Optical measurement system for compression testing
Unlike tensile tests grips, compression platens can often inhibit the access to a specimen. Unlike contacting methods though, the Video Gauge only requires a line of site to the specimen that requires measurements thereby removing past limitations. Large strains of rubbers or ductile metals can be monitored without any threat of damage from crushing between the platens, whilst testing through failure improves operator safety from having to reach in to remove contact devices.A range of gauge lengths from under 1mm to over 100mm is possible, allowing the specimen geometry to be designed independently of the extensometry device.
A 10VDC output can be generated from the video extensometer for integration with existing test machines and software strain channels.
Multiple point-to-point measurements can be made of axial and transverse strain allowing the Video Gauge to act as an averaging biaxial extensometer.
