Testing & measuring

In-line measuring CERSA-MCI has developed a common technology and software environment for a line of optronic measurement instruments for wires and cables. Laser Sensor (LS) uses only static components, and has no moving parts. The range was originally designed for production lines, as single units or in a network, and is widely used in laboratories.

The instruments provide realistic in-line measurements and statistics without averaging. The standard refe- rence wires come from different highly specialised laboratories in different countries, to provide a recognised international metrological reference. Features of the range include: Handling of diameters from 5µm to 2,000µm, • 1 or 2 axes Repeatability within 0.03% of the diameter limited • to ±0.01µm Temperature compensation from 10˚C to 40°C • (50 to 104°F) Capability to evaluate surface quality or roughness • The following options are available: Wire sample rotation (WSR) at constant tension • Oscillating support (OS) for in-line ovality • measurement Battery power for portability • Set of four reference wires for calibration and ISO • certification: 30 to 2,000 microns ±0.1µm

Tensile testing

Creating the ‘Dogbone’ sample test piece used for tensile testing can be the point that slows testing procedures and creates a backlog.

In the past, the common practice has been to mill these samples. The difficulty with milling is that it is a slow process and can become a bottleneck in the testing process. A lapse of days between material production and testing can result in material being shipped before the testing is completed. With the Vale sample press a sample can be quickly, easily, and accurately created for testing so that tensile and elongation tests can be completed in good time by the metallurgical laboratory. Tensile test sample (dogbone) presses can be used to quickly stamp accurate samples, from the thinnest material up to 12.5mm thick, and the presses can be designed to punch either the small 10" samples or the larger 20" samples.
