nGauge X‑ray technology delivers accurate, real‑time thickness data during high‑speed rolling — helping you meet tight tolerances, reduce waste, and maximise yield.
In the demanding world of steel strip and plate production, thickness tolerances are tight and margins are tighter. LGE Engineering's nGauge is an X‑ray thickness gauge engineered to provide accurate, real‑time measurements during high‑speed processing — from hot strip mills to cold rolling tandems and finishing lines.
Based on the principle of mass absorption, the nGauge measures the amount of X‑ray radiation absorbed by the strip or plate. This non‑contact method is unaffected by surface condition, oil, or scale, making it ideal for harsh steel environments. The result: ±0.1% accuracy and a 10 ms response time — fast enough to feed automatic gauge control (AGC) and keep thickness within the tightest tolerances, even at maximum line speed.
What sets the nGauge apart is its role as the ultimate input for AGC systems. In a rolling mill, the AGC uses thickness deviation signals to adjust roll gap in real time. The nGauge's millisecond‑level response (calculation period as fast as 10 ms) enables closed‑loop control that reduces thickness variation, minimises scrap, and ensures consistent product quality from head to tail.
The nGauge is engineered for 24/7 continuous operation in the most demanding environments. Its rugged industrial design withstands heat, vibration, and contamination, while digital calibration standards allow fast, automated setup and standardisation — reducing downtime and operator error.
With the nGauge, LGE Engineering has standardised and unified decades of experience in X‑ray gauging for steel strip and plates. The system delivers the modern, reliable, and precise data needed to "produce better, faster, and cheaper" — meeting tight tolerances in high‑speed production.
