GMS1100
GMS1100 - Gypsum board dimensional measurement
Overview
The GMS1100 is a non-contact gypsum board measuring system using laser-based technology for measuring the full dimensional shape of gypsum board in-line during manufacture. The system measures and displays the thickness profile, taper profile, width and edge profile, wet and dry board lengths. Key values control values such as edge angle, taper width & height are all displayed and compared with tolerance limits. Trend graphs of key values including width, thickness and edge angles are plotted. All measured data is archived for quality assurance purposes.
The thickness is measured by a pair of PreciCura sensors which use the principle of optical laser triangulation, the width and edge profile is measured with a pair of ProfiCura-2D that use the principle of 2D laser optical triangulation. The length is measured using laser Doppler technology. The GMS1100 uses LIMAB’s standard PreciCura and ProfiCura-2D laser triangulation sensors which are a product of over 25 years experience of producing precision laser sensors. The unique laser sensors are robust, rugged yet very accurate and stable and are at the heart of the GMS1100. The laser measuring principle means that the product is measured without contact. There is no product compression when measuring the wet board and no wear. To ensure stable and accurate measurement in a factory environment that can vary in temperature LIMAB have developed a unique temperature stable mounting frame. This ensures long-term stability and eliminates the need for frequent calibration. To enable reliable measurement in the dusty gypsum environment the GMS11000 is equipped with an integrated forced air protection system. High volume air is provided by a fan/filter unit supplied with the system and means that maintenance is not required frequently. Continuous in-line monitoring of the product thickness, width and edge profile provides total process control allowing the boards to be produced on size reducing scrap and improving plant efficiency. The software provides a simple numeric and graphical interface so that operators can instantly see where problems are developing. Real-time thickness and edge profile graphs are provided, in addition, trend information can also be viewed. LIMAB provide a complete turn-key solution, one contractor takes full responsibility. The GMS1100 includes all the hardware and software needed for any factory installation. LIMAB provide commissioning, training and on-going product support and service.
