CERSA MCI : a story of passionate engineers !


I nitially created to meet the automation and metrological needs of advanced industries (aeronautics, military,...), CERSA quickly extended its activities to continuous production industries (steel, plastic, wire, cable,...) with high-performance non-contact optical techniques.

The requirement for faster production and smaller dimensions, zero defects and material savings, have led us to develop high-performance metrology techniques at very high rate to insure the full in-line quality certification.

Fine wire specialist

As earlys as 1986, we developped the first Laser Diffraction Sensor (LDS) equipment for the online measurement of fine wire diameters. These instruments, appreciated worldwide both in production and in laboratory, are still an international reference and one of CERSA's flagship device.

In-line measuring instruments to fully certify the optical fiber

Early 90's, in close cooperation with optical fiber producers, CERSA developped the first Laser Interferometric Sensor for glass fiber (LISG-Glass). The great success of this instrument pushed us to develop other complementary devices : the Non Contact Tension Measurement (NCTM) and then the 5-axis Coating Monitor (CM5).

This line of instruments, associated with the CIM software (CERSA Instrument Manager) for acquisition, vizualization and data logging, is today used worldwide by the most important producers of optical telecommunication fibers, which places CERSA as world leader in this field. Always imitated, never matched !

What's next ?

The extrusion and wire drawing industries have been asking us for a long time for instruments that better meet their quality requirements. Extruded tubes, even multilayer tubes, which must be measured with precision (material cost) and speed (zero defects) require high-performance instruments.

The new range of LPS-H measuring instruments for larger diameter wires and cables, as well as the SQM instrument for the detection of surface defects on fine wires, plating defects (gold, silver, nickel,...) open up new perspectives and new markets for CERSA in the coming years.

In 2011, CERSA became part of the holding “Bellepeire Invest” BI group. Historical shareholders have decided to group key activities of three companies: ReneR (Renewable Energy Ressources), Pont du Pâtre (organic agriculture) and CERSA-MCI (automation and measurement engineering).

In May 2016, to support our significant growth, BI group moved to a brand new facility specially designed for us.

CERSA guide lines

For more than 30 years, CERSA-MCI is involved in training and technology research but is also  concerned by preserving the living environment.

Today, all BI team is aware and committed to this key matter. Our environemental code of ethics is as follow :

Spirit act :

  • The Earth is our unique living place, respect living conditions, we all depend on each other’s over the world.
  • Intelligence is shared over all humans, respect each other’s.
  • Difference is an enrichment.
  • We are in a chain and need to be a reliable link.
  • See, listen and learn on every things.
  • Invest in knowledge and technology mastering.
  • The right way might not be the usual way, innovate.
