CERSA MCI, a story of passionate engineers!

Initially created to meet the automation and metrology needs of high-tech industries (aeronautics, military, etc.), CERSA MCI quickly expanded its activities to continuous production industries (steel, plastic, wire, cable, etc.) with high-performance, contactless optical technology.The demand for faster production and smaller dimensions, zero defects and material savings, have led us to develop high-performance metrology techniques for very high frequency full in-line quality certification.

Timeline Cersa


Fine wire specialist

As early as 1986, we developed 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 major producers of optical telecommunication fibers, which makes CERSA a world leader in this field. Always imitated, never matched!


BI group holding company

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 Resources), Pont du Pâtre (organic agriculture) and CERSA-MCI (automation and measurement engineering).


Company moves to new premises

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


What's next ?

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

Our new SQM-F 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.
2024 will also see the release of an offline version called the WIRE360 for detecting defects in samples of medical wires and tubes...

Research & Development

Electronic design

R&D has been a core part of CERSA since 1981. We maintain a close working relationship with our customers to insure we're all on the same headings, and that our R&D team works continuously on evolutions that match their needs.

3D design

Our customers can depend on our multi-skilled engineering team to obtain the best available technologies. Our instruments have the most highly evolved features and superlative performances levels to meet your needs.

Optics design

Because our customers expect exceptional performance from their measuring equipment, CERSA's teams include optics specialists capable of designing and integrating the most advanced, high-performance measuring systems. It's this technical mastery that makes our devices so different from the competition.

Software development

To offer its customers a flexible and powerful solution, CERSA has developed in-house CIM software capable of connecting to all instruments. Depending on the purpose (in-line or off-line), CIM offers a wide range of functions adapted to the user's needs.

CERSA-MCI also offers to put its 40 years of experience to the service of customers interested in developing specific instruments or functions for their needs with shared costs.

Production activities

Instruments manufactured in France

In order to ensure a constant and high-quality level of its products, CERSA-MCI has chosen to have its instruments conceived, assembled, adjusted and tested by a highly skilled team in one location… at our French headquarters.

Long life and maximum reliability

We also provide maintenance and upgrades for our instruments to extend their service life far past normal use. CERSA instruments are designed to provide maximum reliability.

Measurement tools have regular and reliable delivery times.

Regular, reliable delivery times

The efficiency of our production team, as well as our advanced procurement and stock management, guarantee smooth reliable delivery times.
