The new GreCon STENOGRAPH can reliably measure the raw density profile of MDF panels inline from a thickness of 6 mm up to a thickness of 42 mm. Thanks to an improved software and a construction that is even easier to maintain, the STENOGRAPH that is already established in numerous wood based panel plants is now even more efficient and robust.
The control unit can be installed at a distance from the production line. A user-friendly touch panel facilitates the operation of the system. The visualisation of measured data was adapted to the layout that is typical of GreCon systems which makes understanding and interpretation much easier.
The STENOGRAPH is working in a non-contact way and is usually installed at the press outlet where it measures the raw density profile in only a few seconds. A focused X-ray penetrates the moving endless panel at an angle of 45° and is measured in two positions: a stationary detector determines the transmitted radiation intensity, a moving detector measures the scattered radiation. The density-dependent values are combined in such a way that a density value can be allocated to each point of the panel cross section.
The raw density profile is one of the central material characteristics of wood based panels. The STENOGRAPH provides important information for the specific influence of the characteristics of wood based panels by reliably measuring the raw density profile.
