Ultrasonic Thickness Gauge Selection: Technical Considerations for Probe Configuration and Measurement Modes
This article primarily introduces the technical factors to consider when selecting an ultrasonic thickness gauge. In terms of probe configuration, the frequency affects both resolution and penetration depth, while crystal size determines adaptability to curvature and surface conditions.
