ thin or fragile specimens where contacting alternatives introduce stress points that may cause premature breaks
♦ specimens that require high temperature or submerged environments
♦ situations where specimen failure is accompanied by a huge release of energy.
Features & Benefits
The advantages of this ‘external’ control software are that the data collected from the external control software can record data from multiple pairs of data points recognised on the specimen. Not only does the external software record what has happened in the strain measurements, but it also records the video of the whole test.
It is possible to rerun a series of tests using different test points on the specimen on a replay of the video, without the need for more specimens.
