Ultrasonic Metal Thickness Gauge

The metal ultrasonic thickness gauge emits ultrasonic waves into the metal through a probe, receives the reflected echoes, calculates the propagation time, and converts it into thickness based on the speed of sound. It is used to measure the thickness of metal plates, pipes, and other materials from one side, and is commonly applied in corrosion monitoring and mechanical processing.
Selection
When selecting, consider that the measurement range should cover the sample thickness, and the adjustable sound velocity should accommodate different metal materials. The probe frequency should match the measurement accuracy requirements, and a high-temperature-specific probe is needed for high-temperature environments. Check the calibration certificate and the durability of the probe cables.

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.
Ultrasonic thickness gauge for detecting thick coatings and composite coatings.
Ultrasonic thickness gauges measure coating thickness using the principle of ultrasonic pulse reflection, calculating the result based on the propagation time of sound waves in the material and the speed of sound. When detecting thick coatings and composite coatings, challenges such as acoustic attenuation of the material, unknown sound speed, and signal recognition at multi-layer interfaces must be addressed.
