Laser-based Thickness Measurement for Process and Finishing lines
The alpha.ti 5.0 is a high-precision laser thickness measurement system designed for continuous inline monitoring of metal strips up to 2 meters wide. Engineered for high-speed production environments, this system ensures exceptional accuracy and repeatability, independent of material type or surface characteristics.
Key Features of alpha.ti 5.0:
- High-Precision Laser Measurement: Achieves measurement accuracy starting from ±1.5 μm.
- Non-Contact Measurement: Uses laser triangulation for precise thickness detection without material contact.
- Adaptive Sensor Sensitivity: Automatically adjusts to various surface finishes.
- High-Speed Compatibility: Operates at strip speeds up to 2000 m/min.
- Dynamic Drift Compensation: Patented system compensates for any deformation in real time, ensuring long-term accuracy.
- Automatic Calibration: Continuous reference checks with integrated gauge blocks.
- Cross-Profile Analysis: C-frame design enables full transverse strip measurements.
- Minimal Safety Requirements: Uses Class 2 laser technology, eliminating the need for special safety precautions.
Flexible C-Frame Options for Optimal Coverage
The alpha.ti 5.0 system is available in multiple C-frame versions with measuring depths of 500 mm, 1000 mm, 1500 mm, and 2100 mm. These configurations support cross-profile thickness measurement while maintaining consistent precision across the entire width.
The patented drift compensation system ensures that measurement accuracy remains unaffected by mechanical deformations. A built-in deformation sensor monitors the frame's stability with 0.5 µm precision, automatically correcting for any structural shifts.
High-Resolution Data Acquisition & Real-Time Monitoring
- Ultra-Fast Sampling: Measuring frequency up to 67 kHz for real-time monitoring.
- Exceptional Repeatability: Factor of 10x better than accuracy rating.
- Multiple Measurement Ranges:
- 15 mm: Accuracy ±1.5 μm, Repeatability ±0.2 μm
- 25 mm: Accuracy ±2.5 μm, Repeatability ±0.4 μm
- 40 mm: Accuracy ±4.0 μm, Repeatability ±0.6 μm
Principle of Thickness and Cross-profile Measurement
With a measuring frequency of up to 67 kHz, strips over two meters wide can be measured along the strip direction, and in addition, in transverse strip direction for cross profile measurement.
