Diamond SA
OTDR measuring devices are used in various ways in fibre optic technology. They enable extensive characterisation of existing fibre optic cabling networks. The use of launch and receive fibres is advantageous when it comes to ensuring precise results evaluations. With bidirectional backscatter measurements with launch and receive fibres, the attenuation values of the first and last plug-in connection can be determined precisely by averaging and device dead zones can be avoided. Measuring device manufacturers recommend different lengths of launch and receives fibres to avoid “phantom reflections”. These launch and receive fibres are also subject to measuring equipment monitoring and should regularly undergo revision in accordance with the OTDR measuring devices. A good measurement result depends on the state and quality of the measuring equipment used. Diamond offers various types of launch and receive fibres, one with standard telecommunications connectors and the other with an outdoor connector for harsh environments.

Marposs S.p.A.
Marposs complements its geometric measurement solutions with solutions for non-destructive testing using eddy current technology.The testing options can be divided in three large groups:Material integrity test, to check for the presence of defects (cracks, porosity, blow holes, inclusions) on the surface and in the layer just below the surface.Material properties test, to check if the thermal cycles (hardening, hardening and tempering, annealing, stress relieving, etc.) have been performed correctly. Material identification checks are done to sort parts with the same geometry but made with different materials.Thread inspection to check if the treading has been carried out and its quality.In addition to the non-destructive checks performed with the eddy currents, we have developed a durometer for the conventional measurement of surface hardness, according to the Rockwell scale (HRC or HRA); which uses a diamond penetrator to measure the hardness of the sample being tested.

NovoTest
The UCI hardness measuring method complies to ASTM A1038.The ultrasonic contact impedance (UCI) probe is purposed to be used for hardness measuring in the case of the testing area minimal thickness (from 1 mm), objects of complex surface shape, and for measuring surface hardened layers hardness.This method is very fast and easy: place the probe on the tested object surface, press the probe with the required effort to the surface and save the hardness value, shown on the display of the device. Small size diamond indenter allows measuring hardness value of all items, which are thicker than 1 mm. The UCI method of hardness testing is the least destructive because the hardness tester NOVOTEST T-UD3 with UCI probe leaves much smaller prints (imprints) than the majority of bench hardness tester would. That’s why a portable hardness tester with UCI probe is the best choice.
