Measurement in the service of industry and heritage

METROLOGY & INSPECTION

Metrology is there to guarantee the precision, conformity and optimization of your industrial resources. It is also a way to preserve your assets.

A complete, end-to-end support service

First and foremost, it is essential for us to fully understand your objectives and requirements:


  • Why do you need these metrological readings? Is it for quality control, reverse engineering, deformation analysis, wear analysis, etc.?
  • Each part or piece of equipment to be measured may require a different approach depending on its size, geometry, materials, and tolerances.
  • What are the environmental constraints (light, space, temperature, humidity), means of access, regulatory requirements, or strict deadlines, co-activity, etc.?
  • Read more

    Based on all these parameters, we select the appropriate equipment and define a measurement protocol with an intervention procedure.


    Some interventions may require the design of specific tools, which we will then design and have manufactured in advance of the intervention.


    It is important to understand in detail what you expect from the deliverables because analyzing the results is essential to enabling you to make the right decisions:


    • Are the deliverables intended for remanufacturing a part? For internal quality control? For verifying specific dimensions?
    • Do you need raw data, or are you looking for interpreted reports with recommendations?
    • Are these one-off deliverables (e.g., at the end of an inspection) or recurring deliverables (periodic inspections with comparative analyses)?

    Our support goes beyond simply delivering results; it also includes a thorough analysis of the findings. Our goal is to help you interpret the results, identify anomalies or non-conformities, and propose corrective or preventative actions.


  • Tracker laser

    Combined with reflectors (±20 µm), a probe (±50 µm), and scanners (±60 µm to ±260 µm), within a 10 m radius, we can perform measurements on small parts or equipment of several cubic meters without contact or the use of adhesive strips or dye penetrant testing, regardless of their reflectivity. Possible applications include reverse engineering, quality control, equipment alignment and calibration, 3D printing, inspection, and analysis.

  • Handheld scanners

    (From 100 µm to 300 µm), portable, and wireless, these structured light scanners are highly maneuverable and capable of taking measurements in very difficult-to-access environments without contact or the use of stickers. With their integrated cameras, these scanners capture color and surface details to produce a realistic image. Possible applications include: reverse engineering, 3D printing, animation, museum design, inspection and analysis, virtual tours, and more.

  • Scanners laser 3D et drones

    These measurement methods are highly effective for inspecting large parts and structures. The drone, equipped with various sensors, can examine structures and equipment that are very difficult to access. Possible applications include inspection and analysis, leak detection, hot spot detection, etc.

Our metrological measurement methods

Non-contact measurement and inspection, non-destructive testing (NDT)

The combination of a laser tracker (for precision and spatial reference) and a scanner (to quickly capture 3D geometry) makes it possible to obtain a very efficient system for precise measurements and non-contact inspections.

  • Dimensional metrology

    Dimensional metrology allows objects to be measured with a very high level of precision:


    • High precision enabling the measurement of dimensions with deviations of up to 20µm, even on equipment several meters long and with a volume of several cubic meters.
    • Measurement of complex geometric shapes. Deviation analysis. Inspection of shapes and dimensions to verify the conformity of a part to a CAD model.
    • Verification of dimensional and geometric tolerances. Geometry control to verify alignment, parallelism, perpendicularity, coaxiality of surfaces, etc.
    • Deformation measurement: Comparison between the current part and its initial state to detect any deformations after machining, welding, or heat treatment.
    • Analysis of material wear by comparing measurements at different times.
      •

  • Reverse engineering

    Reverse engineering allows us to analyze an existing object in order to reproduce its design:


    • Capture the exact geometry of an existing part, even complex or worn, to produce a digital model usable in CAD software.
    • Reproduce old, broken, or unavailable parts. Quickly replicate them using 3D printing.
    • CAD/Reality Comparison: Superimpose the 3D scan with the digital model to identify discrepancies and update outdated or incomplete drawings.
    • Generate a deviation map to adjust manufacturing or validate a part.
    • Add tolerances, functional dimensions, and other data useful for manufacturing.
      •

  • Machine and tool alignment

    Aligning machines and tooling ensures production quality, extends equipment lifespan, reduces wear, and prevents production downtime.


    • Verify and correct linear and angular alignment between various machine components (shafts, rails, spindles, guides, etc.).
    • Machine tool installation: Verify the positioning and horizontality of machining centers, presses, etc.
    • Reduce positioning errors that can cause manufacturing defects or premature wear.
    • Assembly of large mechanical structures: Alignment of rails, linear guides, conveyors, etc.
    • Assembly and adjustment of industrial robots: Check the positioning accuracy of robotic arms.
      •

  • Technical drone inspection

    Inspection using drones equipped with sensors (cameras, LiDAR, thermal sensors, multispectral sensors, etc.) makes it possible to carry out surveys in areas that are difficult to access or extensive:


    • Monitoring of cracks, corrosion, and deformation (bridges, pylons, tanks, pipelines, etc.). Monitoring of the state of preservation of heritage sites. Inspection of buildings and civil engineering structures to detect cracks or subsidence.
    • Detection of gas leaks and thermal defects

Heritage conservation

Our solutions enable the preservation, analysis, and restoration of works of art and monuments with great precision:


  • Creation of ultra-precise 3D models to preserve a digital copy, share it or help with its restoration.


  • Preservation of fragile objects without contact, preventing any deterioration.


  • Time comparison to track the evolution of erosion or degradation.


  • Creation of virtual tours for museums or online platforms.


  • Create replicas for exhibition, without altering the original object.

Our metrological measurement equipment is portable and can be set up on-site using various tools that we design ourselves according to specific needs. This offers numerous advantages:


  • There is no need to dismantle or move a part. It can be measured directly in its actual environment, which is particularly useful for large parts or complex installations.
  • Reduced production downtime
  • Anomalies can be detected immediately on site, which avoids sending parts back to the workshop for inspection.
  • Possibility of evaluating the effects of temperature, mechanical stress or other environmental factors on the part or structure.


We operate in highly constrained environments such as nuclear, pharmaceutical, petrochemical, defense, etc.
