The IMETRUM Video Gauge measures strain and displacement on materials, components and structures.

It is a non-contact, video based instrument with applications in material testing, component testing and structural monitoring.

The Video Gauge is frequently used to overcome challenging measurement problems such as high temperature or high-speed material testing.

For straightforward tasks such as batch testing of material properties it offers significant time and cost savings over traditional methods.

Case Study

Measuring changes in wing shape in a wind tunnel

Measuring changes in wing shape in a wind tunnel

The problem

Tests on a compliant wing that changed shape depending on the air flow over it required that the changes in shape be determined as the wind tunnel testing progressed. The changes had to be measured without influencing the air flow. At the same time the strains within the special core material that supported the wing skins had to be measured to check that it was behaving in the expected way (negative Poisson's ratio).
