  • (1888PressRelease) October 01, 2015 - As the demands grow for more fuel efficient power plants, engines and lighter weight vehicles, materials scientists and mechanical engineers are seeking to develop new ceramics, alloys and structures that can operate safely at higher and higher temperatures. Understanding how these innovative materials perform is not easy, with most sensors being highly sensitive to temperature, and unable to operate effectively at 1000 degrees.

    Because of these twin demands, Imetrum is finding interest in its non-contact, high precision measurement systems hotting up. Both the UVX flexi Video Extensometer and the 3D displacement measurement systems provide the perfect solution for companies needing to test material properties and component deformation in extreme temperatures. By being able to set up at a distance while the specimen under test is inside an environmental chamber, measurements can be taken through the chamber window. This method has proved to be superior to conventional techniques that can be cumbersome to set up and not always accurate, even past the point at which the material becomes red hot.

    Recent customers of Imetrum systems for high temperature measurement include world-leading UK based universities and American and Asian aerospace research institutions. Applications include mechanical investigations of nickel superalloys for turbine fan components, tensile testing of carbon composites for aerospace structures and deformation of fuel cell stacks in operation. By using carefully selected optical components and high precision, robust tracking algorithms, strains and displacements have been recorded that were not previously possible to obtain, providing valuable information to refine designs and validate finite element models.

    Used extensively to measure strain, displacement, rotation plus other important parameters in materials while under test, Imetrum's systems comprise digital cameras coupled to a powerful controller and Video GaugeTM software, enabling virtual targets to be tracked in real time and output a host of different measurement options. The beauty of this non-contact system is that users simply define points of interest in a captured video and using the pattern on the item being tested will be able to make measurements. The measurements can then be stored locally, fed into other test machines, or transferred to a data logger. When testing rare and or delicate specimens at extreme temperatures, the benefit of being able to post-process recorded images to add new measurements saves valuable resources even when specimens have been destroyed. All-in-all, the combination of time-saving, cost-saving and increased level of information means that Imetrum only expect the take-up of their products to grow as the drive for a cleaner environment continues apace.

    Imetrum's product now has over 300 users worldwide and is a versatile, non-contact video based system that allows the user to test a variety of important parameters (strain, rotation, displacement etc.) in real time, in a single test. The Video based measurement system is ideal for use in exacting market areas such as aerospace, automotive, defence, oil & gas, energy, R&D and high technology motorsport, where highly accurate measurements directly traceable to national standards are critical for their materials, component or sub-assembly development. In materials it is the world's first video extensometer capable of being calibrated to BS EN ISO9513 Class 0.2, which also equates to the equivalent American standard ASTM E83 Class B-1. As the Imetrum system is video based, a record of the test can be saved so engineers can either post process the test or complete further analysis without the need for repeating the test, saving both time and money.
