Smart Inspection Sensors
We seamlessly integrate customised sensor systems for precise dimensional accuracy, surface inspections, form and position tolerances and thread evaluation. These systems are designed for seamless integration into production and assembly lines. Our sensors with camera and lighting enable immediate implementation via standard interfaces. Our customised inspection programmes ensure efficient use.

Dimensional and surface inspection methods
Dimensional inspection
Inspection of all visible geometrical characteristics such as, for example, inner and outer diameter.
Height measurement
Measurement on up to 4 projection points to guarantee highly precise measurement results with tight tolerances. For instance, inclined upper edges can be detected with this method.
Surface inspection
Inspection of all surfaces on top and bottom side as well as all lateral surfaces of the parts to detect previously defined defects (defect catalogue). Different sensors with appropriate optical and illuminative components will be used to achieve the best possible contrast.
Example: Defect evaluation TOPside sensor with reflected light
Illumination
Various illumination types can be applied to enhance visibility of certain surface defects.
Example: Darkfield illumination for detection of damaged edge
Shape from shading
Shape from shading is a drift and curvature measuring 3D-method which can be used for shiny or inhomogeneous surfaces. In the example below, chatter marks are made visible with shape from shading technology.
Eddy current inspection
To detect defects in material or microstructure of conductive parts it makes perfect sense to use an eddy current inspection device. Eddy current will recognize a multitude of unwanted surface conditions and defects, such as fissures, dents, nitrided case thickness, or foreign material inclusions. It is further employed to identify hardened or tempered parts and sort out parts that are not hardened or insufficiently tempered. By inspecting the part’s microstructure one can also identify different alloys and distinguish between half-finished and finished products.
The eddy current inspection can be integrated fully into any NELA inspection system, without compromising productivity. The results of the eddy current inspection are transferred automatically to our VisionCheck image processing software and are also included into the statistical analysis of the inspection.
Renowned manufacturers of eddy current systems, such as Rohmann GmbH, are our partners.
