Video Gauge for Material
Testing
At home with materials from
composites to elastomers, Imetrum’s measurement systems have been proven
to give precision data for a range of demanding materials.
Types of Material Testing
- Multi-Point
Bend Testing
- Compression
Testing
- Shear
Testing
- Tensile
Testing
Multi-Point Bend Testing
The strain, displacement, extension or rotation between two points can be
monitored as with a traditional extensometer, allowing measurements to be
compared to historic data. Multiple points can be monitored for average
strain, checking for equal stress distributions or focusing on different
parts of a component.
Compression Testing
Unlike tensile tests grips, compression platens can often inhibit the
access to a specimen. Unlike contacting methods though, our systems only
require 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.
Shear Testing
Shear modulus measurements can be taken for V-notch or short beam
specimens of any size using the appropriate hardware, with minimal
preparation through a sprayed on speckle pattern. This enables tests to
be performed on micro specimens or full sized components.
Tensile
Testing
Though specialized algorithms and lenses, the system performs as a class
0.5 extensometer for strains under 1%, allowing accurate yield and
modulus measurements. Using tailored lenses this range can be extended
for strains up to 600%, allowing the priorities to be tuned for each
material.
Simple Test Frame
Interfacing
With the ability to output a 10VDC signal, our systems can give out
strain data to feed in to common system controls. Similarly, they can
read the digital outputs from the machines in order to log them alongside
the measurements.
Advantage:
- Certified Class 0.5
Accuracy
when tested from 0.1 to 1% strain. This ensures your pre-yield
measurements are accurate and repeatable.
- Zero Specimen
Interference
Past extensometry issues are avoided through the use of non-contact
method. Delicate films and 7μm fibres have been measured where previous
methods were too harsh, whilst the repeatability of larger specimens is
improved through the removal of contact slipping and stress
concentrations, along with the ability to test any sample through
failure.

Gauge Lengths of 100um to 1m
Material testing lenses can offer resolutions better than 5μє for small
gauge lengths, whilst the standard lenses offer resolutions of 20μє for
higher gauge length samples with extreme elongations.
