GreCon DML 6000

Laser Thickness Gauge DML 6000 for a Contactless Measurement


The Thickness Gauge DML 6000 measures the material thickness of solid, soft and humid materials by contactless measuring using laser beams. The measured values can be taken to the very edge of the material. Depending on the requirements, measurements can be made at stationary points or traversing across the whole production width. Traverse measurement allows measurement of a maximum amount of material and clearly shows any linear deformation of the material.

Design of the system

Frame Concept for each installation Situation

Different frame concepts are available for the Laser Thickness Gauge DML 6000:

  • steel
  • carbon

Taking into consideration the situation of use, it is possible to provide the frame in the best appropriate design.


Compensation of Material Vibrations

Preferably one measuring head is used above the board and one measuring head below the board to measure the thickness. By this installation in pairs, vibrations and deflections of the material can be compensated and thus do not influence the measuring result. Foil-type materials can be measured on one side against a precision roller. Measurement is conducted in a contactless way by an optical laser.


Laser Technology Depending on the Material to Be Measured

The selection of the possible laser technology for measurement is specified according to the material to be measured.



The DML 6000 is equipped with a calibration test function. Calibration is done below the production level and ensures consistent measuring accuracy.


Measuring method

The Thickness Gauge DML measures the material thickness of solid, soft and humid materials by contactless measuring using laser beams.
In terms of the measuring principle, measurement against precision rollers is distinguished from difference measurement. When measuring against precision rollers, the material is scanned only from one side and a roller is on the opposite side corresponding to the zero line. The difference measurement determines the thickness of the material by scanning on both sides and calculating both values. The thickness is calculated by triangulation. A laser beam is sent to the material surface and observed by a camera provided beside it. If the distance to the board changes, the observation angle changes too and consequently also the position of the image in the sensor is different. The distance to the measured value can be calculated based on the position of the image. Individual measured values determine the material thickness by offsetting.
Afterwards, every measuring track is shown with the measured value in a graphic on a screen.
The production can be adapted to material saving.


The user-friendly software of GreCon measuring system is based on the operating system Windows. Database, recipe administration and customized report functions provide those information the user needs quickly and clearly either in numerical or in graphical representation.
