Optical fibers
SQM-Fine : Surface Quality Measurement
Contrôle
l’état de surface des fils, fibres optiques et câbles.
Made to answer an increasing demand for in line performing defect detection of wires, optical fibres and cables, the SQM reaches performances never got before. That has been possible due the very last optic and electronic technologies now available.
Rejections, production lost due to defects are a financial weight and a bad quality image for producers. The SQM can be paid back shortly, improving production efficiency and quality images of the producers.
Ξ Principle (International patent)
It works like a ring camera, with a constant number of dots on the circumference of the wire, independent of the position and vibration of the wire. The dot size is directly proportional to the wire diameter on the surface.
The instrument check each point individually and sequentially at very high speed and run 313 000 circumferences per second with 64 dots per circumference.
In the table here at right, is shown the characteristics of the detection
according to the wire diameter, line speed and number of dots.
Ξ Characteristics
Wire diameter range : 20µm to 2mm.

Ξ General functions
- Adjustable defect detection thresholds: shape, surface, frequency.
- Temperature compensated from 10 et 45°C.
- Serial link RS 232C/RS485
- Network connections.
- Wire length pulse count and speed computing.
- Statistical functions: defect size, frequency and density.
- Static relay outputs for alarm.
Ξ PC software for Windows
- Parameter setting, display and event journal recording with length.
- Production quality management for network connection.
One PC software for single sensor comes with the instrument. It can be used for detection parameter setting, maintenance, recording of event journals per spool.
