GMS1200 – Gypsum board dimensional measurement

The GMS1200 is a non-contact gypsum board measuring system that uses laser-based technology for measuring the full dimensional shape of drywall/ gypsum board in-line during manufacture.The system measures key board dimensions in real time. This includes thickness profile, taper profile and depth, width and edge profile, as well as wet and dry board lengths.GMS1200 operates with LIMAB’s PreciCura and ProfiCura lasers.

A fully web-based platform

The GMS1200 is built entirely on web technology, eliminating the need for dedicated client software and enabling access from any device with a browser — including smartphones and tablets.

Key benefits include:
• Access from any device and screen size, with automatic UI adaptation
• No client-side installation required
• Accessible across local networks, VPN, or the internet
• Headless server operation — no dedicated display needed
• Simplified updates — only the server needs to be updated
• Built to last — LIMAB’s GMS1200 is a future-proof platform with continuously expanding functionality.

Displayed drywall or gypsum board dimensions

Key control parameters are continuously monitored and compared against tolerance limits, including:
• Edge angle
• Taper width
• Taper height
Real-time trend graphs of key parameters, such as width, thickness, and edge angle, are displayed for process monitoring. All measurement data is archived for quality assurance and post-production analysis.

The easy way to see gypsum board size

Our modular non-contact measuring system provides accurate measurement of drywall and gypsum board dimensions throughout production. PreciCura optical laser sensors measure board thickness, width, and edge profile in real time, giving operators instant feedback, warnings, and process insights.

An optional width measurement after the mixer provides early verification of board dimensions, while the integrated GMS1200 length/shrinkage system measures wet and dry board length to optimize cutting accuracy and reduce scrap.

We also have a surface defect detection system, FalconEye II
