Ultrasonic Film Thickness Gauge

The ultrasonic thickness gauge emits high-frequency sound waves into the coating through a probe, receives the reflected echoes, and calculates the propagation time of the sound waves in the material. By combining this with the known speed of sound, it converts the data into the thickness of the coating layer. It is used to measure the thickness of paint and coatings on substrates such as metals and plastics, and is employed in the automotive and shipbuilding industries to monitor coating quality.
Selection
When selecting, consider the substrate type and curvature: high-frequency probes are often used for metal substrates, while low-frequency probes are suitable for plastics. The measurement range must cover the thickness of the coating to be measured, and the accuracy should be selected according to process requirements, typically within ±1–3 μm. For environments containing dust or corrosive gases, choose models with a protection rating of IP65 or higher. Select standard or miniature probe sizes based on the measurement location.
