Real-Time Rolling Thickness Control with Tronsight Sensors

What is Rolling Thickness Measurement and Why is it Important?

Rolling is a metalworking process used to reduce the thickness and achieve a uniform cross-section of materials like steel, aluminum, and plastics. Rolling thickness measurement is the critical process of continuously monitoring and controlling the thickness of the material as it passes through the rollers. This is vital for maintaining product quality, ensuring material consistency, and meeting stringent industry standards. Inaccurate measurements can lead to wasted materials, product defects, and costly production downtime.

Comparison of Common Measurement Methods

While various methods exist for rolling thickness measurement, they each have their own limitations. Here's a comparison of common methods and their trade-offs:

The Principle and Process of Laser Triangulation Measurement

Tronsight’s TS-P series laser triangulation displacement sensor offers a superior solution. The principle of laser triangulation is based on geometric optics. A laser beam is projected onto the target surface at a specific angle. The light reflected from the surface is then collected by a receiving lens and focused onto a position-sensitive detector (PSD) or a CMOS/CCD array. As the target's distance changes, the spot of reflected light shifts on the detector.

The process is fast and precise:

1. Laser Projection: A focused laser beam is projected onto the surface of the rolling material.

2. Light Reflection: The laser spot reflects off the material's surface.

3. Sensor Detection: The reflected light is captured by the sensor's receiving lens and focused onto the detector.

4. Position Calculation: The detector calculates the exact position of the reflected light spot.

5. Distance Measurement: Based on the known triangulation geometry, the sensor's internal processor calculates the precise distance to the material surface. By using two sensors—one on the top and one on the bottom of the material—the exact thickness is determined.
