CERSA MCI : a story of passionate engineers !
I
nitially created to meet the automation and metrology needs of high-tech industries (aeronautics, military, etc.), CERSA quickly expanded its activities to continuous production industries (steel, plastic, wire, cable, etc.) with high-performance, non-contact optical technology.
The demand for faster production and smaller dimensions, zero defects and material savings, have led us to develop high-performance metrology techniques at very high frequencies to insure full in-line quality certification.
Fine wire specialist
As earlys as 1986, we developped the first Laser Diffraction Sensor (LDS) for the in-line measurement of fine wire diameters. These instruments, appreciated worldwide both in production and in the laboratory, are still an international reference and one of CERSA's flagship products.
In-line measuring instruments to fully certify optical fiber
In the early 1990's, in close cooperation with optical fiber producers, CERSA developed the first Laser Interferometric Sensor for glass fiber (LIS-Glass). The great success of this instrument motivated us to develop other complementary devices : the Non Contact Tension Measurement (NCTM) and then the 5-axis Coating Measurement (CM5) instruments.
This line of instruments, associated with our CIM software (CERSA Instrument Manager) for the acquisition, display and recording of measurements, is now used worldwide by the most important producers of optical telecommunication fibers, which makes CERSA a 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.
Our new range of LPS-H measuring instruments for larger diameter wires and cables, as well as our SQM instrument for the detection of surface defects on fine wires, plating defects (gold, silver, nickel, etc.) are opening up new perspectives and new markets for CERSA in the coming years.

Production activities





Bellepeire Invest. Group

In 2011, CERSA became part of the “Bellepeire Invest” BI group holding company. The baseline shareholders decided to combine the 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 has been involved in training and technology research but is also concerned with preserving the natural environment.
Today, the entire BI team is aware of and committed to this essential focus. 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.
