Magnetic Layer Thickness Gauge

Magnetic coating thickness gauges operate on the principle of magnetic induction, where a probe generates a magnetic field, and the thickness is calculated by measuring the influence of non-magnetic coatings on magnetic flux. They are used to detect the thickness of non-magnetic coatings such as paint and plastic on steel substrates, commonly applied in quality control for automotive and shipbuilding manufacturing.
Selection
When selecting, consider the substrate shape: use a standard probe for flat surfaces and a specialized probe for curved surfaces. Ensure the coating thickness range matches the instrument's measurement range. For humid environments, choose a waterproof model. Determine accuracy based on process requirements, with ±3% typically sufficient. Handheld models are convenient for on-site operations, while fixed models are suitable for assembly lines.
