Redefining Shape Inspection Accuracy & Efficiency

SWOTY 3D profilometer is engineered for strip production lines. Using non‑contact laser scanning, it reconstructs cross‑sectional profiles with micron‑level precision and outputs shape parameters in real time.

The system integrates high‑resolution laser sensors and intelligent algorithms to simultaneously measure width, thickness, crown, wedge, and waviness at an 800–100000 Hz scan rate. It is suitable for roughing, finishing, and temper mill processes.

The robust C‑frame design effectively resists vibration and thermal radiation, maintaining 0.001 mm accuracy even in harsh industrial environments.

How the Measurement Works

1

Laser Projection

A high‑power, modulated line laser is projected onto the surface of the moving steel strip, creating a bright, highly contrasted laser line.

2

Image Capture

A high‑speed industrial camera captures the image of the laser line as it deforms according to the strip's surface topography.

3

Real‑time Processing

Advanced onboard software calculates the exact 3D coordinates of thousands of points along the laser line in milliseconds.

Why It Stands Out

High‑Speed Scanning

Operates at frequencies that keep pace with the fastest production lines, ensuring 100% full‑length coverage.

Industrial‑Grade Robustness

IP67‑rated enclosure with advanced cooling systems, designed to withstand harsh industrial environments.

Real‑time Data Processing

Delivers measurement results in milliseconds, enabling immediate feedback to the mill's control system.

Multi‑Parameter Measurement

Simultaneously measures profile, crown, wedge, edge drop, and flatness in a single integrated solution.
