Continuous Thickness Gauge

Continuous thickness gauges measure material thickness non-contact via sensors, using radiation, ultrasound, or laser signals that penetrate or reflect to calculate thickness values. They are used for real-time monitoring of thickness uniformity in coatings, films, sheets, etc., on production lines, ensuring consistent product specifications in industries such as coatings, plastics, and papermaking.
Selection
When selecting, consider the compatibility between material properties and measurement principles. X-ray methods are suitable for metal coatings, while ultrasound is used for multilayer structures. Determine the response frequency based on production line speed, and incorporate heat-resistant designs for high-temperature environments. Evaluate the error range by combining precision requirements and budget constraints, and verify the ease of calibration and maintenance for the equipment.

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. Dual-element probes offer a smaller dead zone compared to single-element probes, and delay-line probes are suitable for thin-wall and high-temperature applications.
