Diameter measuring tools and defect detection

IN-LINE

C ERSA has developed a line of instruments that uses various technologies to cover a wide range of applications and meet the demands of production plants for speed, accuracy, detection and the characterization of fine defects, as well as provide for records, display, analysis, etc.

Our in-line instruments allow you to monitor the fluctuation in the diameter of a wire or cable (drawing, extrusion ) as well as defect detection (flaw, lump and neck) especially for high speed lines.

Our wire measuring tools for your line of business

LDS was initiated in 1986  for in-line measurement of vibrationg fine wires. First, with one axis, then with two axes to obtain ovality values. Many drawing machine manufacturers and also drawing die manufacturers have integrated our LDS instrument in-line to measure fine wire products. On-board iffraction technology provides high-accuracy measurement (less than 1 µm) for each single value obtained, with no averaging required.

LPS was launched several years later to better meet extrusion concerns. With 3 measurement axes and shadow technology, it provides comprehensive data to monitor the dimensions of larger wires, tubes, pipes and cables. With its high-speed measurement capability, this measuring device characterizes defects and monitors fluctuations in diameter using only one gauge.

These easy-to-use, robust and high-performing gauges, will allow you to control and improve your manufacturing process.

Advantages of our instruments in measuring wire diameter

This optical measurement without contact is also wire vibration independent. The fact that there are no moving parts inside these gauges insures high reliability compared to mainstream, rotating-mirror technology widely used by the competition.

Our 30 years of experience guarantee you will benefit from the best measurement instruments on the market : accuracy, high-speed, repeatability, vibration independent gauges; these characteristics are the keys to our market leadersphip, and make CERSA-MCI stand out from the cometition.

    CIM PROD : PC software

    cim 1

    CIM PROD

    Our advanced CIM PROD PC software is a complete production quality management tool for technicians. It comes with our instruments to perform their parameter settings, to clearly display production measurements and the detected defects, and to generate real-time parameters and record all the measurements and events in a data base.
    The PROD version has been developed for IN-LINE wire & cable measurements. Adjustment of tolerances, and a triggering threshold are specific features for the production environment.

    Wire and Cable extrusion

    Extrusion is a process used to create objects with a fixed cross-sectional profile. A material is pushed through a die with the desired cross-section. The extrusion process can be done with the material hot or cold...
