CERSA-MCI, leader of measurement and control instruments

B ased in France, CERSA-MCI is a world-leading manufacturer of measuring devices for fine wire, cable and optical fiber industries. Since 1981, CERSA has provided solutions based on advanced technologies to help customers enhance their production quality. Our mastery of the physical phenomena, especially optical, and the use of the most innovative technologies, allows us to offer performance levels that suit present and future needs.

Our R&D engineers, experts in optics, electronics and signal processing, design all our devices. Our team of experienced technicians takes care of our production with final assembly and testing of these sensors. Everything is designed, assembled, adjusted and tested in France to insure total control of the processes. Particular attention paid to the details makes our devices reliable and robust for daily use in the harsh conditions of workshops and manufacturing plants.

In cooperation with fine wire specialized foreign national and university laboratories such as METAS and NIST, CERSA-MCI has developed a complete process for ultra-fine wire calibration. We also have developed a complete test and validation procedure to certify the performance levels of each instrument provided.

Our teams provide preventive maintenance, repairs, calibration or even hardware and software retrofits for your sensors. We can also assist you with the commissioning and training in the use of our devices.



Established in the South of France, CERSA-MCI is today a world leader in the design and production of advanced instruments and global measurement solutions. Our line of measurement instruments is derived from close cooperation with our customers, and a continuous, substantial investment in research and development to meet the requirements, both for production lines and for use in laboratories. Our long-standing, broad-based cooperation with external research laboratories, our internal mastery of design, production, assembly and final tests, enable us to guarantee high performance levels, quality and durability, as well as to provide efficient technical support.

CERSA-MCI has an office in Wuhan, China, for the technical support of our customers and for product maintenance throughout Asia, as well as a worldwide network of representatives able to assist our customers locally.

The largest companies in our fields have chosen CERSA-MCI for their most demanding

Our measurement solutions are customized to fit your needs

O ur product range covers in-line and off-line applications for non-contact measurement. High-frequency measurements and high accuracy measurement are the essence of our devices.

We offer a comprehensive range of devices specifically designed for optical fiber manufacturers. Solution to insure full quality certification of the fiber during the drawing process. Today, the major plants the world over are equipped with our products for the measurement of bare fiber, as well as coated fiber. Now available with multi industry standard communications (field buses).

Our well-known LDS range (Ø from 5 µm to 2000 µm), developped over more than 20 years for laboratory applications and continuously improved, is still the best solution on the market for tiny wires. When fitted with our WSR accessory (for 360° measurements) and combined with CIM Lab software, it becomes a complete solution to enhance wire quality. It is also available with 2 axes for in-line measurement of fine wires.

Focused on high speed line measurement, the new SQM-F (patented technology) catches surface defects and displays their shape on the screen. Now available for round products from 20 µm to 2000 µm. This is a complementary geometrical measurement gauge solution to improve quality inspection.

The LPS-3-H sensor was developed to monitor wire diameter and detect lumps & neckdonws in a single product for larger wire and cable diameters (Ø from 0.3 mm to 5 mm). With an acquisition speed of 20 kHz and 3 axes, it far exceeds the capabilities of other devices available on the market.

Our CIM PC software, available in PROD or LAB version, provides data display, data logging, allows you to obtain statistics, analyses and printouts of the measurements for any CERSA device. This complete solution is highly appreciated by technicians for its advanced functionalities.
