Thickness Gauges
The importance of thickness measurement in the flat rolled industry is fundamental to guarantee the quality and conformity of the finished products. During the production process of flat laminates, accurate thickness measurement allows the consistency and uniformity of the material to be assessed, ensuring compliance with the required specifications.

Control position
Static Single Point
Suitable solution for discontinous lines in which there is a time gap between two work session. The absence of piece to be measured is cerrtain moments does not require a moving frame. Usually the RUN position is the centerline of the strip.
Centerline Single Point
A standard solution for a wide range of application. A maintenance position is warranted any time required is required by moving to home position. Usually the RUN position is the centerline of the strip.
Centerline plus on demand profile scanning
A standard solution for a "slow" on demand cross profile scanning application where there is the possibility to stop the piece under the gauge A maintenance position is warranted any time required is required by moving to home position. Usually the RUN position is the centerline, and requesting the on demand scanning the frame will move to an edge to another automatically recognizing the borders and providing the cross section profile as well as the centeline, but alternatively.
3 points static
Ideal solution for a border plus centerline AGC contol with not moving parts.
3 kits continuous scanning
Ideal solution for a reliable profile and centerline solution, with 2 moving kits (borders) and a fixed kit (centerline).
Double technology
Automatic shift among different technologies without any noticeable difference on the operational side.
Open platforms
PC, PAC based architecture
From the first installation the PAC based design has exceeded Customer's expectation. The system maximize the use of top quality and highly available components including flexible modular IO management system and a robust all in one computer (Real Time Unix based kernel) and IO rack. The web based software was specifically designed by LGE engineers to take advantage of high speed processor available in today's industry. The resultant is a modern and reliable modular system, extremely fast, well beyond the requirements of the most closed-loop mill control systems.
PLC based architecture
An high performance thickness gauge that features the industry’s first open architecture. Designed on a PLC platform, its combination of advanced technologies make it accurate, versatile and robust; consistently outperform most other gauges on the market. It has been built with broadly available hardware and software components, including off-the-shelf PLC, PC, networking protocols and software. This reduces both initial costs as well as drastically cutting maintenance costs.
Automatic Gauge control
Our solutions find their natural application as ideal input for automatic gauge control systems. With our solutions we contributed to produce better, faster and safer for over 30 years.
While remaining specialists in the field of systems for harsh environments and critical applications such as hot and cold rolling processes (Hot Strip Mill, Tandem and Temper) in which our systems control the process online to guarantee the output thickness, in parallel we deal with systems that measure the thickness on finishing lines such as annealing, electrolytic, skin pass, recoiler. At the same time we have solutions for cutting and slitting lines in which in some case we use different and less demanding technologies to provide the suitable thickness output.
Our solutions cover thickness ranges ranging from aluminium foil with 7 microns target up to over 150 mm of hot steel, combining multiple technologies where necessary and guaranteeing accuracy, precision, robustness, reduced maintenance and ease of intervention. We offer a complete range of solutions for a 360° control for any gauging need.
