Ultrasonic Film Thickness Meter

The ultrasonic thickness gauge emits high-frequency sound waves into the coating through a probe, receives the reflected echoes, calculates the round-trip time of the sound waves, and converts it into thickness based on the material's sound velocity. It is used to measure the thickness of paint and coatings on substrates such as metal and plastic, and to monitor coating quality in automotive and shipbuilding manufacturing.
Selection
When selecting, consider the substrate type and curvature: use high-frequency probes for metal substrates and low-frequency for plastics. The coating range determines the measurement range; for thin coatings, choose the 0-200μm model. For rough surfaces, use a delay block probe, and for high-temperature environments, use a specialized high-temperature probe. Verify the instrument's calibration certificate and measurement error values.

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.
