Measurement of thickness (contactless)
Measures the material thickness of the product using a light curtain.
Calipro DMS measures the material thickness of the product using a light curtain. It is insensitive to colour, transparency and opacity as well as largely independent of the material surface.
- High profile resolution
- Material-independent (colour, density, components, etc.)
- Contactless, wear-free measurement
- No calibration effort
- No radiometric measurements
- Quick process optimization
- Material savings
- Quality assurance
Some areas of application in thickness measurement are difficult to cover with classic laser measuring systems. These systems reach their limits if the material surface is structured, rough, very smooth or glossy. Laser triangulation is not suitable either with multi-colour, transparent or opaque materials.
This is where the Calipro DMS LED shading sensor comes into play. The combination of eddy current sensor and shading sensor makes the measurement insensitive against material surface, colour, transparency, opacity and temperature variations.

The light of a LED is directed as uniform, parallel light beam onto a measuring object. The transition between the bright and dark area at the receiver is detected as measuring value. Depending on the material thickness, a certain area is thus shaded at the detector. The eddy current sensor measures the current roller position.
The material thickness is calculated from the difference between eddy current sensor and shading sensor.
