Inductive Digital Profile Measurement System for Contour and Surface Analysis

All surfaces contain measurable elements including size, shape, roughness, and waviness. High-precision components require comprehensive analysis of all these elements:

• Dimensions: Surface functional shapes defined by linear relationships between radius, angle, distance, and features
• Shape: Deviation from target surface shape (plane, sphere, cone, etc.), typically caused by machine error
• Roughness: Caused by factors such as cutting tools or machining processes
• Waviness: Non-ideal machine effects resulting from vibration, insufficient rigidity, or other process instability factors

Inductive profile sensor for small-range, high-precision contour measurement. The absolute linear accuracy of inductive sensors is range-dependent, with larger ranges resulting in lower accuracy. The measurement principle enables maximum resolution with infinite linear subdivision, eliminating inherent accuracy limitations.

Industrial applications include small-scale contour surface measurement such as bearing industry roller and raceway measurements (typically 5-10μm), mobile phone screen thickness measurement, backlight screen coating, and printed circuit coating thickness measurement in the mobile phone industry.
