Automotive Thickness Gauge

Automotive thickness gauges utilize ultrasonic or eddy current principles, where a probe emits signals into the coating and receives the echoes, calculating the time difference of signal propagation to determine thickness. They are used to measure the thickness of automotive coatings and electroplated layers, ensuring coating uniformity and corrosion resistance. These gauges are widely applied in automotive manufacturing, maintenance, and quality inspection.
Selection
When selecting, consider the type of substrate being measured: use the magnetic principle for iron-based materials and the eddy current principle for non-iron-based materials. Choose the measurement range based on the coating thickness, with 0-2000μm being common. Check the accuracy error, typically ±1-3%. Portable devices are suitable for on-site use, while fixed types are used for assembly lines. The probe size must match the shape of the workpiece.
