DML 5000
Inline Laser Thickness Measurement for Quality and Production Assurance
The inline laser thickness gauge DML 5000 measures the thickness of different materials in a non-contact way. It is used for production control and quality assurance.
The system is preferably used wherever surfaces do not allow contact with the system or soft and moist materials have to be measured. The non-contact scanning by the laser beam also makes measurement up to the material edges possible.
This measuring system helps you produce a consistent quality and thus brings you a considerable economic benefit.
Fluctuations in material thickness are undesired in a production line. By means of a continuous measuring system, deviations from nominal values can be reduced. In view of the required quality standards, this leads to an increase in quality and thus to an economic benefit while permanent over-tolerance in the production is reduced, which may lead to substantial material savings. The DML 5000 laser thickness gauge evaluates the measured material inline, i.e., during running production, and represents the measured data of the current production process.
An optimum use of raw material is attained by signalising any deviation from tolerance limits. Critical production trends are indicated at an early stage, effective counter-measures can be taken. A data feedback from the laser thickness gauge DML 5000 to a process control system makes the development of an optimum control process possible. Run-in times for product changes are minimised.

Design
Almost any kind of installation solution is possible through the modular design of the system components. Relocation or modifications are easily possible within short time periods. The measuring system is designed individually as per the requirements and the situation on site. It can be conceived as stationary (DML) or traversing version (DML-Q). Traverse measurement across the entire production width allows control of a maximum amount of material and shows any deformation of the material.
Measuring Principle
Generally, there are two measuring principles:
Triangulation measuring principle:
A laser diode directs a light spot onto the material to be measured. The light spot that is reflected by the material is focussed by a light collector and scanned by a photosensitive position receiver. A change in distance of the material causes a change in angle of the reflected light spot on the position receiver. The input signal at the receiver changes and so does the measured value.
Shadow laser technology:
A laser diode transmits a beam of rays to an opposite photodiode which converts the incoming light into an analogue video signal. The definitive thickness of the measured material is calculated from a change in material thickness and the resulting change of the electronic signal.
Construction of the System
Up to 11 measuring tracks can be installed next to each other on a frame that consists of patented aluminium profiles, which integrates the cable and air channels and thus protect the supply and measuring lines against negative surroundings. An air purge unit prevents dirt accumulation on the measuring sensor. The measuring system can be controlled via a touch panel.
Combination with Other Measuring Systems
Various GreCon measuring systems can be combined according to a modular principle to form a quality centre. A combination of a GreCon thickness gauge and a GreCon weight per unit area gauge provides important guideline values for production, such as average raw density. Data transfer to a process control system makes the development of an optimum control process possible. Run-in times for product changes can be considerably reduced.
