Surface quality analysis

U ntil now, the devices available on the market have been able to measure the diameter and detect geometrical defects of wires and cables, in the drawing, or extrusion processes. However, there was a lack of a device capable of measuring defects that can appear on the surface of a wire/cable during the manufacturing process, such as a lack of plating, scratches, or defects like impurities, bubbles or particles on the insulation.

High resolution cameras are limited to large diameters and low speeds. Until now, to analyze surface defects during production, one had to take a sample off the line and examinate it under a microscope. Our SQM allows "live" action, and therefore a faster correction of defects !

The SQM : our laser surface measurement

The SQM is a truly innovative, patented instrument, developped following insitent customer demand, to continuously check  the surface quality of fine wires in-line.

It works like a ring camera, all around the circumference of the wire. The image is analyzed in real-time by powerful algorithms in order to provide all necessary information about defects, such as their length, width, surface and localisation. Alarms can be generated according to the customer's requirements.

Our surface inspection system : a success with our customers

Numerous tests carried out on customers' applications have proven the SQM's capability and performance on fine wires. Used in combination with our LPS gauge for geometry defects like lump and neckdonw, the SQM will generate a complet image of the wire surface in order to detect any defect, shape disturbances, scratches, or platting missing. A real step forward in your quality process!

Like all other CERSA instruments, the SQM is a non-contact measurement system. It completes our line of dimensional measurement sensors on production lines.

Range Ø from 20 to 2000 µm (0,8 to 80 mils)



The SQM-F offers high-resolution and real-time surface defect detection on fine wires, cables and tubes with 128 pixels per circumference and 200,000 images per second. The defect image is displayed on CIM for customer analysis and characterization.
* Minimum linear resolution: 18μm
* 100% of the surface covered
* Real-time defect characterization

CIM PROD : PC software

cim 1


Our advanced CIM PROD PC software is a complete, production quality management tool for the operators. It comes with our instruments for their parameter settings, to clearly display the production measurements as well as the detected defects and generate real time parameters and records all the measurements and events in a data base.
Connected to the SQM-F, our software displays image and details of the defects, depending on adjusting tolerances and threshold.

How to detect surface defects on fine wires ?

When we think of measuring a wire or cable, we most often think of measuring its geometry, its electrical performance or its electrical insulutation. However, its external appearance is also of great importance for...
