Automatic Thickness Measurement System

The automatic thickness measurement system scans the surface of materials via sensor contact or non-contact methods, recording the distance difference from a reference plane to calculate thickness. It is used in production lines or laboratories to monitor the thickness uniformity of coatings, films, paper, and other materials, ensuring compliance with specification requirements.
Selection
When selecting, consider the material characteristics to match the measurement principle: contact methods are suitable for hard materials, while non-contact methods are ideal for easily deformable materials. Choose sensor resolution based on accuracy requirements, and determine the scanning frequency in combination with production line speed. Environmental adaptability must meet on-site temperature, humidity, and vibration conditions. The system should support data export formats that integrate with existing control processes.

Selection of Coating Thickness Measurement Methods: Coulometry vs. Dissolution in Electrolytic Thickness Gauges.
This article compares two techniques in electrolytic thickness gauges: the coulometric method and the dissolution method. The coulometric method measures coating thickness through electrochemical dissolution, making it suitable for single-layer metal coatings with simple operation and high accuracy. The dissolution method, on the other hand, measures thickness via chemical dissolution, making it more appropriate for multilayer or complex coatings.
