Ultra-thick coating thickness Gauge

The ultra-thick coating thickness gauge calculates thickness by measuring changes in magnetic flux or eddy currents between the substrate and the coating, based on the principles of magnetic induction or eddy current. It is used to inspect ultra-thick anti-corrosion coatings on ships, pipelines, and other structures, ensuring that construction meets thickness standards.
Selection
When selecting, consider the compatibility of the coating material with the substrate type and the probe principle. Magnetic induction is suitable for steel substrates, while eddy current is appropriate for non-ferrous metals. Choose the measurement range based on the coating thickness. The on-site environment determines whether a portable or fixed design is needed. Verify the instrument's calibration certificate and measurement accuracy.

Selection of Coating Thickness Gauges Using Magnetic and Eddy Current Methods on Different Substrates
This article introduces two main methods for coating thickness gauges: the magnetic method and the eddy current method. When choosing a method, the key is to determine it based on the electromagnetic properties of the substrate.
Application of Coating Thickness Gauges in Electroplating Thickness Detection
Coating thickness gauges are used to measure the thickness of electroplated layers, primarily employing the electromagnetic induction method for measuring non-magnetic coatings on magnetic substrates, or the eddy current method for measuring insulating coatings on non-magnetic metal substrates.
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.

The wire-wound drawdown bar directly quantifies the coating through the gap between wires, making it suitable for thin coating preparation with high precision, particularly for low-viscosity fluids. In contrast, the gap-type wet film applicator indirectly controls film thickness through the groove depth, with the actual coating thickness significantly influenced by material properties, making it more suitable for high-viscosity coatings and thick film preparation.
