Textile thickness gauge 312 XRT

filmplasticfor sheet materials

Overview
The Nordson 312 XRT X‑ray gauge provides precise thickness and basis weight (basis weight) measurements tailored to plastics extrusion, converting/coating, calendering and textile production. The sensor delivers high measurement stability, wide operating range and strong tolerance to product flutter. A low‑energy option is available for lightweight materials and typically reduces licensing requirements in many countries.

Features & Benefits

• Fast, repeatable and high‑precision thickness and basis weight measurements.
• Wider operating weight/thickness range compared with comparable isotopic gauges.
• Precisely regulated high‑voltage supply for stable, long‑term measurement performance.
• High scan speed — up to 500 mm / 20 in per second.
• Minimized regulatory burden — zero radiation hazard when powered down.
• High tolerance to product flutter and no source degradation over time.
• Low‑energy option for superior accuracy on lightweight products; generally reduces licensing needs in many regions.

Applications

• Plastics extrusion (extruded film and sheet) — inline thickness and basis weight control.
• Converting and coating processes — basis weight and coat weight monitoring.
• Calendered products — thickness control and process feedback.
• Textiles and nonwovens — basis weight and thickness inspection.

Technical specifications
