Diameter and ovality measurement instrument
ur LDS was developed more than 30 years ago to measure fine wires and it is still unique on the market due to its outstanding performance. It is widely used in laboratories (one axis version) as in-line applications (dual axes version). It has undrgone continuous evolution to adapt to the most recent technologies. It uses diffraction technology to insure high accuracy measurement (less than 1 µm) and very good repeatability compared to the shadow technology commonly used. This optical measurement is independent of wire position and vibration. Compact and robust, it includes all electronic and software in one packege for measurement autonomy.
How does one measure ovality ?
To calculate ovality, the diameter must be measured in several directions all around the wire. To avoid rotating the wire, or sensor rotation around the wire, CERSA developed a specific tool for laboratory application to keep the wire sample straight and taut. A crank and gear system provides for rotation of this sample in the LDS measuring laser beam. Fitted with this accessory, called WSR, it becomes a complete solution for measuring wire and cable up to 450 µm over 360°. After one turn, several types of data are displayed on the built-in screen or on your comuter : average diameter, min and max diameter, ovality (in µm or in % of the diameter). All of these values can then be recorded, printed or used for statistical analysis.
Other tools to support ovality measurement
CERSA also provides several accessoires for laboratory usage. If you want something easier to use than WSR, a foot pedal is available to trigger measurements one by one by turning the sample by hand. A label printer is also available to print different sizes of labels using customized templates to be affixed on spools. We suggest using our CIM Lab PC software designed specifically for such laboratory applications. Many features help you to connect all devices, display, sort, record and print measurement values. The licensed version provides extended features like user login management, customized groups by free fields or statistical analysis of your samples. In other words, CERSA provides a global solution to enhance laboratory efficency.
The laboratory version of our LDS is used worldwide in many sectors of the fine wire industries, and has been for years. Some examples of what it is used for are : steel, copper, bond wire, precious wires, carbon fiber, etc.
