Inline Diameter Measurement in Wire Drawing Using Optical Micrometers White Paper

This white paper discusses the challenges and solutions for high-accuracy non-contact diameter measurement of wire during the drawing process, particularly in harsh environments with lubricants and high-speed vibrations. It compares traditional laser scan micrometers with modern camera-based optical micrometers, highlighting how high-sampling-rate CMOS sensors and green LED illumination enable stable measurement unaffected by vibration.
