GreCon DMR 6000

Tactile Thickness Gauge DMR 6000 with High-Precision Rollers

Measurement is conducted by contact which allows an absolute measurement of dimensionally stable materials, such as MDF, OSB, particleboard, leather, caoutchouc, acrylic glass, insulating paper.

Design of the system

Frame concept

An optimal distribution of horizontal forces by a concentric track arrangement was considered in the design and provides for highest precision. The closed frame protects all components, such as cable and air channels, measuring head electronics and compressed air supply, against influences from the surrounding industrial environment. When installing the frame, a modification of the roller conveyor is only necessary in individual cases. Easily accessible inspection flaps allow an optimal access to the measuring system at any time.

Set-Point Positioning

The measuring heads stay in their position after the last measurement. This reduces the mechanical strain of both the panel edges and the measuring heads increasing the life of the measuring elements. Furthermore, the consumption of compressed air is also reduced. Even in case of a compressed air failure, the heads stay in their last position. The measuring heads are selected according to the material to be measured.

Measuring method



The Thickness Gauge DMR measures the thickness of solid materials by tactile measurement. A difference is made in the measuring principle between unilateral measurement and difference measurement. With the unilateral measurement, the material is scanned from only one side and a stop or a transport conveyor corresponding to the zero line is provided on the opposite side. With the difference measurement, the material thickness is calculated by scanning both sides and offsetting both values so that also vibrations and deflections can be compensated. First, the system must be calibrated without samples, and then the measuring process can start. The thickness is measured by scanning the material surface with rollers. A change of position results. This change of position is evaluated by an optical sensor (glass scale) with digital reading. Depending on the scope of change, electrical signals are transferred by optical scanning of the scale to an evaluation unit where they are counted. The measuring results determine the thickness of the measured material. Every measuring track is shown in a graphic on a screen including the measured value.

Thereby, it is possible to adapt the production to a sanding allowance.



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.
