Thickness gauges for steel and aluminium mills

Non-contact measurement systems with micron accuracy for metals, plastics, rubber and composites. Real-time thickness monitoring and AGC integration.

Resources

Thickness gauges — key information

Wide applications

Proven in steel, aluminium, plastics, rubber and composites — hot & cold rolling, extrusion.

Field-proven reliability

Over 100 installations worldwide, with systems running continuously in the harshest mill environments.

30+ years field experience · 100+ customers

Micron precision

Repeatability up to ±0.5 microns, resolution 0.1 microns — ideal for tight-tolerance rolling.

Real-time control

Sampling rates up to 2000 Hz (LGauge) or down to 0.5 ms (nGauge) for high-speed processes.

Dual technology

LGauge (laser/confocal) for versatile materials; nGauge (X-ray) for extreme durability and metals requiring high penetrating power.

Digital sensors

Modern digital signal processing delivers stable, drift-free measurements over extended production campaigns.

Smart connectivity

Ethernet/IP, PROFINET, Modbus TCP, 4–20 mA — direct feedback to mill control systems.

Technical documentation

We choose inherently safer technologies wherever a feasible safer alternative exists.

High-performance closed-loop control for critical rolling applications. Multiple technologies, complete control, assisted by AI. Accurate thickness measurement is fundamental to guaranteeing the quality and conformity of finished flat-rolled products.
