Ultrasonic Thickness Measurement

Ultrasonic thickness measurement method allows you to measure the thickness of a piece by simply placing a probe on its surface—there is no need to access the opposite side.

Ultrasonic thickness gauges calculate material thickness by measuring the time it takes for an ultrasonic pulse to travel through the sample, reflect off the opposite side, and return to the probe. This method ensures accurate and reliable results.

These gauges are used to measure thickness, detect corrosion, and identify material delamination in homogeneous materials. They are compatible with sheet metals, coated materials, and other surfaces, provided there are no cracks, air bubbles, or defects that could disrupt the ultrasound signal. Depending on the model, they offer precision levels up to 0.1 mm, 0.01 mm, or even 0.001 mm. They are non-destructive, meaning they do not damage the material being measured. Some models can measure through coatings without needing to remove them, while others are suitable for composite materials like fiberglass and carbon fiber.

Ultrasonic thickness gauges are widely used in production, quality control, incoming and outgoing inspections, PED compliance tests, and non-destructive testing situations where access to both sides of the piece is not possible. Typical applications include use in mechanical workshops, shipbuilding, tube manufacturing, plastic processing, tank construction, and more.
