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

Measurement of the consolidation and shrinkage processes in composites manufacture

The problem

It is very important in controlling the processing of advanced composites to develop an understanding of the consolidation and resin shrinkage processes throughout the cure cycle. For typical aerospace epoxies this requires the application of pressure up to a few Bar and temperatures up to about 180°C to a prescribed cycle. Equipment is available to do this such as Thermo Mechanical Analysers (TMA), but their sample sizes are very small and interpreting their outputs can be problematical.
