You can get acquainted with models of extensometers of various types, as well as unique equipment for testing (fixation, installation of samples for exposure to certain load parameters) on the website of the Metrotest company.

Contact and optical non-contact video extensometers

Technical information about any type of material that is used for the manufacture of parts undergoing certain types of physical stress should contain the results of its laboratory tests for:

  • Stretching in the longitudinal and transverse directions.
  • Compression with specific parameters affecting the sample.
  • Bending and twisting.

Devices for measuring the magnitude of the resulting deformation are extensometer https://metrotest.ru - catalog of the supplier of this category of testing equipment of the Metrotest company. They are divided into 2 main types according to the principle of their application in practice.

Contact extensometer

This type of test device is simple in design. The device is fixed on the sample before starting to test it using the effects of various types of physical activity. This allows measurements:

  • In various configurations of deformation occurrence.
  • With parameters from 1 to 100 mm.

Modern developments of contact devices are equipped with their own guides, which eliminates the impact on the test sample and takes measurements with guaranteed accuracy class 1 and 0.5 according to the international standard ISO 9513.

Non-contact video extensometers

Modern technologies for creating complex electronic, radiotelemetric or equipment (units, parts), experiencing colossal physical exertion, while in the following conditions:

  • High or low temperatures, as well as their sudden changes.
  • In a vacuum or active gas environment.

Require testing of materials or finished products in a similar environment using special cameras. For such measurement of deformation changes, non-contact optical video extensometers are used. Also, this type of equipment is indispensable when testing super thin or particularly fragile samples.

You can familiarize yourself with models of extensometers of various types, as well as unique equipment for testing (fixation, installation of samples for exposure to certain load parameters) on the website of the Metrotest company. The resource provides for the possibility of consulting interested clients in an online format without prior registration.
